摘要
报道了美洲鳗( Anguilla rostrata )白仔对水蚯蚓( Tubifex sp )、卤虫( Artem ia sp )和鱼卵三种饵料的选择性、消化率及摄食后的生长情况。试验结果表明,美洲鳗白仔对上述3 种饵料的选择性明显不同:水蚯蚓> 卤虫> 鱼卵。从其对3 种饵料的消化率及生长情况来看,水蚯蚓和卤虫对美洲鳗白仔的饲养效果较好,而鱼卵的饲养效果则较差。
Food selection and digestibility of tubifex worms, brine shrimps and fish eggs by the American glass eel and its growth on the three diets were reported in this paper. The results showed that the American glass eel had a significant preferential selection over the three diets. Tubifex was its favorite starter food, followed by brine shrimp. Fish eggs were the least favorite. In terms of the digestibility and growth of the eels, the tubifexs and brine shrimps dietary effects were good and had no significant difference, while fish eggs were poor.
