Opinion

This is a genuine aquaponic experiment, not a hydroponic-only study — a real common/grass/silver carp polyculture RAS feeds a floating-raft tomato system, run head-to-head against a synthetic-nutrient-solution hydroponic control. (The task brief flagged the possibility of a pure-hydroponic paper by analogy with pastorarbuluEnhancingGrowthYield2025; that turned out not to apply here — full fish/RAS Methods sections, water-quality tables and carp harvest data are all present.) The design is unusual for this vault: the primary treatment factor is not stocking density or system type but foliar micronutrient spray (K, Mg, Fe, Mn, B, Zn, Cu vs. untreated control), crossed factorially with growing system (aquaponic vs. hydroponic), 3 replicate growth-bed rows per cell. This makes the paper simultaneously an AP-vs-HYD comparison AND a foliar-fertilization trial, and I split it into 8 trials.csv rows (one per foliar-nutrient level) rather than pooling. The main weakness for data extraction is that the paper’s own headline result — fruit yield, fruit number, and cluster number, all clearly measured and analyzed (Duncan’s letters on every bar) — is reported only as bar charts (Figs. 2-4), with zero numbers anywhere in text or a table. Per this vault’s never-read-a-figure rule, AP/HYD are NR in all 8 rows despite yield being the paper’s central finding; only the vegetative-growth table (Table 3: fresh/dry biomass, node/leaf number, height) and the pigment/SPAD/fluorescence table (Table 4) have actual numbers, and even Table 3’s per-organ weights don’t sum to a single reportable “plant fresh weight” without derivation. One internally-resolvable numeric conflict on fish stocking density (Methods vs. Results) is flagged WARN-MATERIAL below; a likely EC unit-label typo is WARN-MINOR. Worth citing for its foliar-correction angle (an under-explored remediation for aquaponics’ well-known low-K/Fe/Mn/B water) and because it resolves a #todo citation already pending in pinedapinedaResponseTilapiaTomato2020.

Abstract

An aquaponic system was designed to investigate effects of foliar applications of some micro- and macronutrients on tomato growth and yield in comparison with a hydroponic system. Common carp, grass carp and silver carp were stocked in the rearing tanks at 15, 20 and 15 fish m−3, respectively. The fish were fed three times daily with a pellet diet containing 46% protein. Fourteen days old tomatoes seedlings were transplanted on to growth bed units of aquaponic and hydroponic systems after stocking of carp fish for 2.5 months in the rearing tanks. Foliar nutrients application began 30 days after transplantation. Eight treatments were used, untreated control, foliar application at the rate of 250 mL plant−1 with 0.5 g L−1 K2SO4, MgSO4·7H2O, Fe-EDDHA, MnSO4·H2O, H3BO3, ZnCl2, and CuSO4·5H2O. Plants were sprayed twice a month. The results showed that biomass gains of tomatoes were higher in hydroponics as compared to aquaponics. Foliar application of K, Mg, Fe, Mn, and B increased vegetative growth of plants in the aquaponics. In the hydroponics, only Fe and B had positive effects on plant growth. Cluster number per plant in aquaponics was lower than in hydroponics treatments, but it increased with foliar application of elements. There was no difference in fruit number and yield between aquaponics and hydroponics grown plants in the control treatments. Except Cu, foliar spray of all elements significantly increased plant fruit number and yield in the aquaponics in order of: K > Fe > Mn > Zn > Mg > B. In the hydroponics, foliar application of K, Mg and Zn increased fruit number and yield of plants compared to control. These results indicated that foliar application of some elements can effectively alleviate nutrient deficiencies in tomatoes grown on aquaponics.

Summary

The authors built a 3-replicate Rakocy/UVI-style aquaponic system (carp rearing tank → clarifier → filter tank → degassing tank → floating-raft growth bed) at Vali-e-Asr University, Rafsanjan, Iran, stocked with a common carp / grass carp / silver carp polyculture, and ran it alongside a 3-replicate hydroponic control fed a standard modified-Hoagland-type nutrient solution. After the carp had conditioned the system for 2.5 months, 14-day-old tomato seedlings were transplanted into both systems and, from 30 days post-transplant, sprayed twice monthly for the rest of the 108-day trial with one of seven foliar micronutrient treatments (K2SO4, MgSO4, Fe-EDDHA, MnSO4, H3BO3, ZnCl2, CuSO4, each 0.5 g/L, 250 mL/plant) or left as an untreated control — a full 2 (system) x 8 (foliar treatment) factorial, 3 replications. At harvest they measured vegetative biomass (fresh/dry mass of leaves, stems, roots), node number, leaf number, height, SPAD chlorophyll index, chlorophyll fluorescence (Fv/Fm), leaf pigments (chlorophyll a/b, carotenoids), and reproductive output (cluster number, fruit number, fruit yield, fruit fresh mass). Aquaponic plants had consistently lower vegetative biomass than hydroponic plants across every foliar treatment, attributed to the aquaponic system’s naturally low K, Fe, Mn and B (confirmed by the paper’s own water-chemistry table). Foliar K, Mg, Fe, Mn and B all significantly increased aquaponic vegetative growth relative to the aquaponic control, whereas only Fe and B did so in hydroponics — consistent with the aquaponic water being the more nutrient-limited environment. Reproductively, foliar spray of every element except Cu significantly increased aquaponic fruit number and yield (order K > Fe > Mn > Zn > Mg > B), while in hydroponics only K, Mg and Zn increased yield and B/Cu actually decreased it relative to control. Aquaponic leaves were paradoxically greener (higher chlorophyll a, higher young-leaf SPAD in the control treatment) than hydroponic leaves, which the authors attribute to more ammonium uptake in the fish-water system. The paper’s own water-quality table shows nitrite above the authors’ cited tolerance limit (1.57-1.69 vs. <0.2 mg/L) throughout, without any stated ill effect on carp survival (100%) or growth.


