为了研究鲎形体与体重之间的异速生长关系,进一步探讨其生长特性,分别测定分析圆尾鲎(Carcinoscorpius rotundicauda)和中国鲎(Tachypleus tridentatus)不同年龄段、不同龄期及不同性别的形态参数(头胸甲宽度及体重)。结果表明,圆尾鲎与中国鲎各年龄段、各龄期及不同龄期的雌、雄鲎头胸甲宽度与体重均为极显著正相关,决定系数R2﹥0.81。异速生长曲线斜率-回归系数b(体重的log值与前体宽度的log值)均大于1,总体表现为随着龄期的增长而不断增加,且雌鲎体重相对于头胸甲宽度的增长率大于雄鲎。
In order to study the allometric relationship between body size and body weight, the growth characteristics were further investigated. The morphological parameters of Carcinoscorpius rotundicauda and Tachypleus tridentatus at different ages, different ages and different genders (Head and breastplate width and weight). The results showed that there was a significant and significant positive correlation between the width and body weight of the trichomes and the weight of the females and males of all ages, ages and different ages in China. The coefficient of determination R2> 0.81. The slope - regression coefficient b (log of body weight and the log of body width) of allometric growth curves were all greater than 1, showing an overall increase with age, and the female body weight relative to the head and chest width The growth rate is greater than that of males.
