摘要
本文对大亚湾73种鱼体重和体长之间的相关关系进行比较研究。结果表明,鱼类的体重和体长呈显著的正相关;相关式指数b与鱼类生长特点之间存在着密切的联系。文中对这些关系进行了探讨。
The Weight-length relationship was compared in 73 species of fishes from Daya Bay. The results showed that the Weight was strongly and positively correlated with the length in each of the 73 species, the exponentials of the regression equations b ranged from 1.947 to 3.790 and the constants a from 4.746X10(-7) to 2.221X10(-3). There were 29.8% isometric growth and 72.2% allometric growth in 73 species. The exponentials b were significantly related to the growth of fishes. The relationship between b and the rate of the coefficient of condition of the maximal individual and minimal individual was given by the regression equation:These relations were discussed.
