采用丰年虫、冰冻轮虫、水蚯蚓、人工配合饲料4种开口饵料投喂四川裂腹鱼( Schizothorax kozlovi Nikol-sky)仔鱼30 d,研究其对四川裂腹鱼仔鱼生长和成活率的影响。结果显示:投喂水蚯蚓和丰年虫能保证四川裂腹鱼仔鱼具有较快的生长速度和较高的成活率。而人工配合饲料组生长速度明显低于其他组,且成活率最低。结果表明,4种开口饵料中,丰年虫是四川裂腹鱼仔鱼最适宜的开口饵料。
採用豐年蟲、冰凍輪蟲、水蚯蚓、人工配閤飼料4種開口餌料投餵四川裂腹魚( Schizothorax kozlovi Nikol-sky)仔魚30 d,研究其對四川裂腹魚仔魚生長和成活率的影響。結果顯示:投餵水蚯蚓和豐年蟲能保證四川裂腹魚仔魚具有較快的生長速度和較高的成活率。而人工配閤飼料組生長速度明顯低于其他組,且成活率最低。結果錶明,4種開口餌料中,豐年蟲是四川裂腹魚仔魚最適宜的開口餌料。

Schizothorax kozlovi Nikolsky larvae were raised with Tubifex sp.fairy shrimp, frozened rotifer and artificial commercial diet for 30 days to study the effects of the four different feeding diets on the growth and survival of the larvae . The results showed that the larvae fed with Tubifex sp.and fairy shrimp had significant higher survival rates than those fed with the artificial commercial group .The larvae fed with Tubifexsp.had the highest growth rate , while those fed with arti-ficial commercial diet had the lowest efficiency on the growth rate and survival rate .The results indicated that fairy shrimp was the best initial feeding diet for S.kozlovi Nikolsky larvae .
