高度不饱和脂肪酸(HUFA)对海水仔鱼营养的影响

The Requirements of some Marine Fish Larvae for Highly Unsaturated Fatty Acids

综述了海水仔鱼对ＨＵＦＡ的营养需要。亲鱼的ＨＵＦＡ的营养状况直接影响海水仔鱼的存活率，海水仔鱼对 ＨＵＦＡ的需要量因种而异，一般为其饵料干重的１．２％～６％。海水仔鱼不但对ＨＵＦＡ的总量有一定的需要，而且对ＤＨＡ、ＥＰＡ和ＡＡ的比例及各自的需要量也有一定的要求。

The study is conducted to probe the requirements of some marine fish larvae (HUFA) for highly unsaturated fatty acids in this paper. The condition of broodstock nutrition has significant effects upon the eggs quality and the death rate of larvae. The HUFA requirement of one fish larvae is different from each other, usually 1. 2%～6% of its dry food. Not only the contents of HUFA but also the DHA: EPA: AA ratio and their individual content in absolute terms are important for fish larvae nutrition.
