Feed cost represents a significant proportion of production cost for most fish culture operations and proteins represent about 50% of feed cost. In order to improve profitability, fish feed manufacturers are progressively reducing fish meal levels in their feeds and are relying increasingly on more economical protein sources. The essential amino acids (EAAs) composition of many economical protein sources is generally less good than that of fish meal. Consequently, more attention needs to be paid to ensuring that EAA requirements of the fish are met.

对于大多数鱼类养殖作业来说，饲料成本占生产成本的很大一部分，而蛋白质约占饲料成本的 50%。为了提高盈利能力，鱼饲料制造商正在逐步降低饲料中的鱼粉含量，并越来越依赖更经济的蛋白质来源。许多经济蛋白质来源的必需氨基酸（EAAs）组成通常不如鱼粉。因此，需要更加注意确保满足鱼类的 EAA 要求。
