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