Effect of feeding on growth performance, survival and production of carp in net partition system in canal of Sundarbans, India

Abstract

A study was conducted to investigate the effect of different feeding percentage on the growth performance and survival of stocked fishes in net partition system at Bharua canal of Sundarbans. The fingerlings of Labeo catla, Labeo rohita and Ctenopharyngodon idella were stocked in three net screen partition systems @2 nos. m-2 at the stocking ratio of 50: 40: 10 and fed with three feeding rate (% body weight) 0% (T1), 2% (T2) and 4% (T3) twice a day (10.00 hrs. and 16.00 hrs.) for 180 days. The result showed that the fishes in fed group (T2 & T3) achieved significantly (p<0.05) higher growth than the non fed treatment (T1). The minimum feeding rate of 2% body weight appeared to be optimal to support the satisfactory growth with low FCR and high feeding efficiency for the culture of Indian major carps and exotic carp in canal system of Sundarbans.
