Chironomus larvae culture ?A boon to Aquaculture sector

The C.ramosus larvae were selected for the present study. Four types of organic nutrient manure were prepared viz; cow dung, vegetable waste, duck waste and rice bran. Each organic manure weight range from 5, 10,15g dissolved in 10 lt of dechlorinated water. Among the organic manure the cow dung (15) g displayed the following parameters, no of eggs was 286.66 ±1.24,Hatchability 96.66±4.71 and the fly emergence is 15.0 ±0.816 days, survival rate was 100% and followed other organic manure. Due to the organic manure variation, the larval periods also ranged from 14-19 days were observed. The life cycle of the species 23 days were recorded respectively.
