摘要
2014年5(春)、7(夏)和9月(秋)明水期,分别在法别拉河入黑龙江河口设置张网、法别拉河河口注入黑龙江干流处固定4艘渔船、法别拉河达音炉段固定2艘舢板渔船,调查渔获物,以研究法别拉河鱼类种群结构及资源。结果发现:法别拉河共有鱼类59种,隶属2纲7目、16科,其中鲤科为主,占57.63%;鳅科占10.17%,鲿科占6.78%,鲶科与鲑科分别占3.39%,其他12科鱼类占18.64%。鱼类种群结构的变化是:大型鱼类占有比例减少,小型鱼类、鳜Siniperca chuatsi的占有比例增加。鳜及部分冷水性鱼类仍处濒危状态。
In order to study the population structure and stocks of fish in Fabiela River, a survey of fish samples collected was made separately by means of traps and fishing vessels disposed at Fabiela River mouth entering Heilongjiang River, fixing four fishing boats at the mouth of Fabiela River entering Heilongjiang River trunk stream and fixing two sailing junks in the Yinlu Section of Fabiela River in May, July, and September of 2014. There were fifty nine species in the Fabiela River, belonging to two classes＇ seven orders sixteen families, including Cyprinidae accounting for 57.63%, Cobitidae 10.17 %, catfish 6.78%, Cirrihitoidea and Salmonoidea separately 3.39 %.The species in other 12 families were accounted for 18.64 %. The variation of fish species was that the large-size fish was decreased while small-sized fish including mandarinfish（Siniperca chuatsi）were increased in percentage in the fish population structure. The mandarin fish and some cold water fishes were found to be in a state of endangerment.
