研究鱼的摄饵生态,弄清投饵量与生长量的关系是非常重要的。关于投饵量与生长量关系的研究进行得很多,在此,仅就虹鳟鱼各生长阶段的投饵计划作一介绍,介绍内容以我们的饲养实验结果为主。虹鳟不同体重、不同水温的最适投饵率,是采用表1所列的值。后在全国湖泊河流养殖研究会养鳟部会议上,对该表作了重 It is very important to study the feeding ecology of fish and find out the relationship between feeding amount and growth rate. There have been many studies on the relationship between the amount of feed and the amount of growth. Here, only the feeding plan of rainbow trout in each growth phase is introduced, and the introduction mainly focuses on the results of our feeding experiment. Rainbow trout of different weights, the optimum feeding rate of different water temperature is the value listed in Table 1. After the National Lakeshore Aquaculture Research Society raised trout meeting, made a heavy table
