Author(s): Prianka Paul, Md. Anisur Rahman
Abstract: The effect of five different supplementary feeds on growth, survival and production were investigated for juveniles of
Macrobrachium rosenbergii. The best growth was obtained with the feed containing 31.50% dietary protein. Feed conversion ratio decreased with increasing weight of prawn and is negatively correlated with dietary protein level. The highest average weight gain (48.03g) of prawn was found in treatment T
1. The mean survival rates were found at 86.46, 81.33, 75.33, and 79.44 and 78.33% in T
1, T
2, T
3, T
4 and T
5 treatments, respectively. The comparable net production of freshwater prawn was (166.14kg/bigha) significantly higher (
P≤0.05) in treatment T
1 among all the treatments. The feed conversion ratio was the lowest (1.13) and specific growth rate was the highest (2.19%) found in treatment T
1.Considering all facts, the better growth performance was recorded in treatment T
1 compared to other treatments T
2, T
3, T
4 and T
5.
