Growth of Grass Carp Ctenopharyngodon idella Fed on Hybrid Napier Grass (CO-3) Mixed Diet
The study was performed to examine the efficiency of hybrid napier grass (CO-3) mixed diet on growth performance of freshwater fish Ctenopharyngodon idella. Alive grass carp fingerlings were collected from commercial fish farm in Thanjavur from June 2015 to May 2016. Fishes were divided into two groups and acclimated for 7 days before feeding trial. The fishes were fed with control and experimental diet. The growth parameters such ABW, ABL, BWG and SGR were thoroughly studied adopting standard procedure. The result of the study clearly indicates that there was a significant variation in growth of control and experimental fishes. The fish fed with CO-3 grass mixed diet showed elevated level in body weight, body length, weight gain and specific growth rate. This study suggests that the CO-3 grass mixed diet is more suitable for grass carp aquaculture practice.
