The lipid concentrations were high in the ovaries, decreased to low levels at nauplius and zoea1 stages, and then remained roughly constant during the subsequent stages to post-larva1. The marked decrease in lipid concentrations during the period of ovaries to early zoeal stages was mainly due to those in both phospholipids (PL) and triglycerides (TG) which were the major lipid classes throughout the larval developmental stages. The free sterol concentrations did not vary notably during the larval development from nauplius to post-larva1. As for total lipids, the proportions of highly unsaturated fatty acids such as 20:5ω3, 22:6ω3, and 20:4ω6 increased during the period of ovaries to zoea1 stage, whereas those of saturated and monoene fatty acids, specifically 16:0 and 16:1, decreased during the same period. Moreover, the decrease in the proportions of 16:1 and 18:1 during the above period was attributable mainly to those in both TG and PL, but the increase in the proportion of 20:5ω3 and 22:6ω3 was due mainly to those in PL.}, pages = {205--212}, title = {Variation in Lipid Compositions during the Larval Development of the Prawn (Penaeus japonicus)}, volume = {31}, year = {} }
