摘　　要：对2008年10月到2009年2月采于嘉陵江南充段的117尾兴凯鱊进行形态测量,单因素方差分析显示:兴凯鱊比例性状在雌雄鱼之间无显著差异;体长质量关系和肥满度分析表明,体长大于8 cm时,雌鱼体质量增长快于雄鱼;相同体长组中,雌鱼肥满度指数稍大于雄鱼.Form October 2008 to February 2009, 117 specimens of Acheilognathus chankaensis were measured which were collected from Jialing River, a branch showed that there were no differences between male of Yangtze River. One-way analysis of variance （ANOVA） and female in body length/body height, body length/head length, head length/snout, length. Length-Weight Relationship and Fullness index indicated that when the body length grew up to 8 cm, the weight growth of females would be faster than that of males. In the same body-length group, the fullness index of females was higher than males.
