项目摘要

This research was conducted to gather some basic information necessary for the development of environment friendly aquafeed using with plant protein sources. The availability and safety of the soybean meal and corn gluten meal from gene modified organisms and the many variety of fish meal were determined using with aquaculture species, yellowtail, red sea bream, rainbow trout and carp in order to develop the low pollutant excretion feed without high density formulation of good quality animal protein sources, such as fish meal.A series of feeding experiments were conducted to develop eco-diets, namely, determination of the absorption of phosphorus from feed ingredients, and development of the low discharge feed in combination of plant protein sources and fish meal. Also the availability and safety of soybean meal and corn gluten meal made of gene modified organisms were determined, and efficient component of silk worm pupae meal also examined. Promotion of protein sparing effect by dietary lipid in yellowtail was tested to reduce the excretion of nitrogen and phosphorus.Formula of plant ingredients which contain lower phosphorus, such as soybean meal and corn gluten meal could produce the diet which reduce the excretion of phosphorus without of reduction of growth of fish. And inclusion of high amount of dietary lipid made success in decent of nitrogen excretion by protein sparing effect. The availability of soybean meal and corn gluten meal derived from gene-modified organisms was not different from that of authentic non-gene modified plants.

本研究旨在为利用植物蛋白源开发环境友好型水产饲料提供必要的基础资料。为了开发低污染排泄饲料，在不使用鱼粉等优质动物蛋白源的高密度配方的情况下，以养殖品种黄尾鱼、红鲷鱼、虹鳟鱼和鲤鱼为原料，对转基因豆粕、玉米蛋白粉和多种鱼粉的可获得性和安全性进行了研究。为开发生态饲料，进行了一系列饲养试验，即测定饲料原料中磷的吸收量，开发植物蛋白源与鱼粉相结合的低排放饲料。测定了转基因豆粕和玉米蛋白粉的可用性和安全性，并对蚕蛹粉的有效成分进行了检测。研究了饲料脂肪对黄尾鱼蛋白质节约的促进作用，以减少黄尾鱼氮、磷的排泄。采用豆粕、玉米蛋白粉等含磷较低的植物性原料配方，可以在不影响鱼体生长的前提下，减少磷的排泄量。在饲料中加入大量脂肪，通过节约蛋白质的作用，成功地改善了氮的排泄。来自转基因生物的豆粕和玉米蛋白粉的可得性与正宗的非转基因植物没有区别。
