| 摘 要： | 采用灯光诱鱼协同缓沉饲料驯食过渡至浮性颗粒饲料投喂的方法,高密度驯养长江刀鲚(Coilia nasus)鱼种,建立了8~10 cm刀鲚鱼种转食浮性颗粒饲料的人工饲养技术,为刀鲚的集约化养殖提供技术支撑。结果显示,经16 d的驯食,刀鲚在投饵后1 h之内吃完饲料,驯食期间刀鲚平均成活率为75.05%。闪光诱鱼比常光诱鱼更利于刀鲚鱼种驯食浮性颗粒饲料;先期对浮性颗粒饲料处理成缓沉投饲驯食并逐步过渡至完全摄食浮性颗粒饲料的操作能让刀鲚鱼种在短期内(16 d)完全摄食浮性颗粒饲料。

| Abstract: | Using light luring fish, collaborating buoyancy granule feedstuff feeding Coilia nasus of high density, the exper-iment were to establish the artificial breeding technology of C.nasus, and provide technical reference for the industrializa -tion of the fish breeding.The results showed that the feed could be eaten within one hour after 16 days of domestication, and the average survival rate was 75.05 percent.Flash lure fish was more conducive than regular light lure , which could make the fish adapt to the buoyancy pellet feed in a short period of time . |
