| 摘 要： | 试验设置了5个养殖密度,分别为1 000、2 000、3 000、4 000、5 000尾/缸,经过70 d的养殖和观察,发现养殖密度对哲罗鱼稚鱼的存活率、肥满度、特定生长率和变异系数的影响并不显著.各密度组的存活率分别为87.7%、94.25%、92.95%、91.45%和91.12%,肥满度为0.728～0.793,特定生长率平均值为3.11%,体质量变异系数为0.49%～18.73%.研究结果表明,哲罗鱼稚鱼完全可以在较高的养殖密度下进行培育.

| Abstract: | An experiment was conducted to study the effects of stocking density on the growth and survival of juvenile Hucho taimen(Pallas).Experimental fish were reared at five different stocking densities,1000,2000,3000,4000 and 5000 individuals per tank.Result showed that stocking density had insignificant effects on the survival rate,relative fatness,special growth rate and variation coefficient of body weight for juvenile H.taimen.The survival rates of the groups with 1000,2000,3000,4000 and 5000 individuals per ... |
