| 摘 要： | 文中根据1997～1999年和2001～2002年期间在南海北部底拖网调查的43种共33 389尾鱼的体长（叉长、肛长）和体重数据,应用统计分析方法对各鱼种体长与体重关系进行分析.结果表明,43种鱼分别隶属于4目16科25属,相关系数R^2的范围为0.764～0.993,相关系数R^2值相对较高,其中58%的R^2值超过0.95.幂指数b值范围为2.50～3.44,平均2.90.盒须图分析表明,50%的b值在2.79～3.01范围.经初步分析,43种主要经济鱼类中,有16种为等速生长、22种负的异速生长和5种正的异速生长.

| Abstract: | Based on length-weight data of 43 species of fish collected by trawl in northern South China Sea during 1997 to 2002 and 2001 to 2002, about 33 389 fishes were measured and weighted separately. The length-weight relationships of each species was statistically analyzed. The results indicate that the 43 species of fish belonging to 25 genera 16 families and 4 orders. All correlation coefficient R were high ranging from 0. 764 to 0.993, where 58% of 43 species showed R2 values greater than 0.95. The b values in the length-weight relationship varied from 2.50 to 3.44 with a mean of 2.90, The 50% of the b values ranged from 2.97 to 3.01 by Box-Whiskers plots. The growth pattern was determined by t-test which showed that 16 species where in isometric growth, 22 negative allometric and five,positive allometric growth. |
