不同饵料形态对暗纹东方鲀幼鱼生长的影响

Effects of different feed forms on the growth of juvenile Takifugu obscurus

为探索提升暗纹东方鲀(Takifugu obscurus)幼鱼养殖技术,开展了饲料形态对暗纹东方鲀幼鱼生长影响的相关研究。将同一种粉状配合饲料,制成团状和软颗粒2种形态,对比研究其对暗纹东方鲀幼鱼(0.680±0.007)g生长的影响。经过30 d的养殖,结果表明,团状饲料组的相对增重率、特定生长率分别达到了(309.47±3.00)%和(2.04±0.01)%·d^(-1),饲料效率为(80.92±2.06)%,存活率为(64.29±2.02)%,显著高于软颗粒沉性饲料组(P<0.05),团状饲料组的水质较稳定,说明团状饲料为暗纹东方鲀幼鱼更适宜的饲料形态。研究结果可为开发高品质暗纹东方鲀幼鱼饲料提供参考。

In this paper,the breeding technology of juvenile Takifugu obscurus was explored through study of different feed forms.The same kind of powdered artificial feeds were made into mass-particle and soft-particle,and the effect of different feed forms on the growth of juvenile T.obscurus with average body weight of(0.68±0.007) g was compared.After 30 days of breeding,the results showed that the relative weight gain rate and specific growth rate of the mass-particle group reached(309.47±3.00)% and(2.04±0.01)%·d~(-1),the feed efficiency was(80.92±2.06)%,and the survival rate was(64.29±2.02)%,which was significantly higher than that of soft-particle group(P<0.05),and the water quality was relatively stable.The results indicated that the mass-particle feed was more suitable for juvenile T.obscurus.The research results provide a reference for developing high-quality feed for juvenile T.obscurus.
