Effect of stocking density on growth performance, gross energy, proximate analysis of meat, and stress response of mahseer ( <i>Tor soro</i> ) fry
. The experiment was conducted in a completely randomized design with varying stocking density levels, namely one fish/L, two fish/L, three fish/L, and four fish/L as treatment, with four replicates each. Findings indicate that different stocking densities had a significant effect on the aforementioned growth-related parameter where the stocking density of one fish/L showed the highest weight gain (4.36 ± 0.42 grams), the fastest daily growth rate (1.17 ± 0.09% per day), the highest gross energy value (2,151 kcal/g), the most efficient feed conversion ratio or FCR (1.76 ± 0.13), the lowest cortisol levels (6.06 ± 0.19 ng/ml), and the lowest superoxide dismutase (SOD) levels (3.50 ± 0.89 ng/mg), compared to the other treatments. These results indicate that a stocking density of one individual/L was the optimal density for mahseer seed rearing in culture containers.