Experiment data

  • Location: Vali-e-Asr University of Rafsanjan, Rafsanjan, Iran; greenhouse, 13h light (26±3°C) / 11h dark (22±3°C) phases, RH 52.4-63.2%
  • Design: 2 (growing system: aquaponic/hydroponic) x 8 (foliar treatment: untreated control + K, Mg, Fe, Mn, B, Zn, Cu) factorial, completely randomized design, 3 replications (independent growth-bed rows/units per system — 3 aquaponic units, 3 hydroponic units, Fig. 1); 8 plants/growth-bed unit, one per foliar treatment
  • Replicates / n: 3 (growth systems/rows) per system x foliar-treatment cell
  • Duration: Carp stocked and system conditioned 2.5 months before transplant; tomato seedlings (14 d old) transplanted, foliar spray began 30 days post-transplant (twice/month thereafter), trial concluded at 108 days post-transplant (fruit harvested weekly, 84-106 days post-transplant); total carp culture time to harvest “6 months”
  • Organisms: Common carp (Cyprinus carpio) / Grass carp (Ctenopharyngodon idella) / Silver carp (Hypophthalmichthys molitrix) (polyculture) / Tomato (Solanum lycopersicum) (cultivar not stated)
  • Statistics: Two-factor factorial ANOVA (SAS program); Duncan’s multiple range test post-hoc when F-test p<0.05 (Methods 2.4)
  • Vegetative growth (Table 3): Hydroponic > aquaponic across every foliar treatment for leaf/stem/root fresh mass, leaf/stem dry mass, leaf number, node number and height (P<0.05 for the system main effect). Within aquaponics, foliar K produced the largest biomass gains; within hydroponics, foliar B and Mg produced the largest gains.
  • Reproductive growth (Figs. 2-4, chart-only, no numeric values in text): No AP-vs-HYD difference in fruit number/yield at the untreated-control level. Except Cu, every foliar element significantly increased aquaponic fruit number and yield, order K>Fe>Mn>Zn>Mg>B. In hydroponics, K/Mg/Zn increased yield; B/Cu decreased it.
  • Chlorophyll content / SPAD (Table 4): Aquaponic control had higher young-leaf SPAD and chlorophyll a than hydroponic control; no system difference in Fv/Fm.

Vegetative growth (biomass, height, node/leaf number)

This paper: Table 3 gives full leaf/stem/root fresh and dry mass, node number, leaf number and height for all 16 system x nutrient cells. Hydroponic plants exceeded aquaponic plants for every biomass/growth variable at essentially every foliar-nutrient level (Results 3.3, p.397: “There was a significant difference (P<0.05) between two systems in terms of biomass gain”). Within the aquaponic system, foliar K gave the single largest response across almost every variable (LFM 515±40 vs. control’s 273±18 g/plant; RDM 61.2±1.3 vs. 42.9±1.9 g/plant), followed by B, Mn, Fe and Mg; foliar Cu did not improve aquaponic growth over control on most variables. Within hydroponics, only Fe and B exceeded the hydroponic control on most variables (Results 3.3: “In the hydroponics, only Fe and B had positive effects on plant growth”). The authors attribute the aquaponic system’s overall growth deficit to its water chemistry (Table 2: no P/K/Fe/Mn/S fertilization beyond fish excretion and a Fe-EDDHA root-zone top-up), and the foliar-K effect specifically to potassium not being added to fish feed and therefore chronically low in aquaponic water — a mechanism corroborated by Graber and Junge (2009)‘s report that fish water K was 45x lower than hydroponic solution in their own system (secondary citation, not this paper’s own measurement).

Compared with:

  • todo Pereira 2002 — lettuce irrigated with fish effluent had increased shoot fresh matter vs. well water, but no difference when both were chemically fertilized; framed as consistent with this paper’s foliar-supplementation-corrects-the-gap finding (Results 3.3, p.397-398)
  • todo Kaya et al. 2001 — foliar K increased tomato dry matter under salinity stress; cited as corroborating this paper’s foliar-K vegetative growth response (Results 3.3, p.398)
  • todo Tisdale et al. 1985 — similar foliar-K growth response observed, cited alongside Kaya et al. (Results 3.3, p.398)
  • todo Graber and Junge 2009 — fish water K reported 45x lower than hydroponic solution K, resulting in poorer tomato fruit quality (aquaponic fruit 22.0 g K/kg DM vs. hydroponic 40.8 g K/kg DM, secondary figures from that paper’s own system, not measured here); cited as the mechanistic basis for this paper’s foliar-K result (Discussion, p.399-400)

Reproductive growth: cluster number, fruit number, yield

This paper: Reported entirely as bar charts (Figs. 2-4) with Duncan significance letters and no numeric values anywhere in text or a table, so AP/HYD and no dedicated fruit-count/cluster-count columns hold any number for this paper (see Extraction notes). Qualitatively: cluster number per plant was lower in aquaponics than hydroponics at the control level, but increased with foliar application, most in aquaponic K and Fe treatments (Fig. 2); Cu decreased cluster number in hydroponics but had no significant effect in aquaponics. There was no significant AP-vs-HYD difference in fruit number or yield in the untreated-control treatments (Figs. 3-4) — a result the authors note agrees with Graber and Junge (2009)‘s finding of no yield difference between hydroponic and aquaponic tomato. Except Cu, every foliar element significantly increased aquaponic fruit number and yield, in the stated order K>Fe>Mn>Zn>Mg>B (Results 3.4, p.398). In hydroponics, K, Mg and Zn increased fruit number/yield vs. control, while B and Cu decreased them (Results 3.4). Fruit fresh mass (Fig. 5, per-fruit weight) showed smaller, less consistent differences than fruit number/yield.

Compared with:

  • todo Graber and Junge 2009 — no difference in fruit yield between hydroponically and aquaponically grown tomatoes, corroborating this paper’s control-treatment finding (Results 3.4, p.398)
  • todo Castro et al. 2006 — fish-effluent irrigation increased cherry tomato fruit number and productivity across the first three harvests, though with lower mean fruit weight — a fruit-number/fruit-weight trade-off the authors liken to their own foliar-treated aquaponic results (Results 3.4, p.398-399)
  • todo Prinsloo and Schoonbee 1987 — fish-effluent irrigation raised tomato yield from 64.5 to 95.8 t/ha vs. well water, cited as further precedent for fish-water-driven yield gains (Results 3.4, p.399)
  • todo Davis et al. 2003 — field-grown tomato: foliar B increased shoot/root dry weight and improved fruit set and total yield, cited as corroborating this paper’s foliar-B reproductive response (Discussion, p.399)

Water quality and system chemistry

This paper: Table 2 gives full growth-bed influent/effluent water chemistry. All fish-production-relevant parameters (pH, EC, DO) were within the paper’s own cited tolerance limits except nitrite, which averaged 1.57-1.69 mg/L against a stated <0.2 mg/L limit throughout the trial (Results 3.1, p.397) — noted by the authors as the one out-of-range parameter, without any stated consequence for carp survival (100% in all three species) or growth. The authors argue the aquaponic system’s alkaline pH (7.7) further suppresses Fe/Mn/Zn/B availability and uptake on top of the raw concentration deficit, strengthening the case for foliar correction (Discussion, p.399-400, citing Bertoni et al. 1992 and their own Roosta 2011).

Compared with:

  • todo Boyd 1992; Boyd and Tucker 1998 — pond/aquaculture water-quality tolerance limits, source of Table 2’s reference column
  • todo Bertoni et al. 1992 — alkaline pH decreases Fe/Mn/Zn/B availability and uptake, cited as the mechanism compounding this paper’s aquaponic nutrient deficiency at pH 7.7 (Discussion, p.399)
  • todo Roosta 2011 — water alkalinity x nutrient solution pH interaction on lettuce Mg/Fe/Mn/Zn concentrations, this author’s own prior work, cited alongside Bertoni et al. for the same pH-availability mechanism

Chlorophyll, SPAD and fluorescence

This paper: In the untreated control, aquaponic plants had significantly higher young-leaf SPAD (40.08±0.65 vs. 34.47±2.51) and chlorophyll a (1502±37 vs. 1276±18 nmol/g FW) than hydroponic plants, despite lower vegetative biomass — the authors attribute this to greater (non-toxic) ammonium uptake by tomato roots in the fish-water system, citing their own prior cucumber work (Roosta and Schjoerring 2007; Roosta et al. 2009). Foliar Mg and Fe significantly increased chlorophyll b in both systems relative to control; foliar Mg also raised carotenoid content specifically in aquaponics. Maximal PSII quantum yield (Fv/Fm) did not differ significantly between systems or among foliar treatments for either young or old leaves (Table 4) — the one measured variable showing no system effect at all.

