为了引起对虾的食欲,把大约含1.5%成份大体和短颈蛤(Tapes japonica)浸出液相同的晶体蛋白氨基酸混合物加到过去曾加以报导的精制饵料料~***中去,因为氨基酸混合物不纯,其中含有一些必需氨基酸,所以用这种试验饵料来测定对虾对氨基酸和蛋白质的需要是不合适的。因此必须对饵料成分加以改变,使用具有同样引诱效果的非必需物质来代替氨基酸混合物。 In order to elicit the appetite of the shrimp, approximately the same crystalline protein amino acid mixture, containing approximately 1.5% of the same extract as Tapes japonica, is added to the previously reported refined bait material ~ *** because the amino acid mixture is impure , Which contains some essential amino acids, so using this test bait to determine the needs of shrimp on amino acids and proteins is not appropriate. It is therefore necessary to change the composition of the bait to use non-essential substances with the same baiting effect instead of amino acid mixtures.
