ABSTRACT
The rearing of larval stages of marine fishes beyond the yolk sac absorption stage for cultivation is carried out using live or artificial feeds. Live food organisms are used for the majority of species that are of interest as cultivation candidates, but provision of a sufficient supply of these organisms to a culture system presents many problems. These problems, along with the advantages and disadvantages of using live food organisms, are discussed. The desire to substitute artificial diets for live food organisms in culturing marine larvae has been expressed in the literature and some success has been achieved. The small size and extent of development of larvae at the completion of yolk sac absorption is thought to be the main hindrance to greater success with these diets. The appropriate feed technology and nutritional requirement information for these larval stages must be provided in order to facilitate the transition to artificial diets.
