对青狮潭水库太湖新银鱼的月龄生长进行全年连续采样分析 ,用 von Bertalanffy生长方程描述其生长特性 ,得到体长、体重关系式和生长方程 ,经 X2 检验显著服从 ( P<0 .0 5) ,并由此推导出体长和体重的生长速度方程及生长加速度方程。银鱼生长拐点在 4 .8月龄处。建议银鱼最适捕捞期为 1 1月
The monthly growth of Nelumbo nucifera in Qingshitan Reservoir was continuously sampled and analyzed by von Bertalanffy growth equation. The body length and body weight were calculated and the growth equation was obtained. The X2 test significantly obeys (P <0 .0 5), and then deduced the growth rate equation and growth acceleration equation of body length and body weight. Silverfish growth inflection point at 4.8 months of age. The optimal fishing season for silverfish is January 1
