亲鱼脂类营养对鱼类生殖性能的影响

Effect of Lipid Nutrition on Reproductive Performance of Broodstock Fish

亲鱼饲料的营养质量是影响生殖性能的主要因素之一,目前的研究大多集中在脂类营养方面。本文主要综述了饲料脂类成分对亲鱼的产卵量、卵和仔鱼质量、胚胎发育、精卵的脂肪酸构成的影响,以及营养成分影响生殖性能的机制。

In many cultured fish species, particularly marine fishes, unpredictable and variable reproductive performance is an important limiting factor for the successful mass seed prnduction. Lipid and fatty acid composition of broodstock diet have been identified as major dietary factors that determine successful reproduction and survival of offspring, and most of the reports available on broodstock nutrition are about lipid nutrition. Thus this paper mainly reviewed the effects of dietary lipid and fatty acids on fecundity, egg and larval quality, embryo development,and fatty acid composition in eggs and sperm; the possible mechanisms of nutrition ingredients affecting reproductive performance.
