This paper presents the variation in lipid compositions during the larval development of the prawn,Penaeus japonicus. The lipid concentrations were high in the ovaries, decreased to low levels atnauplius and zoea1 stages, and then remained roughly constant during the subsequent stages topost-larva1. The marked decrease in lipid concentrations during the period of ovaries to early zoealstages was mainly due to those in both phospholipids (PL) and triglycerides (TG) which were themajor lipid classes throughout the larval developmental stages. The free sterol concentrations didnot vary notably during the larval development from nauplius to post-larva1. As for total lipids, theproportions of highly unsaturated fatty acids such as 20:5ω3, 22:6ω3, and 20:4ω6 increased duringthe period of ovaries to zoea1 stage, whereas those of saturated and monoene fatty acids, specifically16:0 and 16:1, decreased during the same period. Moreover, the decrease in the proportions of 16:1and 18:1 during the above period was attributable mainly to those in both TG and PL, but theincrease in the proportion of 20:5ω3 and 22:6ω3 was due mainly to those in PL.
