Feeding of some fish larvae as determined by prey characteristics

Abstract

Fish larvae generally feed on all the cultured organisms, with preference for particular organisms at different growth phases. Preferential selection, however, is determined by several factors, VIZ., larval age, gape of mouth of larva, prey visibility, prey density and prey digestibility. of all the food organisms. rotifers form the first food of fish larvae. Among cladocerans, Alona, a small species, is the first to make its appearance in larval gut followed by Cenodaphnia and finally by large-sized prey species.
