The cyclops are important live feed in aquaculture. Cyclops sp. is rich in proteins, unsaturated fatty acids, polyunsaturated fatty acids, carotenoids and other essential nutrients bust lacks some essential nutrients. The nutritive value of cyclops enhanced with the help of enrichment process. Firstly, algal strain culture at control temperature (25o C), salinity (30ppt), then mixed with cyclops live feed. Cyclops enriched at temp (17 ? 20 o C), salinity (30g/L), and DO (5 ? 6 ppm). Enriched cyclops are fed to larval fish. In this article, discuss about how to algal strain culture, cyclops enrichment and feeding to larvae and their impact on fish larvae.
