A review of conventional and unconventional feeds in fish nutrition was carried out to provide information on supplemental feed and its formulation for effective culture fisheries management. Foods for fry and fingerlings frequently exceed 50% crude protein. As growth rate decreases and fish age, protein levels in diets are decreased accordingly. Technology associated with rearing of live foods is improving rapidly. This is having a positive impact on larval rearing, a frequent bottleneck for commercialization of "new" species. This article reviews live feed for fish larvae, fish foods, fish feed ingredients, some common conventional feed stuff, animal and plant sources of unconventional feeds for culture fish, fish feed formulation and feeding methods to provide more information for the effective management of fish farming.