Compared with: (no external literature comparison given for the SPAD/pigment/Fv/Fm results specifically beyond the ammonium-uptake mechanism citations above)

Extraction notes

This paper IS a genuine aquaponic experiment, not a hydroponic-only study. The task brief for this extraction speculated, by analogy with pastorarbuluEnhancingGrowthYield2025, that a “foliar application” title might signal a pure-hydroponic paper with no fish/RAS component. That is not the case here: Methods 2.1 describes a full 3-unit Rakocy/UVI-model RAS (fish rearing tank, clarifier, filter tank, degassing tank, floating-raft growth bed per unit), stocked with a common/grass/silver carp polyculture, with its own water-quality table (Table 2) and carp harvest data (Results 3.2). The fish/aquaponic block is fully populated (not NA) across all 8 trials. The paper’s “hydroponic” arm is a genuine parallel control system (separate nutrient-solution troughs, Fig. 1b), not the paper’s only growing condition.

Trial structure (8 rows, not 2 or 16): The paper is a full 2 (growing system: AP/HYD) x 8 (foliar nutrient: control + K/Mg/Fe/Mn/B/Zn/Cu) factorial, 3 replications, arranged as a single completely randomized design (Methods 2.4). Per SCHEMA.md, one row was created per aquaponic treatment — here, “aquaponic treatment” is naturally read as one row per foliar-nutrient level (the paper’s crossed factor), with AP/HYD-labelled cells holding that foliar-nutrient level’s aquaponic and hydroponic values respectively (i.e., paired by nutrient, not by presence/absence of foliar spray). This differs from the more common vault pattern where one hydroponic control is shared unchanged across several aquaponic rows (e.g. pantanellaAquaponicsHydroponicsProduction2012): here, EVERY row’s HYD value is itself a distinct, independently-measured hydroponic-plus-foliar-treatment combination, because the paper’s own statistical design treats foliar nutrient as a factor applied identically to both growing systems. This is stated explicitly in each row’s TRIAL DEFINITION. An alternative design (2 rows: AP-vs-HYD pooled across nutrient, or 7 rows: only the treated nutrients, folding Control into both) was considered and rejected, because the paper reports and analyzes each system x nutrient cell as its own group (Table 3/4 give per-cell means with individual Duncan letters, not factor main effects only) — matching the interaction-preserving logic already used for pastorarbuluEnhancingGrowthYield2025’s 6-row 2x3 factorial.

⚠️WARN-MATERIAL — Initial Stock density, all three carp species (Methods 2.1, p.396 vs. Results 3.2, p.398). Methods: “Common carp…, grass carp…, and silver carp… were stocked in the rearing tanks (diameter 1.2 m, water depth 0.75 m, and water volume 848 L) at 15, 20 and 15 fish m−3, respectively.” Results: “Common carp, grass carp and silver carp were stocked at 17.69, 23.58 and 17.69 fish m−3, respectively.” Both sentences describe the same stocking event in the same units (fish m⁻³), but give different numbers for all three species. Checked: 15 ÷ 0.848 m³ (Methods’ own stated tank water volume) = 17.69; 20 ÷ 0.848 = 23.58; 15 ÷ 0.848 = 17.69 — an exact match (to 2 decimal places) for all three species. This strongly indicates Methods’ “15, 20, 15” are raw per-tank fish COUNTS mislabelled with a fish/m³ unit, and Results independently reports the correctly computed densities using the tank volume Methods itself states two paragraphs earlier. Recorded 17.69/23.58/17.69 fish m⁻³ (Results’ values) in the Initial Stock density cell for all 8 trials, as the more defensible reading; Methods’ “15, 20, 15” preserved in each row’s Experimental Remarks as the likely source of the mislabelling. Does not affect FCR (1.43, independently stated once), survival (100%, independently stated once), or harvest-mass cells (independently stated per species). Not added to REVIEW.md — this is MATERIAL (a defensible choice with a documented basis), not BLOCK/CHECK.

⚠️WARN-MINOR — EC unit label, Table 2 (p.398). Printed as “EC (Ms/cm)” — read literally (mega-Siemens/cm) this would be physically absurd for aquaculture water (many orders of magnitude too high; the paper’s own tolerance-limit column states EC should be <1.2). The measured values (0.51-0.54) are exactly the right order of magnitude for mS/cm (=dS/m), a standard water-EC unit, so this is treated as a capitalization typo (mS → Ms) rather than a value error. No cell affected — 0.51/0.54 recorded as printed, unit corrected to dS/m (equivalent unit, not a numeric conversion).

Judgment call — SPAD (aquaponics) cell uses young-leaf value. Table 4 splits SPAD (and Fv/Fm) into “old leaves” and “young leaves” columns, but the schema’s SPAD (aquaponics) column is a single cell. Young-leaf SPAD was chosen as the more standard “current leaf status” reading (consistent with how SPAD is typically reported as a single current value in most vault papers, and because the Results narrative discusses “SPAD value of young leaves” as its primary point of comparison, p.399). Old-leaf SPAD (both systems) and young-leaf SPAD (HYD side) are preserved in each row’s Experimental Remarks and in plant.csv (all four System x age combinations are present there as separate rows). This is a schema-column ambiguity, not a paper-internal contradiction, so it is not severity-tagged.

Judgment call — foliar Fe trial (T2) has two independent Fe inputs. All 8 aquaponic trials receive the same constant root-zone Fe-EDDHA baseline (2 mg/L, biweekly, Methods 2.2) regardless of foliar treatment. T2 (foliar Fe) additionally receives foliar Fe-EDDHA spray on top of that baseline — the only trial where the Iron supplemented (baseline) and Nutrient supplemented (foliar) columns both describe the same element via two different delivery routes. Noted explicitly in T2’s Nutrient supplementedDetails to prevent this being misread as double-counting or as a value conflict.

plant_measurements.csv scope: Table 4’s SPAD (both leaf ages), chlorophyll a, chlorophyll b and carotenoid values were extracted to plant.csv (Category=biochemistry), for both AP and HYD, across all 8 trials (80 rows total: 8 trials x 2 systems x 5 analytes). Fv/Fm (maximal PSII quantum yield, both leaf ages) was excluded from plant.csv — it is a dimensionless fluorescence-efficiency ratio, not a pigment/mineral/microbial/proximate analyte, and does not fit any of the four defined categories, matching the precedent set in mourantianBasilFunctionalGrowth2023 for excluding JIP-test fluorescence parameters. Both Fv/Fm values are preserved narratively in this note and in each trial row’s Experimental Remarks (NO COLUMN). Table 3’s growth biometrics (LFM/SFM/RFM/LDM/SDM/RDM, node number) are vegetative biomass, not tissue analytes, so they were not routed to plant.csv either (same precedent) — they are described narratively above and preserved per-trial in Experimental Remarks (NO COLUMN); Height and Leaf count, which ARE dedicated trials.csv columns, hold the AP-side value only (per the vault convention established in pantanellaAquaponicsHydroponicsProduction2012), with the HYD-side value given in each row’s remarks.

