Abstract: The posture characteristics and systematic measurement of Burbot was compared be tween Jingbo Lake and Baikal. The genetic variation of the posture characteristics of the Jingbo Lake Burbot was discussed from t-test analyses.Mayr Formula and C.D≥1.28 as systematic index to check Jingbo Lake Burbot. According to observations its systematic position is Lota lota lota(Linné).

Key words: Lota lota(Linneaus), variation of the posture characteristics, different coe fficient, subspecies, Jingbo Lake

摘要: 通过对位处黑龙江水系南缘位置的镜泊湖所产江鳕 体态性状的系统测量统计数值,与属北极海水系的贝加尔湖江鳕的同等性状进行对比,用统计学t检验方法查看了镜泊湖江鳕的性状变异状况;又用Mayr差异系数公式和C.D≥1.28的亚种划分指标,逐项查验,并对两个达标性状进行了具体分析和评价,最后得出镜泊湖江鳕仍属江鳕指名亚种的结论。
