Present study is aimed to determine the feed formulation, with optimum protein level using locally available economic protein
sources, in order to achieve the better growth of the fish and was conducted in four different earthen ponds to observe the
effect of varying protein sources (jawar and ground nut oil cake) and protein levels of supplementary feed (28% to 40%) on the
growth performance of
fed on 5% body weight per day for 180 days. After preliminary preparation of the ponds,
fingerlings of Rohu (25?2 gm, 10?1.2 cm) were stocked (12500 fingerlings per hectare) in the month of March for year 2011 and
2012. Four different diets were prepared by using fish meal, jawar, soya bean, groundnut oil cake, wheat, rice bran and millet.
Highest growth was observed for the fingerlings which were fed on 34% protein rich diet. ALWG, SGR and fish muscle protein
increased and FCR decreased with increasing dietary protein level up to 34%. Growth performance of fingerlings fed on 28%
protein rich diet using ground nut oil cake was recorded high. Phosphate, total Kjeldhal nitrogen, ammonia, alkalinity and
planktonic population in the pond water increased with increase in dietary protein. Fish production, cost of inputs and net profit
were calculated and maximum profit was recorded from 34% protein rich diet, hence present findings will benefit fish farmers,
fish feed industrialists and consumers