No water panel excluded beyond what’s noted in each row’s remarks — Table 2’s full mineral/physical water panel (alkalinity, hardness, TDS, NaCl%, water K/P/Ca/Fe/Zn/Cu) has no trials.csv column home and does not fit plant_measurements.csv’s plant-analyte scope; both influent and effluent values are preserved in full under NO COLUMN in each trial row’s Experimental Remarks (identical across all 8 rows, since one shared water system feeds all three aquaponic replicate units regardless of which foliar nutrient a given plant received).

Figure-only data, never entered as a cell value (per the never-read-a-figure rule): cluster number/plant (Fig. 2), fruit number/plant (Fig. 3), yield g/plant (Fig. 4), fruit fresh mass g/fruit (Fig. 5) — all four are bar charts with Duncan significance letters and zero numeric values anywhere in the running text or a table, for any of the 16 system x nutrient cells. This means the paper’s own headline result (yield) has no AP/HYD cell value in any of the 8 rows, despite being clearly measured, replicated and statistically analyzed. This is worth flagging explicitly per CLAUDE.md’s instruction to say so when a repeated field is missing across a whole batch: this is the second paper in a row (pastorarbuluEnhancingGrowthYield2025, then this one) where the paper’s central yield result is chart-only and therefore unusable in trials.csv as written. If this keeps recurring, it may be worth reconsidering whether “significant per Duncan letter, magnitude inferable only qualitatively” deserves a distinct cell convention rather than blanket NR.

[not reported]/[unclear] fields, grouped, across all 8 trials:

  • Fish: Fish Category, SGR, feed N, feed K, Total Feed (kg), Fish biomass created (kg), Fish weight gain, Fish trial duration (days) (only “6 months” stated, not convertible to an exact day count without assuming a month length — unlike the fixed 7-day week-to-day conversion SCHEMA.md permits), Water recycle (pump runs continuously, no flow rate stated), Water classification, Daily Water exchange rate, pHOptimal (pH explicitly not adjusted, so no optimal/target value exists to report), FUE AP, FUE HYD, WUE, Tissue nitrate AP/HYD (never assessed — this paper measures fruit/leaf mineral status only qualitatively, “data not shown,” Results 3.3).
  • Plant: Plant Category (tomato never given a categorical label beyond species name), Plants/m2 (8 plants/growth-bed unit stated, bed area in m² never given), Plant fresh weight and Plant dry matter as single per-plant totals (only per-organ LFM/SFM/RFM and LDM/SDM/RDM given; summing to one total would be derivation), Artificial Lighting (not mentioned at all — only the 13h/11h light/dark phase is given, with no statement of whether this is natural daylight, shading, or supplemental lighting).
  • Site: Lat, Long — Rafsanjan, Iran is named as the institution’s location but no coordinates are given anywhere in the paper, and per the prime directive these are not looked up from outside knowledge.

Tags judgment call: Meta/Fish/Carp introduced as a new tag facet — no existing vault paper tags a general “Carp” facet, though lennardComparisonPlantGrowth2019 already uses the more specific Meta/Fish/Grass-Carp. Since this paper is a mixed common/grass/silver carp polyculture (not grass carp alone), a general Meta/Fish/Carp tag was used rather than three separate species-level tags, to avoid over-fragmenting a three-species mixed-stocking trial across three new facets; the species breakdown is preserved in the Fish column and note text. Meta/Region/Middle-East reused (matches the convention already used for other Iran/Gulf-region papers, e.g. abusinSustainableFoodProduction2020, albloushiEffectStockingDensity2018, aljenaidNutrientFilmTechnique2026). Meta/Plant/Tomato reused from pinedapinedaResponseTilapiaTomato2020.

New wikilink targets introduced: H.R. Roosta, M. Hamidpour (no existing author notes found in the vault under these or other spellings). Common carp (Cyprinus carpio), Grass carp (Ctenopharyngodon idella), Silver carp (Hypophthalmichthys molitrix) (no existing species notes found). Reused Tomato (Solanum lycopersicum) exactly as spelled in pinedapinedaResponseTilapiaTomato2020.

Resolves a pending vault citation: pinedapinedaResponseTilapiaTomato2020’s Citations to chase already lists “Roosta, H.R.; Hamidpour, M. (2011)” as a #todo — this note is that paper. That citation entry can be checked off when the vault’s citation-tracking is next reconciled (not done automatically here, since this agent was scoped to only its own three output files).

Two OCR/typesetting artifacts noted (not treated as data problems): “Tape water” for “Tap water” (Methods 2.2) and reflowed/hyphen-broken text in Table 3’s column values on p.400 (e.g. “Plan grown in hydroponic systems were nourished with a nutrient sol[ution]…” — reconstructed from context, no numeric values affected). Table 3 and Table 4 both use Duncan’s-test superscript letter groupings (a, b, ab, a-d, etc.) rather than numeric p-values or SD-only reporting; these were preserved in plant.csv Significance cells exactly as printed, using hyphens for letter ranges (e.g. “a-d” for the source’s “a–d”).

System & Setup

FieldValue
System typeFloating raft system (Introduction p.396; Fig. 1)
Media DetailsPerlite-filled pots (used for 14-day seedling stage), transferred into floating-raft growth-bed units at transplant (Methods 2.2)
Biological system already in useY (Carp stocked and system run continuously for 2.5 months before tomato transplant, to establish and maintain stable nitrifying bacterial populations (Methods 2.1-2.2))
Air supplementY (10 air diffusers (2 L/min each) in each growth bed unit and each fish-rearing tank, cleaned monthly; 3 additional diffusers in the degassing tank (Methods 2.1))
Iron supplementedY (Root-zone baseline (applies to all 8 trials’ AP side, independent of the foliar-nutrient factor): Fe-EDDHA added to aquaponic growth-bed water at 2 mg/L once every two weeks — ‘the only nutrient supplementation in plant growth bed unit of aquaponic systems’ (Methods 2.2). HYD side uses standard complete nutrient solution with 20 uM Fe-EDDHA built into the recipe (not a ‘supplement’ in the added-extra sense).)
RemineralizationN (Methods 2.2 explicitly states Fe was ‘the only nutrient supplementation’ in the aquaponic growth bed — no broader remineralization performed.)
pH BuffersN (‘The pH value of water was not adjusted during the experiment; it was in the range of 7.0-7.7’ (Methods 2.1).)

