摘要

鱼苗营养是可持续水产养殖生产的最基本要素。它对商业水产养殖的繁殖性能和盈利能力的影响一直是大量研究的主题。本文回顾了相关文献,研究了尼罗罗非鱼育苗营养对成熟度、繁殖力、受精率、胚胎发育、幼体质量和存活率等参数的影响。讨论了按不同比例提供由必需的宏量和微量营养素(包括蛋白质、脂类、碳水化合物、维生素、矿物质和功能性添加剂,如益生元、酶、激素和益生菌)组成的营养日粮。特别强调了有关日粮蛋白质和脂质对卵黄发生和卵巢成熟、繁殖力、卵孵化率、幼虫质量和鱼苗成活率的影响的文献。此外,还介绍了饲养方式对繁殖性能的影响。

Broodstock nutrition in Nile tilapia and its implications on reproductive efficiency
Broodstock nutrition is the most essential constituent of sustainable aquaculture production. Its impact on the reproductive performance and profitability of commercial aquaculture has been the subject of considerable research. The present paper reviews the literature available on the subject, examining the implication of Nile tilapia broodstock nutrition on parameters including maturation, fecundity, fertilization, embryo development, larval quality, and survival rate. The provision of a nutritive diet composed of essential macro- and micronutrients including proteins, lipids, carbohydrates, vitamins, minerals, and functional additives, such as prebiotics, enzymes, hormones, and probiotics, in different proportions is discussed. Special emphasis is given to literature dealing with the effects of dietary protein and lipid on vitellogenesis and ovarian maturation, fecundity, egg hatching rate, larval quality, and fry survival number. The impact of the feeding regime on reproductive performance is described.
