Labeo rohita by incorporating at inclusion levels of 10%, 20% and 30%, respectively.
Fish meal based diet served as the control. Diet containing 30% of soyabean meal
(30%SM) was devoid of fish meal. The overall protein content of the diets was 30%.
The study was conducted for a period of 126 days in circular cement cisterns of 350 litre
capacity; feeding being done at the rate 5% of the body weight Best growth of rohu
was attained on 20% SM diet, followed by lOOiO SM, control and 30% SM. The 30%
SM diet was the most stable and the control diet showed the least stability. Fish fed
30% SM diet recorded the lowest average weight on termination of the experiment
which was also reflected in the FCE and nutrient digestibility. The inclusion level of
soyabean meal was found to influence the carcass composition and enzyme profile.
Survival was not affected by soyabean meal incorporation; production was found related
to growth rather than survival. Organoleptic quality of fish was not affected adversely
by soyabean meal incorporation in the diet.
