摘要： 通过对在达里湖、岗更湖采取的鲫鱼进行形态特征、生物学特性测量分析研究,得出结论:达里湖鲫鱼属均匀生长型,其种群的繁殖能力也较强,但种群年龄结构不合理,应增加人工放流量和减少捕捞量。合理的捕捞规格为体长大于19.67cm,体重大于214.5g。

Abstract: Through measure,analysis and study on the morphological characteristics and the part biological characteristics,this paper showed that Carassius auratus grow style in Dali lake is homogeneous,the population reproductivity is better,but the population age structure is unreasonal,so the number of C}u-assius auratus卿 breed by man should be increased and the capture number in Dali Lake should be decreased.The reasonable capture size for Carassius auratus in Dali lake is that the body weight is more than 214.Sg,the body length is more than 19.67cm.

Key words: Dali lake, Carassius auratus (Linnaeus), Population, Morphology
