喀喇昆仑山-昆仑山地区渔业资源及渔业发展对策的初步研究

我国东帕米尔、喀喇昆仑山和昆仑山地区是一个人口稀少,人们难于了解的高山地区,面积约 40×10⁴km²。本文除报道有关该区水生生物、鱼类及渔业概况外,并通过作者1974年、1987年、1988年实地考察资料的对比来说明本区当地鱼类受到诸方不利因素的严重威胁而明显减少。最后对该区渔业发展提出渔业资源合理利用和保护管理的主要对策方案。

A PRELIMINARY STUDY OF THE FISHERY RESOURCES AND THE COUNTERMEASURES OF FISHERY DEVELOPMENT IN THE REGION OF THE KARAKORUM-KUNLUN MOUNTAINS, CHINA

The region of the Karakorum and Kunlun mountains is a high and sparsely populated region with an area of about 400 000 square kilometers. It is one of the less studied regions in China. The present paper deals with the results of surveys on hydrobios and fish as well as fishery in the water systems of this region during the years 1974 and 1987-1988. Altogether 41 collecting localities were set up there. 1516 fish specimens were collected from 36 collecting localities and 40 bottles of the hydrobios specimens from 16 ones.This paper comprises 5 parts: 1) the natural enviroment of the water system and the collecting localities; 2) the hydrobios of this region and their characteristics; 3) the compositions of fish fauna and the natural food of fish; 4) the fish resources and the analyses of the fish resources dynamics; 5) the countermeasures of fishery development and the protection of the rare freshwater fish.Lastly,the rational utilization, conservation and management of fishery resources are suggested.
