文章采集珠江水系西江和东江野生草鱼共60尾对其形态特征和生长特性进行分析。两个江草鱼可数性状基本相同,传统测量数据和框架测量数据的差异分析均表明西江和东江野生草鱼的形态差异不显著,属于同一群体。并拟合西江和东江1龄草鱼体长与鳞径关系的方程和体重与体长关系的方程,并计算了西江和东江草鱼肥满度。
In this paper, 60 species of wild grass carp from Xijiang River and Dongjiang River in the Pearl River were collected to analyze their morphological characteristics and growth characteristics. The countable traits of the two grass carps are basically the same, and the difference analysis of the traditional measurement data and the frame measurement data shows that the morphological differences of the wild grass carp in the Xijiang River and the Dongjiang River are not significant and belong to the same group. The equation of relationship between the body length and the diameter of the first-grade grass carp and the relationship between body weight and body length of the grass carp in the Xijiang River and the Dongjiang River were fitted, and the fatness of grass carp in the Xijiang River and Dongjiang River was calculated.
