Assessment of the comparative growth performance of Tilapia (Oreochromis niloticus) at different stocking densities.
Journal Title: International Journal of Biological Innovations - Year 2022, Vol 4, Issue 1
Abstract
This study was intended to assess the comparative growth and production performance in relation to different stocking densities to have better understanding on the consecutive growth 3 trends. Tilapia (Oreochromis niloticus) fry was released at the rate of 8 fry per tank (1m ) as per the recommended stocking density of 320 fishes/decimal and 4 fry per tank equivalent to the stocking density of 160 fishes/decimal in intensive (T ) and semi-intensive (T ) aquaculture system, 1 2 respectively. Floating feed was used to evaluate the growth performance during the experimental period for T and T , respectively. There were six replications for each treatment. The feed was 1 2 supplied at the rate of 20%, 15%, and 10% of the body weight during the study period of 90 days. The weight gains of fish were 132.23±1.29 and 63.12±4.97g for T and T respectively. Feed conversion 1 2, ratio (FCR) in T and T were 2.43±0.18 and 2.13±0.20, respectively. Higher total production was 1 2 obtained in T (1119.52 g) than T (830.96 g) with 100% survival in both the treatments. The present 1 2 study indicates that, the production performance acquired higher in T having significant difference 1 compared to T and the intensive culture of Tilapia is more rational for getting more production in 2 relation to semi-intensive culture.
