| 摘 要： | 目的]加深对大鳞黑线餐鱼的认识,进一步掌握其生态习性,获得其生物学特征。方法]参照内陆水域渔业自然资源调查手册对2011年9月在陕西汉江干流石泉段采集到的1尾黑线餐鱼属鱼类标本进行测量和研究,并与1979年捕获的标本进行比对。结果]该次捕获的标本除体长和全长外,其他各对比项目与正模标本的差异很小;大鳞黑线餐鱼除了可分布在水域上游山间溪流中,也可生活于大水面缓流区;大鳞黑线餐鱼在汉江水系仍有分布,但资源量极小。结论]结果为该濒危鱼类的保护提供了依据。

| Abstract: | Objective] The aim was to deepen the understanding to Atrilinea roulei macrolepis,further grasp its ecological habit and obtain its biological characteristics.Methods] Consulting fisheries natural resources investigation handbook in inner waters,a Atrilinea roulei macrolepis specimen collected in the Shiquan of Hanjiang trunk stream in Shaanxi in September of 2011 were measured and studied,and it was compared with the specimen collected in 1979.Result] Excepting the body length and overall length of the specimen,other compared items have little differences with holotype;Atrilinea roulei macrolepis can not only distributed in the mountain stream of upper waters,but also can live in the area of slack water of large water surface,moreover,there is a small quantity of it in Hanjiang River system.Conclusion] The results provide references for the protection of endangered fishes. |
