摘要
分别采用水丝蚓(Limnodrilus sp.)、卤虫无节幼体(Artemia nauplii)、枝角类(Moina sp.)和人工饲料饲养西伯利亚鲟仔鱼30d,研究不同开口饵料对西伯利亚鲟仔鱼生长、存活率和体成分的影响.结果表明:卤虫无节幼体为西伯利亚鲟最适开口饵料,仔鱼的存活率最高(96.67%);投喂水丝蚓组生长速度最快;而人工饲料组生长速度明显低于其他组,且成活率最低.不同开口饵料组间仔鱼体成分差异显著,人工饲料组水分含量最高,且粗蛋白和粗灰分含量最低.采用卤虫无节幼体为西伯利亚鲟仔鱼开口饵料,然后采用水丝蚓进行强化培育,能获得较好的生长速度和存活率.
Siberian sturgeon （Acipenser baerii ） larvae were raised with Limnodrilus sp. , Artemia nauplii, Moina sp. , and artificial commercial diet for 30 days to investigate the effects of different initial feeding diets on the growth, survival, and body biochemical composition of the larvae. The results showed that A. nauplii was the best initial feeding diet, with the survival rate of A. baerii larvae being significant higher （96.67%） than the others. Feeding with Limnodrilus sp. gave the highest growth rate of A. baerii larvae, while feeding with artificial commercial diet gave the lowest efficiency on the growth rate and survival rate of the larvae. The larvae raised with different diets had significantly different body biochemical composition. After fed with artificial commercial diet, the larvae had the highest moisture content but the lowest crude protein and crude ash contents. Taking A. nauplii as the initial feeding diet and then feeding with Limnodrilas sp. could gave the ideal growth and survival rates of A. baerii larvae.
