クルマエビ幼生におけるコレステロールおよび大豆リン脂質の要求量

The present study is planned to examine the requirements of cholesterol for the prawn, Penaeusjaponicus, larvae in relation to the dietary levels of soybean phospholipids (PL). The experimentalgroups were designed as 2-way layout experiment (4x4 type): factor A, cholesterol content (%) indiets; factor B, soybean PL content (%) in diets. The zoea1 larvae of P.japonicus were reared with 16defined diets containing carrageenan as a binder for 7 days. The effects of cholesterol in improvinggrowth and survival of P.japonicus larvae seemed not to be affected by the dietary levels of soybeanPL. The optimum levels of cholesterol and soybean PL for P.japonicus larvae were estimated to be1.0% and 3.0%, respectively, when pollack liver oil was used as basal lipid sources.
