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.