Experimental Remarks: TRIAL DEFINITION: T1 = untreated control (no foliar spray) — aquaponic (carp-water-fed floating raft) vs hydroponic (complete mineral nutrient solution) comparison, with foliar-nutrient application as the paper’s second crossed factor held at its control level. Paired control = HYD Control (same row, HYD-labelled cells). Design: 2 (system: AP/HYD) x 8 (foliar nutrient: control + 7 elements) factorial in a completely randomized design, 3 replications (independent growth-bed rows/units per system, Methods 2.4, Fig. 1); this trial = the AP-vs-HYD comparison at the ‘no foliar spray’ level of the second factor. | SHARED FISH/WATER DATA (identical across all 8 trials, one shared RAS/aquaponic water source feeds all three replicate aquaponic units regardless of foliar-nutrient sub-treatment; see roostaEffectsFoliarApplication2011-T1 Experimental Remarks for full detail and WARN flags): Common carp/grass carp/silver carp polyculture stocked in 3 identical 848 L rearing tanks (diameter 1.2 m, depth 0.75 m), initial mass range 160-180 g, cultured 6 months total (2.5 months pre-transplant + through the 108-day plant trial). FCR 1.43 (pooled across all three species, Results 3.2, p.398). Survival 100% all species. Mean harvest mass: common carp 473 g, grass carp 414 g, silver carp 387 g (Results 3.2). Production at harvest: common carp 8367, grass carp 9764, silver carp 6846 g/m3 (Results 3.2; NO COLUMN, areal/volumetric production distinct from Fish biomass created). Water quality (Table 2, growth-bed effluent used for Aq pH/DO/EC/Water temperature/TAN/NO2-N/NO3-N cells per SCHEMA’s plant-bed-value rule; growth-bed influent given here for reference): DO 6.03+/-0.06 (effluent) vs 6.10+/-0.06 (influent) mg/L; pH 7.68+/-0.18 (effluent) vs 7.70+/-0.06 (influent); EC 0.51+/-0.01 (effluent) vs 0.54+/-0.02 (influent) [printed unit ‘Ms/cm’ in Table 2, treated as WARN-MINOR typo for mS/cm=dS/m, physically implausible as printed since MS/cm would be many orders of magnitude too high for aquaculture water; values consistent with the paper’s own <1.2 dS/m tolerance-limit column]; Water temp 25.7+/-0.74 (effluent) vs 25.7+/-0.82 (influent) C; NO3-N 34.9+/-2.1 (effluent) vs 34.6+/-3.1 (influent) mg/L; NO2-N 1.57+/-0.30 (effluent) vs 1.69+/-0.32 (influent) mg/L, both exceeding the paper’s own <0.2 mg/L tolerance limit — flagged by the authors themselves (Results 3.1, p.397) as the one out-of-range parameter; NH4-N 0.32+/-0.02 (effluent) vs 0.33+/-0.02 (influent) mg/L. NO COLUMN water panel (Table 2, effluent/influent): Total alkalinity 249+/-62 / 250+/-67 mg/L CaCO3; Total hardness 161.6+/-5.7 / 162+/-12 mg/L; TDS 338+/-24 / 327+/-12 mg/L; NaCl 0.63+/-0.15% / 1.02+/-0.14%; water K 25.9+/-3.2 / 26.7+/-5.2 mg/L; water P 7.50+/-0.43 / 7.98+/-0.59 mg/L; Ca hardness 34.2+/-0.36 / 34.2+/-0.23 mg/L; water Fe 0.21+/-0.03 / 0.21+/-0.02 mg/L; water Zn 0.36+/-0.02 / 0.37+/-0.01 mg/L; water Cu 0.042+/-0.02 / 0.042+/-0.01 mg/L. WARN-MATERIAL Initial Stock density, all three species (Methods 2.1 p.396 vs Results 3.2 p.398): Methods states carp ‘stocked in the rearing tanks…at 15, 20 and 15 fish m-3, respectively’ for common/grass/silver carp. Results 3.2 states ‘Common carp, grass carp and silver carp were stocked at 17.69, 23.58 and 17.69 fish m-3, respectively’ — a different density for all three species, same units, same population. Checked: 15/0.848 m3 (the stated per-tank water volume, Methods 2.1) = 17.69; 20/0.848 = 23.58; 15/0.848 = 17.69 — exact match (2 dp) for all three species, strongly suggesting Methods’ ‘15, 20, 15’ are raw per-tank fish COUNTS mislabelled with a fish/m3 unit, and Results’ values are the correctly computed densities using the tank volume Methods itself states. Recorded Results’ values (17.69, 23.58, 17.69 fish/m3) in the Initial Stock density cell as the defensible reading; Methods’ figures preserved here as the origin of the apparent count-vs-density mislabelling.

Experimental Remarks: TRIAL DEFINITION: T2 = foliar Fe (Fe-EDDHA) spray treatment — aquaponic vs hydroponic comparison at this foliar-nutrient level. Paired control = HYD Fe (same row, HYD-labelled cells) — i.e. the SAME foliar nutrient applied to hydroponic-grown plants, per the paper’s own 2x8 factorial design (system x foliar nutrient), NOT the AP Control (no-spray) row. Design: 2 (system) x 8 (foliar nutrient) factorial, completely randomized, 3 replications (Methods 2.4). NOTE: distinct from the separate, constant root-zone Fe-EDDHA baseline supplementation (2 mg/L biweekly) applied to ALL aquaponic growth beds regardless of foliar treatment (see Iron supplemented columns) — this trial’s aquaponic plants therefore received BOTH the baseline root-zone Fe AND the foliar Fe spray, unlike the other 6 nutrient trials which received baseline root-zone Fe only (no root-zone spray of K/Mn/B/Mg/Zn/Cu). | SHARED FISH/WATER DATA (identical across all 8 trials, one shared RAS/aquaponic water source feeds all three replicate aquaponic units regardless of foliar-nutrient sub-treatment; see roostaEffectsFoliarApplication2011-T1 Experimental Remarks for full detail and WARN flags): Common carp/grass carp/silver carp polyculture stocked in 3 identical 848 L rearing tanks (diameter 1.2 m, depth 0.75 m), initial mass range 160-180 g, cultured 6 months total (2.5 months pre-transplant + through the 108-day plant trial).

Results 3.2 states ‘Common carp, grass carp and silver carp were stocked at 17.69, 23.58 and 17.69 fish m-3, respectively’ — a different density for all three species, same units, same population. Checked: 15/0.848 m3 (the stated per-tank water volume, Methods 2.1) = 17.69; 20/0.848 = 23.58; 15/0.848 = 17.69 — exact match (2 dp) for all three species, strongly suggesting Methods’ ‘15, 20, 15’ are raw per-tank fish COUNTS mislabelled with a fish/m3 unit, and Results’ values are the correctly computed densities using the tank volume Methods itself states. Recorded Results’ values (17.69, 23.58, 17.69 fish/m3) in the Initial Stock density cell as the defensible reading; Methods’ figures preserved here as the origin of the apparent count-vs-density mislabelling.

