摘要：

为了解黑龙江抚远江段渔业资源现状。于2009年5月、9月和2010年7月，分3次共26天对黑龙江抚远江段用定置张网截捕、迷魂阵捕捞和走访渔民购买渔获物的方法进行鱼类调查，初步研究了黑龙江抚远江段鱼类种类、分布及物种多样性。结果表明：在该江段共发现鱼类49种，隶属于8目14科38属，多为中底层小型鱼类，其中蛇鮈(Saurogobio dabryi)、湖鱥(Phoxinus percnurus)和黄颡鱼(Pelteobagrus fulvidraco)为优势种类，并且该江段内鱼类种类具明显的季节性变化，春、秋季种类多于夏季。说明黑龙江抚远段鱼类多样性较低，将本次调查结果与历史资料比较后发现，该江段内鱼类的种类减少了1目7科27种，表明黑龙江抚远江段鱼类物种多样性遭到破坏，亟待保护。

Abstract:

Through field investigation lasting 26 days in May, September of 2009 and July of 2010 with the way of trapping, catching and buying. we studied the fish species, distribution and diversity. in order to know the fish resource status in the Fuyuan section of Heilongjiang River. The results showed that there were totally 49 species of fish belonging to 38 genera, 14 families, 8 orders in this river. Most of them were small mesopelagic or demersal fish and Saurogobio dabryi, Phoxinus percnurus and Pelteobagrus fulvidraco are dominant species. comprised with other studies, species diversity level and population number of fishes in this river are lower, and 27 species, 7 families and 1 orders of fish have been absented. It has been suggested that fish species diversity has been damaged and the fish resources should be utilized reasonable and conservation in the Fuyuan section of Heilongjiang River.
