池养菊黄东方鲀一龄越冬鱼种的生长特性

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

对菊黄鲀东方鲀一龄越冬鱼种在池塘养殖条件下的生长特性进行了研究。结果表明:平均全长14.07±1.31 cm,平均体重77.49±26.50 g的菊黄东方鲀经过197 d的培育后,全长增至20.84±1.07 cm,日均增长0.03 cm,全长增长率48.12%,体重增至242.11±28.23 g,日均增长0.71 g,体重增长率212.44%,体重与全长呈幂函数关系,关系式为:W=0.033 7L2.912(2R2=0.936 7),b值接近于3,属等速生长型。全长(L)与时间(T)表现为线性相关:L=0.035 T+14.191(R2=0.977 3),体重(W)与时间(T)表现为指数相关:W=82.616 e0.005 7 T(R2=0.985 8)。

In this paper, the trials of the growth characteristics of Takifuguflavidus 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 rear- ing 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 L29122（R2=0.936 7）. The power was near 3, which indicated the growth of weight was the same as that of to tal 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 00057T（R2=0.985 8）.