Experimental Remarks: TRIAL DEFINITION: T4 = foliar Mn (MnSO4.H2O) spray treatment — aquaponic vs hydroponic comparison at this foliar-nutrient level. Paired control = HYD Mn (same row, HYD-labelled cells) — i.e. the SAME foliar nutrient applied to hydroponic-grown plants, per the paper’s own 2x8 factorial design (system x foliar nutrient), NOT the AP Control (no-spray) row. Design: 2 (system) x 8 (foliar nutrient) factorial, completely randomized, 3 replications (Methods 2.4). | SHARED FISH/WATER DATA (identical across all 8 trials, one shared RAS/aquaponic water source feeds all three replicate aquaponic units regardless of foliar-nutrient sub-treatment; see roostaEffectsFoliarApplication2011-T1 Experimental Remarks for full detail and WARN flags): Common carp/grass carp/silver carp polyculture stocked in 3 identical 848 L rearing tanks (diameter 1.2 m, depth 0.75 m), initial mass range 160-180 g, cultured 6 months total (2.5 months pre-transplant + through the 108-day plant trial). FCR 1.43 (pooled across all three species, Results 3.2, p.398). Survival 100% all species. Mean harvest mass: common carp 473 g, grass carp 414 g, silver carp 387 g (Results 3.2). Production at harvest: common carp 8367, grass carp 9764, silver carp 6846 g/m3 (Results 3.2; NO COLUMN, areal/volumetric production distinct from Fish biomass created). Water quality (Table 2, growth-bed effluent used for Aq pH/DO/EC/Water temperature/TAN/NO2-N/NO3-N cells per SCHEMA’s plant-bed-value rule; growth-bed influent given here for reference): DO 6.03+/-0.06 (effluent) vs 6.10+/-0.06 (influent) mg/L; pH 7.68+/-0.18 (effluent) vs 7.70+/-0.06 (influent); EC 0.51+/-0.01 (effluent) vs 0.54+/-0.02 (influent) [printed unit ‘Ms/cm’ in Table 2, treated as WARN-MINOR typo for mS/cm=dS/m, physically implausible as printed since MS/cm would be many orders of magnitude too high for aquaculture water; values consistent with the paper’s own <1.2 dS/m tolerance-limit column]; Water temp 25.7+/-0.74 (effluent) vs 25.7+/-0.82 (influent) C; NO3-N 34.9+/-2.1 (effluent) vs 34.6+/-3.1 (influent) mg/L; NO2-N 1.57+/-0.30 (effluent) vs 1.69+/-0.32 (influent) mg/L, both exceeding the paper’s own <0.2 mg/L tolerance limit — flagged by the authors themselves (Results 3.1, p.397) as the one out-of-range parameter; NH4-N 0.32+/-0.02 (effluent) vs 0.33+/-0.02 (influent) mg/L. NO COLUMN water panel (Table 2, effluent/influent): Total alkalinity 249+/-62 / 250+/-67 mg/L CaCO3; Total hardness 161.6+/-5.7 / 162+/-12 mg/L; TDS 338+/-24 / 327+/-12 mg/L; NaCl 0.63+/-0.15% / 1.02+/-0.14%; water K 25.9+/-3.2 / 26.7+/-5.2 mg/L; water P 7.50+/-0.43 / 7.98+/-0.59 mg/L; Ca hardness 34.2+/-0.36 / 34.2+/-0.23 mg/L; water Fe 0.21+/-0.03 / 0.21+/-0.02 mg/L; water Zn 0.36+/-0.02 / 0.37+/-0.01 mg/L; water Cu 0.042+/-0.02 / 0.042+/-0.01 mg/L. WARN-MATERIAL Initial Stock density, all three species (Methods 2.1 p.396 vs Results 3.2 p.398): Methods states carp ‘stocked in the rearing tanks…at 15, 20 and 15 fish m-3, respectively’ for common/grass/silver carp. Results 3.2 states ‘Common carp, grass carp and silver carp were stocked at 17.69, 23.58 and 17.69 fish m-3, respectively’ — a different density for all three species, same units, same population. Checked: 15/0.848 m3 (the stated per-tank water volume, Methods 2.1) = 17.69; 20/0.848 = 23.58; 15/0.848 = 17.69 — exact match (2 dp) for all three species, strongly suggesting Methods’ ‘15, 20, 15’ are raw per-tank fish COUNTS mislabelled with a fish/m3 unit, and Results’ values are the correctly computed densities using the tank volume Methods itself states. Recorded Results’ values (17.69, 23.58, 17.69 fish/m3) in the Initial Stock density cell as the defensible reading; Methods’ figures preserved here as the origin of the apparent count-vs-density mislabelling.

System & Setup

FieldValue
System typeFloating raft system (Introduction p.396; Fig. 1)
Media DetailsPerlite-filled pots (used for 14-day seedling stage), transferred into floating-raft growth-bed units at transplant (Methods 2.2)
Biological system already in useY (Carp stocked and system run continuously for 2.5 months before tomato transplant, to establish and maintain stable nitrifying bacterial populations (Methods 2.1-2.2))
Air supplementY (10 air diffusers (2 L/min each) in each growth bed unit and each fish-rearing tank, cleaned monthly; 3 additional diffusers in the degassing tank (Methods 2.1))
Iron supplementedY (Root-zone baseline (applies to all 8 trials’ AP side, independent of the foliar-nutrient factor): Fe-EDDHA added to aquaponic growth-bed water at 2 mg/L once every two weeks — ‘the only nutrient supplementation in plant growth bed unit of aquaponic systems’ (Methods 2.2). HYD side uses standard complete nutrient solution with 20 uM Fe-EDDHA built into the recipe (not a ‘supplement’ in the added-extra sense).)
RemineralizationN (Methods 2.2 explicitly states Fe was ‘the only nutrient supplementation’ in the aquaponic growth bed — no broader remineralization performed.)
pH BuffersN (‘The pH value of water was not adjusted during the experiment; it was in the range of 7.0-7.7’ (Methods 2.1).)
Climate controlY (Greenhouse cooled with central cooler supplying cool air; 13h light phase 26+/-3C, 11h dark phase 22+/-3C; RH 52.4-63.2% (Methods 2.2))
Nutrient supplementedY (Foliar spray of H3BO3 (0.5 g/L, 250 mL/plant), applied twice/month beginning 30 days after transplant, continuing through the 108-day trial (Methods 2.2). Applied identically to both AP- and HYD-grown plants in this row (foliar spray is independent of growing-system water source).)
EquipmentSPAD-502 Chlorophyll Meter (Minolta Camera Co. Ltd., Japan); Plant Efficiency Analyzer Handy PEA (Hansatech Instruments Ltd., Norfolk, UK); standard methods for pH/alkalinity/TDS/TAN/NO2-N/NO3-N/DO/water temperature (specific instrument models not stated, Methods 2.3)
Control ParametersGreenhouse 13h light (26+/-3C)/11h dark (22+/-3C); RH 52.4-63.2%; aquaponic water pH unadjusted, ranged 7.0-7.7; DO tolerance >6 mg/L, EC<1.2 (dS/m), NO2-N<0.2 mg/L, NO3-N<150 mg/L, pH 7-8 (Table 2 tolerance limits, citing Graber and Junge 2009; Boyd 1992; Boyd and Tucker 1998)

