海水仔稚鱼营养研究,特别是在n-3高度不饱和脂肪酸和卵磷脂等方面,国外已取得显著进展。迄今,我国鱼类营养研究基本集中于幼鱼和成鱼阶段,仔稚鱼阶段所见报道甚少。目前,我国养殖的名贵海鱼,其生产性育苗因在仔稚鱼阶段易出现大量死亡,成活率一般低于20％,因而尽快提高海鱼生产性育苗的成活率已成为急需解决的关键问题。 Sea larvae juvenile fish nutrition research, especially in n-3 highly unsaturated fatty acids and lecithin, etc., have made remarkable progress abroad. So far, the research on fish nutrition in our country basically focuses on the juvenile and adult stages, and little is known about the larval stage. At present, due to the large number of deaths in the breeding larvae of the expensive marine fish breeding in our country, the survival rate is generally below 20%. Therefore, raising the survival rate of the breeding fish as soon as possible has become a key issue urgently needed to be solved.
