Although dietary phospholipids (PL) and particularly phosphatidylcholine (PC) have been found to enhance growth and survival in penaeid shrimp, precise requirements have yet to be established. Substantially variable responses of feeding PL have been noticed in crustaceans in relation to the growth stage of the animals and the composition of the other dietary ingredients. In several shrimp feeding trials phospholipids of unspecified composition, have been used, such as crude lecithin, as a result of which it is difficult to draw conclusions with regard to the optimal levels/types of dietary PL required by penaeid shrimp. This paper is part of a broad study which aims to assess the dietary effect of different levels/types of purified PL in marine fish and penaeid shrimp and reports on the results of a preliminar feeding trial with postlarvae of Penaeus japonicus using purified soya-PC in a semi-purified diet.
