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 Limnodrilus sp. could gave the ideal growth and survival rates of A. baerii larvae.
将西伯利亚鲟(Acipenser baerii)幼鱼与颤蚓属、卤虫无节幼体、裸腹溞属以及商业人工饲料一起饲养30天,以研究不同初始投喂饲料对幼鱼生长、存活及鱼体生化组成的影响。结果表明,卤虫无节幼体是最佳初始投喂饲料,西伯利亚鲟幼鱼的存活率显著高于其他组(96.67%)。投喂颤蚓属使西伯利亚鲟幼鱼生长速率最高,而投喂商业人工饲料时幼鱼的生长速率和存活率最低。用不同饲料饲养的幼鱼其鱼体生化组成有显著差异。投喂商业人工饲料后,幼鱼水分含量最高,但粗蛋白和粗灰分含量最低。以卤虫无节幼体作为初始投喂饲料,然后投喂颤蚓属,可使西伯利亚鲟幼鱼获得理想的生长和存活率。
