This research was conducted to gather some basic information necessary for the development of non-fish meal dry diets for yellowtail. For the improvement of dietary value of non-fish meal diets supplementation of essential amino acids (EAA) is necessary, taking into consideration that their absorption into plasma must be synchronized with those derived from dietary protein for their effective utilization. Therefore, postprandial changes of FAA in plasma and feed digesta were examined in yellowtail by feeding them three types of diets {(soft-dry pellet (SDP), extruded pellet (EP), and single moist pellet (SMP)}, all having almost the same formulation with or without supplemental EAA.The supplemental EAA were found to be efficiently absorbed by yellowtail improving feed performances differing between diets, being highest for the SDP and lowest for the SMP group. However, the growth performance of fish fed the non-fish meal diets with EAA were inferior to those of fish on the control fish meal diet, in spite of the fact that the former were fortified with EAA to simulate the levels of the control diet. Although supplemental EAA were efficiently absorbed, the plasma methionine levels were markedly higher than those of fish fed the control diet. This may have caused an amino acid imbalance may have lowering the feed performances. For effective utilization, absorption of supplemental crystalline EAA into plasma must be synchronized with those derived from dietary protein, and this was found to be closely related to evacuation timing of the diet from the stomach. Thus the utilization efficiency differed between types of diets based on their physical properties such as hardness.

本研究的目的是收集开发黄尾鱼非鱼粉干饲料所需的一些基本信息。为了提高非鱼粉饮食的膳食价值，补充必需氨基酸（EAA）是必要的，考虑到它们在血浆中的吸收必须与来自膳食蛋白质的氨基酸同步才能有效利用。因此，通过饲喂三种类型的日粮{（软干颗粒（SDP）、挤压颗粒（EP）和单一湿颗粒（SMP）}）来检查黄尾鱼血浆和饲料消化液中FAA的餐后变化，所有饲料都具有几乎相同的配方，添加或不添加补充EAA。发现补充EAA可以被黄尾鱼有效吸收，改善不同饲料性能的黄尾鱼。 饮食，SDP 组最高，SMP 组最低。然而，饲喂含有 EAA 的非鱼粉饲料的鱼的生长性能不如饲喂对照鱼粉饲料的鱼，尽管前者添加了 EAA 以模拟对照饲料的水平。尽管补充的 EAA 被有效吸收，但血浆蛋氨酸水平明显高于喂食对照饲料的鱼。这可能导致了氨基 酸失衡可能会降低饲料性能。为了有效利用，血浆中补充的结晶 EAA 的吸收必须与膳食蛋白质中的吸收同步，并且发现这与饮食从胃中的排出时间密切相关。因此，不同类型日粮的利用效率因其物理特性（如硬度）而有所不同。
