The current study's goal was to look at how stocking densities affected Bheda (Nandus nandus) growth and production over the course of a 120-day period. Three treatments were T 1 (20,000 fish ha -1 ), T 2 (30,000 fish ha -1 ), and T 3 (40,000 fish ha -1 ), each with three replicates. Those fishes were fed daily with commercial sinking feed and a live food mixture at 9-3% fish body weight up to harvesting. Temperature, dissolved oxygen, pH, and other water quality indicators were measured every two weeks, along with the growth performance of Bheda fish. T 2 had the highest yield of Bheda (3439.08±207.31 kg ha -1 ), followed by T 3 (3422.78±224.42 kg ha -1 ), and T 1 (3136.62±150.00 kg ha -1 ). The harvesting weight (g), individual weight gain (g), individual percent (%) weight gain (g), SGR (% per day), and survival rate (%) of fish were significantly higher (p<0.05) in T 1 , followed by T 2 and T 3 , respectively, where combined production of fishes was significantly higher at T 2 followed by T 3 and T 1 . Net profit and benefit-cost ratio were significantly higher in T 1 than T 2 and T 3 . Based on the results of this experiment, it can be concluded that stocking density of Bheda fingerlings at the rate of 20,000 fish ha -1 in T 1 showed the highest production performance for profitable pond aquaculture. However, further research on the standardisation of stocking density with economic profitability of this fish at the on-station or on-farm level in ponds may be required before widespread dissemination of this culture technology to farmers, particularly in Bangladesh and elsewhere.

“…According to the study, net profit declined as stocking density increased, which was consistent with Dasuki et al (2013) and Hossain et al (2022). The BCR for every treatment exhibits a significant heterogeneity in density.…”

“…~ 36 ~ Although these authors [19] mention that increasing the density modifies the size of the fish, the health of both the fish and the system increases the use of water and the replacement to maintain a good quality, the sedimentation of organic matter increases and consequently increases mortality and decreases the efficiency of growth and productivity of the system. The same is demonstrated in the work done by Mohamed et al., [20] , Robiul et al., [21] , and Sapkota et al., [22] , where all productive and survival values decrease with increasing planting density. In the case of this experiment with Biofloc, all of the above is not reflected in a great way neither in the growth efficiency of the organisms nor in the productivity of the system because the system used produces a continuously present food biomass on which the fish can feed, in addition to the formation of a heterotrophic bacterial biomass capable of decomposing nitrogenous compounds that can be detrimental to both the water quality of the system and the physiology of the fish.…”

Tilapia Pargo UNAM fry was cultured in five 250 L containers at a salinity of 10 gL -1 and a density of 50, 75, 100, and 125, and their weight and length gain, TCA and TIC, KM and FCA, and ECA were determined. The highest weight (658.45±0.43 g) and length (38.22±0.38 cm), with a gain of 657.28 g and 35.09 cm at the 50 org 250L -1 density. However, the greatest gain in length was for the 50 and 75 org 250L -1 densities (35.09 and 34.53 cm, respectively). The highest TCA was for the 50 org 250 L -1 treatment with 6.26 g day -1 and the highest TIC value was 0.33% daily increment for both the 50 and 75 org 250 L -1 densities. The FCA was between 0.0873-0.1052 and the ECA was between 950.20-1,146.04%. It should be noted that survival in all four treatments was above 96%. In this experiment, it was observed that when passing from the density of 75 org 250 L -1 problems in growth and weight and size gain began to occur.

“…In this study, the water quality variables of cages in the River Dakatia were within reasonable limits for O. niloticus (Ross, 2000). Additionally, the quality parameters, i.e., water temperature, pH, dissolved oxygen, free CO2, total alkalinity, total hardness, ammonia-N, and NO2-N, were more or less similar to the following previous studiesin the River Dakatia, Meghna, Gumti, Titas and Hoara, Bangladesh (Hossain et al, 2022;Ahmed et al, 2014).…”

This study examined the intensification of mono-sex Nile tilapia Oreochromis niloticusaquaculturein riverine net cages installed at the River Dakatia, Roghunathpur, Chandpur. This study performed 120-day cage grow-out trials with densities of 50, 75, and 100 tilapia m-3 under three replications with an average initial weight of 28.92±8.37g per juvenile fish. The monthly water quality parameters (temperature, pH, dissolved oxygen, total alkalinity and hardness, ammonia-N and Nitrite-N) in the cage installation water area of the River Dakatia were found to be suitable for tilapia cage culture. The monthly average weight gain was significantly (p < 0.05) higher in 50 tilapia m-3 stocking density than in the other two stocking densities tested. The mean final weight and specific growth rate were significantly (p < 0.05) higher in 50 tilapia m-3 stocking densitythan the other two stocking densities. Significantly (p < 0.05) higher survival (97.92%) was found in the 50 tilapia m-3 stocking density group and followed by 86.74% and 84.39% in the 75 and 100 tilapia m-3 stocking densities, respectively. Consequently, the monthly relative and specific growth rate and feed conversion ratio were significantly (p < 0.05) higher in 50 tilapia m-3 stocking density fishes for the first, third, and fourth months. Gross production was comparable between 50 and 75 tilapia m-3 stocking densities but was significantly (p < 0.05) better than 100 m-3 stocking density. Net production was significantly (p < 0.05) higher at 50 tilapia m-3 stocking density group than those of 75 and 100 tilapia m-3 stocking densities. The best feed conversion ratio (1.60) was in the 50 tilapia m-3 stocking density group (p < 0.05) than those of 1.87 and 2.44 for the stocking of 75 and 100 tilapia m-3, respectively. Benefit-cost ratio and net profit were significantly (p < 0.05) better at 50 and 75 tilapia m-3 than at 100 tilapia m-3 stocking density. Therefore, considering maximum outputs, benefits, and performances, we recommend stocking density at 50 mono-sex tilapia m-3 for the best growth, cost-effective production, and highest-economic return from 120 days of grow-out net cages in the riverine culture system.
