摘要
2018年5月和11月,开展了独龙江流域渔业资源调查。结果表明,共采集到鱼类标本4种、73尾。独龙江鱼类结构较单一,裂腹鱼类是独龙江流域的绝对优势种,占渔获物总重的98.9%,占渔获物总数的97.2%。独龙江流域渔业资源自北向南呈现明显的增长趋势,下游的渔业资源远高于上游。为有效保护独龙江渔业资源,本文提出了加强基础性研究、异地保护、人工增殖放流、加大保护宣传与渔政执法力度等建议。
In May and November 2018, a survey of fishery resources in Dulong River Basin was carried out. The results showed that a total of 73 fish individuals belonging to 4 species were collected. The fish structure in Dulong River was relatively simple. Schizothorax was the absolute dominant species in Dulong River Basin, accounting for 98.9% of the total catch weight and 97.2% of the total catch. The fishery resources in Dulong River Basin showed an obvious growth trend from north to south, and the fishery resources in the downstream were much higher than those in the upstream. In order to effectively protect the fishery resources in Dulong River, this paper put forward suggestions, such as strengthening basic research, off-site protection,artificial restocking and release, and increasing protection publicity and fishery law enforcement.
