Abstract
This study work evaluates the efficacy of different plant protein sources as substitutes
to the expensive and costly commercial fish feed on the survival, growth and
development of Cirrhinus mrigala. The experiment was conducted in happas in Central
Fisheries Promotion and conservation center (CFPCC) from October 2021 to January
2022. Cirrhinus mrigala fingerlings were obtained from nursery pond of CFPCC.
Average length of 5.06±0.5cm and average weight of 1.5±0.25gm fishes were selected.
Total six hundred fishes were stocked in 12 happas (50 in each happa). The fishes were
fed with three different plant protein sources like soybean, mustard oil cake, fish meal
and denoted T1, T2 and T3; while T4 was commercial feed. Length and weight of the
fishes were recorded at the interval of every 30 days. There was no significant
difference (P> 0.05) observed in the growth in different treatment groups. However,
Food Conversion Ratio (FCR) was recorded increasing all throughout the experiment.
Conditioning factor (K) were recorded ranging from 0.99 to 1.44 under different
treatments. pH and DO of water were recorded suitable while the water temperature
was slightly lower than optimum for fish growth. Though, overall growth of fingerlings
in different treatments was not encouraging but showed almost the same pattern, so
plant protein can be used as a source of protein in fingerling feed.
