| 摘要: |
| 2002-2004年,在浙江衢州铜山源水库,对该库放养的美国大口胭脂鱼的生长情况进行了研究,结果表明,该水库美国大口胭脂鱼的鳞片以环片的切割型为主要年轮特征.用刺网所捕的美国大口胭脂鱼渔获物中以Ⅱ、Ⅲ、Ⅳ龄个体为主.体长和体重的关系式为:W=8.595×10-515 L2.662,Von Bertalanffy生长方程的主要生物学参数:L∞=36.54cm,W∞=1.245kg,k=0.6377,t0=-0.261龄,体重生长的拐点年龄tr=1.92龄,拐点体重Wr=0.396kg.与池养鱼类生长情况相比,铜山源水库的美国大口胭脂鱼生长较慢. |

| Abstract: |
| The growth performance of large mouth buffalo stocked in Tongshanyuan Reservoir in the pericKl of 2002-2004 was studied. The results showed large mouth buffalo, whose scales were mainly characterized by incision, was composed of groups aged Ⅱ、Ⅲ、Ⅳ in gill net catches. The relationship between the body-weight and the body-length can be described as W=8.595×10-515 L2.662. the growth patterns can be fitted to a Von Bertalanfiy Growth Model, in which L∞, W∞, k and t0 are 36.54cm, 1.245kg, 0.6377 and -0.261 ya respectively. At the broken point of the growth equation of body-weight, tr=1.92 ya and Wr=0.396kg. The growth of large mouth buffalo in Tongshanyuan Reservoir is slower than that of the fish fanned in ponds. |