System & Setup

FieldValue
System typeFloating raft system (Introduction p.396; Fig. 1)
Media DetailsPerlite-filled pots (used for 14-day seedling stage), transferred into floating-raft growth-bed units at transplant (Methods 2.2)
Biological system already in useY (Carp stocked and system run continuously for 2.5 months before tomato transplant, to establish and maintain stable nitrifying bacterial populations (Methods 2.1-2.2))
Air supplementY (10 air diffusers (2 L/min each) in each growth bed unit and each fish-rearing tank, cleaned monthly; 3 additional diffusers in the degassing tank (Methods 2.1))
Iron supplementedY (Root-zone baseline (applies to all 8 trials’ AP side, independent of the foliar-nutrient factor): Fe-EDDHA added to aquaponic growth-bed water at 2 mg/L once every two weeks — ‘the only nutrient supplementation in plant growth bed unit of aquaponic systems’ (Methods 2.2). HYD side uses standard complete nutrient solution with 20 uM Fe-EDDHA built into the recipe (not a ‘supplement’ in the added-extra sense).)
RemineralizationN (Methods 2.2 explicitly states Fe was ‘the only nutrient supplementation’ in the aquaponic growth bed — no broader remineralization performed.)
pH BuffersN (‘The pH value of water was not adjusted during the experiment; it was in the range of 7.0-7.7’ (Methods 2.1).)
Climate controlY (Greenhouse cooled with central cooler supplying cool air; 13h light phase 26+/-3C, 11h dark phase 22+/-3C; RH 52.4-63.2% (Methods 2.2))
Nutrient supplementedY (Foliar spray of MgSO4.7H2O (0.5 g/L, 250 mL/plant), applied twice/month beginning 30 days after transplant, continuing through the 108-day trial (Methods 2.2). Applied identically to both AP- and HYD-grown plants in this row (foliar spray is independent of growing-system water source).)
EquipmentSPAD-502 Chlorophyll Meter (Minolta Camera Co. Ltd., Japan); Plant Efficiency Analyzer Handy PEA (Hansatech Instruments Ltd., Norfolk, UK); standard methods for pH/alkalinity/TDS/TAN/NO2-N/NO3-N/DO/water temperature (specific instrument models not stated, Methods 2.3)
Control ParametersGreenhouse 13h light (26+/-3C)/11h dark (22+/-3C); RH 52.4-63.2%; aquaponic water pH unadjusted, ranged 7.0-7.7; DO tolerance >6 mg/L, EC<1.2 (dS/m), NO2-N<0.2 mg/L, NO3-N<150 mg/L, pH 7-8 (Table 2 tolerance limits, citing Graber and Junge 2009; Boyd 1992; Boyd and Tucker 1998)

Experimental Remarks: TRIAL DEFINITION: T6 = foliar Mg (MgSO4.7H2O) spray treatment — aquaponic vs hydroponic comparison at this foliar-nutrient level. Paired control = HYD Mg (same row, HYD-labelled cells) — i.e. the SAME foliar nutrient applied to hydroponic-grown plants, per the paper’s own 2x8 factorial design (system x foliar nutrient), NOT the AP Control (no-spray) row. Design: 2 (system) x 8 (foliar nutrient) factorial, completely randomized, 3 replications (Methods 2.4). | SHARED FISH/WATER DATA (identical across all 8 trials, one shared RAS/aquaponic water source feeds all three replicate aquaponic units regardless of foliar-nutrient sub-treatment; see roostaEffectsFoliarApplication2011-T1 Experimental Remarks for full detail and WARN flags): Common carp/grass carp/silver carp polyculture stocked in 3 identical 848 L rearing tanks (diameter 1.2 m, depth 0.75 m), initial mass range 160-180 g, cultured 6 months total (2.5 months pre-transplant + through the 108-day plant trial). FCR 1.43 (pooled across all three species, Results 3.2, p.398). Survival 100% all species. Mean harvest mass: common carp 473 g, grass carp 414 g, silver carp 387 g (Results 3.2). Production at harvest: common carp 8367, grass carp 9764, silver carp 6846 g/m3 (Results 3.2; NO COLUMN, areal/volumetric production distinct from Fish biomass created). Water quality (Table 2, growth-bed effluent used for Aq pH/DO/EC/Water temperature/TAN/NO2-N/NO3-N cells per SCHEMA’s plant-bed-value rule; growth-bed influent given here for reference): DO 6.03+/-0.06 (effluent) vs 6.10+/-0.06 (influent) mg/L; pH 7.68+/-0.18 (effluent) vs 7.70+/-0.06 (influent); EC 0.51+/-0.01 (effluent) vs 0.54+/-0.02 (influent) [printed unit ‘Ms/cm’ in Table 2, treated as WARN-MINOR typo for mS/cm=dS/m, physically implausible as printed since MS/cm would be many orders of magnitude too high for aquaculture water; values consistent with the paper’s own <1.2 dS/m tolerance-limit column]; Water temp 25.7+/-0.74 (effluent) vs 25.7+/-0.82 (influent) C; NO3-N 34.9+/-2.1 (effluent) vs 34.6+/-3.1 (influent) mg/L; NO2-N 1.57+/-0.30 (effluent) vs 1.69+/-0.32 (influent) mg/L, both exceeding the paper’s own <0.2 mg/L tolerance limit — flagged by the authors themselves (Results 3.1, p.397) as the one out-of-range parameter; NH4-N 0.32+/-0.02 (effluent) vs 0.33+/-0.02 (influent) mg/L.

WARN-MATERIAL Initial Stock density, all three species (Methods 2.1 p.396 vs Results 3.2 p.398): Methods states carp ‘stocked in the rearing tanks…at 15, 20 and 15 fish m-3, respectively’ for common/grass/silver carp. Results 3.2 states ‘Common carp, grass carp and silver carp were stocked at 17.69, 23.58 and 17.69 fish m-3, respectively’ — a different density for all three species, same units, same population. Checked: 15/0.848 m3 (the stated per-tank water volume, Methods 2.1) = 17.69; 20/0.848 = 23.58; 15/0.848 = 17.69 — exact match (2 dp) for all three species, strongly suggesting Methods’ ‘15, 20, 15’ are raw per-tank fish COUNTS mislabelled with a fish/m3 unit, and Results’ values are the correctly computed densities using the tank volume Methods itself states. Recorded Results’ values (17.69, 23.58, 17.69 fish/m3) in the Initial Stock density cell as the defensible reading; Methods’ figures preserved here as the origin of the apparent count-vs-density mislabelling.

