利用人工繁殖孵化得到的杂交鳢、乌鳢、斑鳢仔鱼,在水温26±1℃下,进行三种仔鱼饥饿致死时间的试验。结果表明,三种仔鱼50%饥饿致死时间分别为14d、16-17d、10d;100%饥饿致死时间分别为19d、21d、15d。杂交鳢、乌鳢、斑鳢三种仔鱼对饥饿的耐受力强弱顺序依次为:乌鳢>杂交鳢>斑鳢。
The artificial hatching of hybrid 鳢, 鳢 鳢, 斑 鳢 larvae, the water temperature 26 ± 1 ℃, three kinds of larvae starvation lethal time of the experiment. The results showed that the lethal time of 50% hunger of three larvae was 14d, 16-17d and 10d, respectively. The lethal time of 100% starvation was 19d, 21d and 15d respectively. The order of tolerance to starvation of three larvae of hybrid 鳢, 鳢 鳢 and 斑 斑 were as follows: 鳢 鳢> hybrid 鳢> 斑 鳢.
