“…Abiotic parameters have a definite role in the growth of fish [61]. Identification of critical water quality parameters affecting fish growth is of prime requirement in enclosure culture systems [62]. In the present experiment, fish growth was found to have a statistically significant positive correlation with water temperature and total alkalinity.…”

Labeo bata fry were reared in high-density polyethylene (HDPE) pens at different stocking densities to determine growth, survival, feed utilization efficiency and economics in Borkona beel, Barpeta, Assam. Pens (500 m2 each) were stocked with fry at four stocking densities, 3 (SD3), 5 (SD5), 7 (SD7) and 9 (SD9) no. m−2 in triplicates. Feeding was performed twice a day at a rate of 3–5% body weight with floating pelleted feed containing 28% crude protein. Fish grew from 2.38 ± 0.30 g to 82.78 ± 3.18, 75.94 ± 0.89, 71.94 ± 0.89 and 61.81 ± 3.35 g at stocking densities of 3, 5, 7 and 9 no. m−2, respectively. Weight gain per cent ranged from 2491.85 ± 140.56 to 3371.33 ± 133.16 and specific growth rate from 1.41 ± 0.02 to 1.55 ± 0.02, both of which decreased with increasing stocking density. The net and gross yields increased with increasing stocking density and were highest at SD9. The benefit-cost ratio was maximum at SD7 (1.42), followed by SD9 (1.41). Post-pen culture, the monthly income of fishers increased by 6.10% (SD3) to 40.50% (SD9). Significant differences (p > 0.05) in water quality parameters were not observed between treatments (inside pens) and reference site (outside pen at 10 m distance). Weight gain exhibited a significant positive correlation with temperature (r = 0.92; p = 0.029) and alkalinity (r = 0.95; p = 0.014). The present study can provide impetus towards species diversification in pen enclosures, income enhancement of small-scale wetland fishers and sustainable ecosystem-based floodplain wetland fisheries management.

“…In general, where fishing takes considerable time and effort and is often riddled with uncertainties, enclosure culture in these water bodies provides fishers with the option of stock protection, besides easy and certain harvest 157 . Considering the advantages, possibilities supported by recent technological advancements and standardized culture protocols, 158–160 adoption of enclosure culture has been noticed in inland water bodies of the country in recent years. The states of Jharkhand and Tamil Nadu have been on the forefront in propagating cage culture in reservoirs 161 .…”

“…O. pabda is better suited to alternative methods with higher production e ciency and pro t margins (De Schryver et al 2008). Hitherto, O. pabda farming in semi-intensive management (Kohinoor et al 2018), in cemented dewatering canal (Nahar et al 2019), and cages (Karnatak et al 2021) and in earthen ponds (Samad et al 2018) with different stocking densities have been reported; nevertheless, good stocking density in a BFT system is still not well established, particularly in local environmental condition, and thus more studies are necessary for adopting BFT system for this species.…”

Biofloc technology (BFT) is nowadays considered as eco-friendly approach being used for fish and shellfish production. The present investigation aimed at comparing water quality, as well as immune responses, nutritional condition and production of Ompok pabda between the traditional culture system with stocking density of 17 (TS1), 22 (TS2) and BFT system (C: N ratio of 20:1; molasses as carbon source) with 17 (BFTS1), 22 (BFTS2), 27 (BFTS3) fish of 0.30 ± 0.001 g/m2; the fishes were reared with feeding a commercial diet at 10 − 3% of their body weight for 90 days in tanks. There was significant (p < 0.05) variation in water quality parameters including dissolved oxygen, pH, total ammonia nitrogen (TAN) between the traditional and BFT tanks. The fishes of the BFTS1 had the highest specific growth rate (SGR, 4.11 ± 0.17%/day) and survival (98.33 ± 2.89%) while the TS2 had the lowest SGR (3.51 ± 0.05) and survival (86.67 ± 5.03%). The protein, lipid, essential amino acids, monounsaturated fatty acid and polyunsaturated fatty acid contents were found higher in the BFT-reared fishes compared to the TS-reared fishes. The fishes of the BFT system had also higher red blood cell (3.28x106/mm3), hematocrit (34.5%), and neutrophil counts (27.30%) than had the TS-reared fishes. Regarding profitability, the BFTS2 provided the highest benefit-cost ratio (BCR; 1.22 ± 0.04) whereas the TS1 system had the lowest BCR (0.99 ± 0.04). Altogether, the obtained results points out that the stocking density modulated the rearing environment, and thus, production of O. pabda traditional and BFT systems; considering FCR and BCR values, the stocking density of 22 fish/m2 can be feasible to bring about good economic return of a O. pabda biofloc system.
