饲养系统被定义为所有喂养标准和做法，用于向动物提供营养充足的饲料，以维持正常的生长、健康和繁殖。鱼的饲养仍然是一种“艺术形式”，由养殖者而不是鱼来决定饲料的摄取量，尽管目前普遍使用的饲料已大大改善，营养丰富。本文回顾了设计有效饲养系统的核心因素，解决了一般使用系统的一些局限性，概述了预测生长的现代方法，并从生物遗传学的角度评估了能量和蛋白质需求。日粮能量和蛋白质需要量是根据能量摄入量、日粮蛋白质与能量比和氮潴留来确定的，并应用这些原则来确定一套饲养标准。
Feeding systems are defined as all feeding standards and practices used to deliver nutritionally adequate diets to animals in such a way as to maintain normal growth, health, and reproduction. Fish feeding continues to be an "art-form", with farmers, not the fish, determining feed intake even though greatly improved, nutrient-dense feeds are in general use. The paper reviews factors central to the design of effective feeding systems, addresses some limitations of systems in general use, outlines modern methods of predicting growth, and assesses energy and protein requirements in terms of biogenetics. Dietary energy and protein requirements are developed from energy intake, the protein: energy ratios of diets and nitrogen retention, and these principles are applied to define a set of feeding standards.
