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

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.
