1引言与目标满足养殖鱼类的日粮蛋白质需要量并充分了解相应的特定必需氨基酸(EAA)的需要量已变得十分迫切。考虑到鱼粉(FM)的可用性与成本的限制,我们需要使用一种或多种必需氨基酸的植物蛋白(PP)来源。近10年来,我们在寻找水产饲料中合适的鱼粉蛋白替代来源上取得了长足的进步。早前的研究证明了在补充限制性氨基酸而使日粮氨基酸组分平衡的条件下,金头鲷日粮中很高比例的鱼粉可使用
1 INTRODUCTION AND OBJECTIVES It has become increasingly urgent to meet the dietary protein requirements of farmed fish and to fully understand the needs of the corresponding essential amino acids (EAA). Given the availability and cost constraints of fishmeal (FM), we need plant protein (PP) sources that use one or more of the essential amino acids. In the last 10 years, we have made great strides in finding alternative sources of suitable fish protein in aquafeed. Earlier studies have demonstrated that a high proportion of fish meal in the Gilthead Finch can be used under the condition that dietary amino acid components are supplemented with limiting amino acids
