①试验证明草鱼苗摄食轮虫较多,但捕食搔很少,在环境没有其他饵料存在时,也可能摄取小部分搔。嫉鱼苗摄取浮游动物如搔、大剑搔、轮虫无明显的选择性。②利用放射性同位素标记饵料,可以研究一尾家鱼鱼苗的摄食量。③鱼苗摄食带标记饲料最高,而草鱼苗摄食带标记的臂尾轮虫也较显著。④本实验使用的标记饵料培养液,其故射性比度100微居里/立升为合适。
① The test proved that grass fishes eat more rotifers, but there are few prey scratches. When there is no other food in the environment, it may also take a small part of scratches. Fish fry intake of zooplankton such as scratching, sword scratching, rotifer no obvious selectivity. ② the use of radioactive isotope labeled food, you can study the food intake of a home fish fry. ③ The highest feed intake of fish fry, and the feeding of grass carp fry with Brachionus rotundus also more significant. ④ The experiment used in the labeling of bait culture medium, its projectile specific gravity than 100 micro-Curr / liter as appropriate.
