“…The low carbohydrate concentration in trash fish may hardly support the denitrification in the FFD pond since not enough electron donors were available. It was documented that pond systems rely on natural processes for purification, including ammonia which is converted to less-toxic nitrate through nitrobacteria and nitromonas, while nitrate is taken up by phytoplankton and macroalgae [51]. Actinobacteria and Firmicutes were found to be positively correlated with pH, ORP and alkalinity in our study.…”

Integrated multi trophic aquaculture (IMTA) improves the production of aquatic animals by promoting nutrient utilization through different tropical levels. Microorganisms play an important role in elements cycling, energy flow and farmed-species health. The aim of this study was to evaluate how feed types, fresh frozen fish diet (FFD) or formulated diet (FD), influence the microbial community diversity and functionality in both water and sediment in a marine IMTA system. Preferable water quality, higher animal yields and higher cost efficiency were achieved in the FD pond. Feed types changed the pond bacterial community distribution, especially in the rearing water. The FFD pond was dominated with Cyanobacteria in the water, which played an important role in nitrogen fixation through photosynthesis due to the high nitrogen input of the frozen fish diet. The high carbohydrate composition in the formulated diet triggered higher metabolic pathways related to carbon and lipid metabolism in the water of the FD pond. Sediment had significantly higher microbial diversity than the rearing water. In sediment, the dominating genus, Sulfurovum and Desulfobulbus, were found to be positively correlated by network analysis, which had similar functionality in sulfur transformation. The relatively higher rates of antibiotic biosynthesis in the FFD sediment might be related to the pathogenic bacteria introduced by the trash fish diet. The difference in microbial community composition and metabolic pathways may be associated with the different pathways for nutrient cycling and animal growth performance. The formulated diet was determined to be more ecologically and economically sustainable than the frozen fish diet for marine IMTA pond systems.

“…The aquaculture industry needs environmentally friendly aquatic ecosystems. Therefore, aquaculture practices must use aquaculture systems that minimize waste loads and increase added value 1,3,38,39 . In fact, the diversification of aquaculture systems with the efficient use of land resources can increase aquaculture production 28,40 .…”

“…Aquaculture activities are responsible for the supply of fish for human consumption. To meet the demand for food from aquaculture production, competition uses natural resources, such as land and water [1][2][3] . Many studies state that aquaculture production depends on many factors, including its species, aquaculture system, technical efficiency, production inputs, and infrastructure [4][5][6] .…”

Background: Giant gourami (Osphronemus goramy, Osphronemidae), belonging to the gurami sago strain, is an important economic fish species that was newly released for domestication in 2018 in Indonesia. The present study aimed to determine the growth, production and feed conversion efficiency of gurami sago strain in different aquaculture systems. Methods: A mean of 240 juveniles were stocked (mean, 54.53 g and 13.88 cm) into concrete ponds, ﬂoating net cages and earthen freshwater ponds (12 m3) with three replicates of each. The juveniles were fed a floating commercial pellet diet containing 30% crude protein and 5% crude lipids. Feed was supplied at 3% of fish biomass per day throughout the 90 days of the experiment. The research was conducted in the area surrounding Lake Maninjau of West Sumatera Province, Indonesia. Results: After 90 days, the mean weight of ﬁsh reared in concrete ponds was 166.86 g, floating net cages was 179.51 g and earthen freshwater ponds was 149.89 g. The mean final biomass was 37.64 kg for concrete ponds, 41.27 kg for floating net cages, and 33.72 kg for earthen freshwater ponds. The specific growth rates (%/day) for concrete ponds, floating net cages and earthen freshwater ponds were 0.67, 0.75 and 0.62, respectively. The feed conversion rates were 1.45 for concrete ponds, 1.30 for floating net cages and 1.87 for earthen freshwater ponds. The net yields (kg mˉ3) were 2.05 for concrete ponds, 2.27 for floating net cages, and 1.73 for earthen freshwater ponds. The exponents (b) of the length–weight relationship were calculated for concrete ponds (1.0146), floating net cages (1.2641), and earthen freshwater ponds (1.0056). Conclusion: The study showed that the growth performance, production and feed conversion efficiency of the gurami sago strain could be considered a new candidate strain for floating net cage aquaculture in the future.

“…Nitrite is the intermediate product of ammonia oxidation to nitrate, which is also toxic, and it is generally desirable with the level being below 0.5 mg/L in fish culture systems (Dauda et al, ; Martins et al, ). In this study, concentrations of nitrite nitrogen in the treatments of LAB strains were all significantly lower ( p < 0.05) than in the control group.…”

“…Effluents from industrialized fish farming contain various organic and inorganic compounds such as ammonium, dissolved organic carbon and organic matter (Crab, Avnimelech, Defoirdt, Bossier, & Verstraete, ; Dauda et al, ). Nitrogen in fish feed is an important constituent element present in the form of protein, in which protein is the most expensive component of fish feeds.…”

To understand the nutrient utilization efficiency and distribution in indoor fish culture system under treatment of probiotics, this study examined water quality and nitrogen budget in turbot Scophthalmus maximus culture system supplemented with four strains of lactic acid bacteria (LAB) isolated from fishery products. The results showed that the concentration of ammonia nitrogen (NH₃‐N) and nitrite nitrogen (NO₂‐N) in LAB treatments were all significantly lower (p < 0.05) than in the control group. The nitrate nitrogen (NO₃‐N) in LAB treatments showed no significant differences (p > 0.05) compared with control group. The fish feed and water exchange accounted for 79.07% and 17.02% of total N input respectively. For N output, the drainage and residual diets in LAB treatment accounted for 24.50%–25.80% and 1.33%–1.60% respectively, and they were significantly lower than in the control group (27.60% and 2.20% respectively). Fish growth and lost N in LAB treatments accounted for 27.10%–30.50% and 11.00%–18.50% respectively, and they were both significantly higher (p < 0.05) than in the control group (22.30% and 5.30% respectively). The results indicated that the indigenous LAB strains were capable of improving fish growth, and reducing NH₃‐N and NO₂‐N level (at concentration of 105 cfu/ml) by directly adding in S. maximus culture water. Moreover, specific strains of LAB may increase nitrogen loss by promoting denitrification process in culture system.
