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.
