ABSTRACT
The nutrition of the larval stages of marine fish is the principle factor affecting their growth and survival. Basically, a food particle has to support the larval nutritional requirements from the point of view of larval nutrients and energy supply. These can be supplied to the larva through both live and inert feeds. Among the properties of these feeds, which are relevant to the larval nutrition, attractability, motility and reduced effects on water quality in the rearing tanks make live feeds advantageous over inert diets. On the other hand, control of chemical composition and size, in addition to managemental properties such as price and availability, with no seasonality, make inert diets a replacement of live feeds. However, technological advances are still required to enable better use of the potential of the dry diets. This paper discusses the merits of live and dry feeds and proposes a pathway for a gradual transfer to inert diets.
