摘要:
2003-2004年在汉江中游江段共监测654船次,统计渔获物6914.16 kg,生物学测定1682尾鱼,共采集鱼类78种,隶属18科58属.目前汉江中游渔获物组成和结构与20世纪70年代相比发生了较大变化,翘嘴红鲌、瓦氏黄颡鱼、鲶、鲢、黄尾鲴、大鳍蠖等在渔获物中比例已经很少;草鱼资源也明显下降;铜鱼、青鱼、蒙古红鲐、鳡、细鳞斜颌鲴、吻鮈、长吻鮠、拟尖头红鲌、鳙、鳜等在渔获物中已基本消失;而鲤、鲫、黄颡鱼、长春鳊、赤服鳟等中小型鱼类在渔获物中的比例却相对上升;渔获物中个体大的鱼减少,低龄鱼及幼鱼个体比重增加.与70年代资料相比,汉江中游鱼类资源已呈衰退趋势.

Abstract:
In the years 2003-2004, a survey on the fisheiy status was taken in the middle reaches of the Hanjiang River. A total of 654 boats were investigated, 6914.16kg fish catch were collected and 1682 tails of fish were measured. Fishes were belonging to 18 families, 58 genera and 78 species. In comparison with the relevant data in I970's, fish catch composition and structure had more change at present time. For example, the ratio and quantity of Culter ilishaeformis (Bleeker), Pelteobagrus vachelli (Richardson), Silurus asotus Linnaeus, Hypophthalmichthys molitrix (Cuvieret Valenciennes), Xenocypris davidi Bieeker, Mystus macropterus (Bleeker) and Ctenopharyngodon idellus (Cuvier et Valenciennes) in fish catch had been greatly decreasing. Some fishes such as Coreius heterodon (Bleeker), Mylophxiryngodon piceus (Richardson), Culter mongolictis (Basilewsky), Elopichthys bambusa (Ric hardson), Xenocypiis microlepis Bleeker, Rhinogobio typus Bleeker, Leiocassis longirostris Gtinther, Erythroculter oxycephaloidaes (Kreuenberg et Pappenhein), Aristichthys nobilis (Richardson), and Siniperca chualsi (Basilewsky) had disappeared in some degree. However ihe number of medium and small-sized fish, such as Cyprinus (Cyprinus) carpio Linnaeus, Cyprinus carassius Linnaeus, Pelteobagrus fulvidraco (Richardson), Parabramis pekinensis (Basilwsky), Squaiiobarbus curriculus (Richardson) and so on had been increasing. Amongst fish calch, the number and ratio of low-aged flsh and adolescent fish had been increasing, and at the same time big-sized fish decreasing, On the basis of the facts above, there can be concluded that the fishery resources in the middle reaches of the Han-jiang River has been declining.
Key words:  Fish resources  the Hanjiang River  section in the middle reaches
