摘要: 采用丰年虫、水蚯蚓、微囊饲料3种饵料的不同配合策略,对圆口铜鱼(Coreius guichenoti)仔稚鱼投喂60 d,以研究对其存活率和生长率的影响。结果表明,30日龄后投喂水蚯蚓的存活率、全长、体长、体重均高于其他试验组,特定生长率为(4.44±0.30)%/d,显著高于对照组和W15微囊饲料组。15日龄后转投微囊饲料组的全长、体长、体重和特定生长率最低。不同的转食策略对圆口铜鱼仔稚鱼的存活及生长有显著的影响,30日龄后投喂水蚯蚓能有效地提高存活率及生长率。

Abstract: The Coreius guichenoti larvae were raised with fairy shrimp, limnodrilus and particulate feed bait feed for 60 days to study the effects of the three different feeding method on the survival rate and growth rate. It was found that the larvae fed with limnodrilus had higher survival rate, total length, body length, weight than other groups after 30 days post hatching(dph), and the specific growth rate was(4.44±0.30)%/d. The total length, body length, weight and specific growth rate were the lowest of the particulate feed group after 15dph. The results indicated that different feeding method have a significant effect on the survival and growth of the larvae. Feeding the fairy shrimp before 30 dph, feeding the limnodrilus after 30 dph can effectively improve the survival rate and growth rate.

Key words: Coreius guichenoti, larvae, feeding method, survival rate, growth rate
