    Larval nutrition is an important part of the hatchery operation. Successful larval rearing primarily depends on the live feed and zooplankton forms the most important component in the live feed. Larval feed should be smaller, easily digestible, rich in nutrients and allow autolysis. Formulated feed may not meet all these requirements and in most of the cases this will reduce the larval survival rate than live food. Moreover, the fish larvae have poor vision and less developed olfactory and digestive organs. The size of feed is important when the mouth size of larvae is concerned. Poor vision, improper digestive system and weaker movements make it difficult for the larvae to get proper nourishment. Some fish larvae (precautionary type) are with good yolk reserve and they start feeding at a comparatively developed stage while some others (atresial type) start feeding at smaller size and lesser developed stage. Salmon, cobia and clown fish larvae are comparatively larger than grouper and damsel larvae.
