Study on Growth Characteristics of One-Year-Old Overwintering Takifugu flavidus under Artificial Culturing Condition

In this paper,the trials of the growth characteristics of Takifugu flavidus under artificial culturing condition were conducted.By experimental data processing and analysis,the results showed that the T.flavidus reached average total body length of 20.84±1.07 cm,average body weight of 242.11±28.23 g after 197 days rearing from average total length of 14.07±1.31 cm,average body weight of 77.49±26.50 g.The total length increased by 0.03 cm on average,the growth ratio was 48.12%,and the body weight was gained at the rate of 0.71 g per day on average and the growth ratio was 212.44%.The linear relationship of total length and body weight was W=0.033 7 L2.912 2(R2=0.936 7).The power was near 3,which indicated the growth of weight was the same as that of total length.The linear relationship of total length and culture time was L= 0.035 T+14.191(R2=0.977 3),and the linear relationship of body weight and culture time was W= 82.616 e 0.005 7 T(R2=0.985 8).
