尖嘴臀鳞鱼生态习性及分布初探
摘要
由于食肉性鱼类在塔里木盆地的引进
使尖嘴臀鳞鱼幼体存活甚少
加之人类过度捕捞
近十年内尖嘴臀鳞鱼的原分布范围急剧缩小
分布数量锐减
目前仅少量分布于开都河及塔里木河上游人烟稀少地区水域。在大尤尔都斯盆地
尖嘴臀鳞鱼仅活动于水深大于1.5m的流动水体
5月15日至30日行短距离迥游至繁殖区
迥游距离约15km左右
繁殖区水质pH值在6.0以上
水深多大于2m。
Abstract
Thete are a few of Schizothorax biddulphi Gflnther larva to live because of carnivorous fish's intno duced in Talimu Basin. Another reason is excessive harvest
the Schizothorax. biddulphi Guunther distribu tive range had droped sharply and so did it's distributive amount during
the past ten years. At present
only a few distribute on a sparse population's waters in the upper reacher of Talimu River and Kaidu River. In Dayouerdusi Basin
the Schizotharax biddulphi Gunther live in depth about 1. 5 meters in flow ng water area. From May 15 to May 30
they migrate for a distance about 15 kilometres to breeding distrer where pH valus is more than 6. 0 and the depth of water is more than 2 metres.
