Manipuri are very fond of fish so rearing fish is one of the profitable agricultural practice and many farms are continuously developed. The huge production from lakes and river farming are much lagging behind the requirements of the state. Shortage of nutrient rich fish diet is one of main cause of shortage of fish production in Manipur. Keeping this aim in mind, the present study was taken up to enrich the fish diet using easily available Chironomus species larvae as source of nutrient. Two species of the Chironomus species: C. plumosus and DSC 1(predominant species foundly in polluted habitats and yet to identify), were compared on basis of nutrient contents like carbohydrate, fats, proteins, omega 3 etc. Larvae of same species were collected from seven aquatic habitats. The larvae were dried in the room temperature in the shade. Then the dried larvae were grinded into powder and outsourced for the nutrient testing. Besides the nutrients study the materials were tested for presence of unwanted/harmful metals that might be accumulated from the environments of the larvae. The results showed that the larvae possessed roughly equal amount of nutrients despite differences in size of the larvae and there were no reports of presence of unwanted/harmful metals that might accumulate from the diet to the fish. So, they are safe as artificial fish diet. Moreover, the larvae contain fair amount of omega 3 which is good for value added fishery. But it is yet to be tested whether the omegas that were present in the larval diet will be transferring to the fish and again reached the general mass. Future studies should focus on the mass production of the larvae including the adults for sustainable generation of different development stages for mass production.
