摘要
n-3高不饱和脂肪酸(HUFA)对鱼类亲体性腺发育、卵子和精子质量、产卵量、受精率、孵化率、仔鱼成活率和质量有重要影响。鱼类体内在一系列去饱和酶和延长酶作用下合成n-3HUFA,淡水鱼类和鲑鳟科鱼类一般从饲料中摄取亚麻酸用于合成n-3 HUFA,而海水鱼类需要从饲料中直接摄取n-3 HUFA。本文综述了鱼体内n-3 HUFA合成路径及其对亲鱼繁殖性能的影响,同时对n-3 HUFA天然来源和替代来源进行了阐述,以期为鱼类亲体的脂肪酸营养和机制方面研究提供一定的参考。
n-3 highly unsaturated fatty acids(HUFA)has multiple influences on the gonad development,gamete quality,fecundity,fertilization rate,hatching rate and survival rate of larva of fish.For fish,the synthesis of n-3 HUFA needs a series of reaction catalyzed by some enzyme like desaturation and Elovl.Generally,n-3 HUFA in freshwater fish and salmon trout can be synthesised by diet linolenic acid(LAN),but not for seawater fish,they directly intake HUFA from diet.In this review,the synthesis process of n-3 HUFA and its effects on reproductive performance of fish were summarized for providing some references for fatty acid nutrition of broodstock of fish and its mechanism.
