Dietary lipid manipulation in the feed of commercially cultured finfish is used not only to improve production and culture but also to enhance their reproductive performances. The inclusion of lipid in broodstock diet positively affects growth, immunological responses, gonadogenesis, and larval survival. In this review, existing literature on the importance of freshwater finfish species to aquaculture and the inclusion of dietary lipid compounds in freshwater fish feed to accelerate the reproduction rate is being summarized and discussed. Although lipid compounds have been confirmed to improve reproductive performance, only a few members of the most economically important species have reaped benefits from quantitative and qualitative lipid studies. There is a knowledge gap on the effective inclusion and utilization of dietary lipids on gonad maturation, fecundity, fertilization, egg morphology, hatching rate, and consequently, larval quality contributing to the survival and good performance of freshwater fish culture. This review provides a baseline for potential future research for optimizing dietary lipid inclusion in freshwater broodstock diets.
在商业养殖的食用鱼饲料中进行膳食脂质调控，不仅用于提高产量和养殖效果，还用于增强其繁殖性能。在亲鱼饲料中添加脂质对生长、免疫反应、性腺发育和幼体存活有积极影响。在这篇综述中，总结并讨论了关于淡水食用鱼品种对水产养殖的重要性以及在淡水鱼饲料中添加膳食脂质化合物以提高繁殖率的现有文献。尽管脂质化合物已被证实可改善繁殖性能，但在最具经济重要性的鱼类品种中，只有少数品种从定量和定性的脂质研究中受益。在膳食脂质对性腺成熟、繁殖力、受精、卵形态、孵化率以及因此对淡水鱼养殖的幼体质量（影响幼体存活和良好性能）的有效添加和利用方面，存在知识空白。这篇综述为未来优化淡水亲鱼饲料中膳食脂质添加量的潜在研究提供了一个基线。