System & Setup

FieldValue
System typeFloating raft system (Introduction p.396; Fig. 1)
Media DetailsPerlite-filled pots (used for 14-day seedling stage), transferred into floating-raft growth-bed units at transplant (Methods 2.2)
Biological system already in useY (Carp stocked and system run continuously for 2.5 months before tomato transplant, to establish and maintain stable nitrifying bacterial populations (Methods 2.1-2.2))
Air supplementY (10 air diffusers (2 L/min each) in each growth bed unit and each fish-rearing tank, cleaned monthly; 3 additional diffusers in the degassing tank (Methods 2.1))
Iron supplementedY (Root-zone baseline (applies to all 8 trials’ AP side, independent of the foliar-nutrient factor): Fe-EDDHA added to aquaponic growth-bed water at 2 mg/L once every two weeks — ‘the only nutrient supplementation in plant growth bed unit of aquaponic systems’ (Methods 2.2). HYD side uses standard complete nutrient solution with 20 uM Fe-EDDHA built into the recipe (not a ‘supplement’ in the added-extra sense).)
RemineralizationN (Methods 2.2 explicitly states Fe was ‘the only nutrient supplementation’ in the aquaponic growth bed — no broader remineralization performed.)
pH BuffersN (‘The pH value of water was not adjusted during the experiment; it was in the range of 7.0-7.7’ (Methods 2.1).)
Climate controlY (Greenhouse cooled with central cooler supplying cool air; 13h light phase 26+/-3C, 11h dark phase 22+/-3C; RH 52.4-63.2% (Methods 2.2))
Nutrient supplementedY (Foliar spray of CuSO4.5H2O (0.5 g/L, 250 mL/plant), applied twice/month beginning 30 days after transplant, continuing through the 108-day trial (Methods 2.2). Applied identically to both AP- and HYD-grown plants in this row (foliar spray is independent of growing-system water source).)
EquipmentSPAD-502 Chlorophyll Meter (Minolta Camera Co. Ltd., Japan); Plant Efficiency Analyzer Handy PEA (Hansatech Instruments Ltd., Norfolk, UK); standard methods for pH/alkalinity/TDS/TAN/NO2-N/NO3-N/DO/water temperature (specific instrument models not stated, Methods 2.3)
Control ParametersGreenhouse 13h light (26+/-3C)/11h dark (22+/-3C); RH 52.4-63.2%; aquaponic water pH unadjusted, ranged 7.0-7.7; DO tolerance >6 mg/L, EC<1.2 (dS/m), NO2-N<0.2 mg/L, NO3-N<150 mg/L, pH 7-8 (Table 2 tolerance limits, citing Graber and Junge 2009; Boyd 1992; Boyd and Tucker 1998)
CombinationCommon carp/grass carp/silver carp polyculture and tomato (floating raft) in a coupled aquaponic system vs. hydroponic control; this row = foliar Cu treatment, tested identically on AP- and HYD-grown plants within the paper’s 2x8 factorial design (Methods 2.4)

Experimental Remarks: TRIAL DEFINITION: T8 = foliar Cu (CuSO4.5H2O) spray treatment — aquaponic vs hydroponic comparison at this foliar-nutrient level. Paired control = HYD Cu (same row, HYD-labelled cells) — i.e. the SAME foliar nutrient applied to hydroponic-grown plants, per the paper’s own 2x8 factorial design (system x foliar nutrient), NOT the AP Control (no-spray) row. Design: 2 (system) x 8 (foliar nutrient) factorial, completely randomized, 3 replications (Methods 2.4). | SHARED FISH/WATER DATA (identical across all 8 trials, one shared RAS/aquaponic water source feeds all three replicate aquaponic units regardless of foliar-nutrient sub-treatment; see roostaEffectsFoliarApplication2011-T1 Experimental Remarks for full detail and WARN flags): Common carp/grass carp/silver carp polyculture stocked in 3 identical 848 L rearing tanks (diameter 1.2 m, depth 0.75 m), initial mass range 160-180 g, cultured 6 months total (2.5 months pre-transplant + through the 108-day plant trial). FCR 1.43 (pooled across all three species, Results 3.2, p.398). Survival 100% all species. Mean harvest mass: common carp 473 g, grass carp 414 g, silver carp 387 g (Results 3.2). Production at harvest: common carp 8367, grass carp 9764, silver carp 6846 g/m3 (Results 3.2; NO COLUMN, areal/volumetric production distinct from Fish biomass created). Water quality (Table 2, growth-bed effluent used for Aq pH/DO/EC/Water temperature/TAN/NO2-N/NO3-N cells per SCHEMA’s plant-bed-value rule; growth-bed influent given here for reference): DO 6.03+/-0.06 (effluent) vs 6.10+/-0.06 (influent) mg/L; pH 7.68+/-0.18 (effluent) vs 7.70+/-0.06 (influent); EC 0.51+/-0.01 (effluent) vs 0.54+/-0.02 (influent) [printed unit ‘Ms/cm’ in Table 2, treated as WARN-MINOR typo for mS/cm=dS/m, physically implausible as printed since MS/cm would be many orders of magnitude too high for aquaculture water; values consistent with the paper’s own <1.2 dS/m tolerance-limit column]; Water temp 25.7+/-0.74 (effluent) vs 25.7+/-0.82 (influent) C; NO3-N 34.9+/-2.1 (effluent) vs 34.6+/-3.1 (influent) mg/L; NO2-N 1.57+/-0.30 (effluent) vs 1.69+/-0.32 (influent) mg/L, both exceeding the paper’s own <0.2 mg/L tolerance limit — flagged by the authors themselves (Results 3.1, p.397) as the one out-of-range parameter; NH4-N 0.32+/-0.02 (effluent) vs 0.33+/-0.02 (influent) mg/L.

WARN-MATERIAL Initial Stock density, all three species (Methods 2.1 p.396 vs Results 3.2 p.398): Methods states carp ‘stocked in the rearing tanks…at 15, 20 and 15 fish m-3, respectively’ for common/grass/silver carp. Results 3.2 states ‘Common carp, grass carp and silver carp were stocked at 17.69, 23.58 and 17.69 fish m-3, respectively’ — a different density for all three species, same units, same population. Checked: 15/0.848 m3 (the stated per-tank water volume, Methods 2.1) = 17.69; 20/0.848 = 23.58; 15/0.848 = 17.69 — exact match (2 dp) for all three species, strongly suggesting Methods’ ‘15, 20, 15’ are raw per-tank fish COUNTS mislabelled with a fish/m3 unit, and Results’ values are the correctly computed densities using the tank volume Methods itself states. Recorded Results’ values (17.69, 23.58, 17.69 fish/m3) in the Initial Stock density cell as the defensible reading; Methods’ figures preserved here as the origin of the apparent count-vs-density mislabelling.
