蝲蛄的外形及呼吸系统观察

THE OBSERVATION OF THREE CARYFISH SPECIES' MORPHOLOGY AND RESPIRATORY SYSTEM

详细描述东北拟蝲蛄的一般外部形态(其它虾类也未报道过的形态部分)及呼吸系统,与朝鲜蝲蛄、克氏原蝲蛄作具体比较,克氏原蝲蛄与东北拟蝲蛄差异较大,地理分布较远,而朝鲜蝲蛄与东北拟蝲蛄相近,有些特征介于二者之间.

The distribution of Cambaroides dauricus, Cambaroides smilis and Procambarus clarkii in China is reported in the present paper. Further the morphological character and respiratory system of Cambaroides dauricus is described in detail and at the same time its comparison with relative part of Procambarus clarkii and Cambaroides similis is made;The present result supports the hypothesis that Cambatoides dauricus has a tighter relationship with Cambaroides similis, but less tight than Procambarus clarkii. Fourteen diagrams and three key crayfish specids are enclosed in the present paper.
