一、前言南海鱼类资源特点是:分布广、品种多、繁殖力强、生长周期短、交替补充能力强;沿岸渔场已充分利用,外海渔场潜力很大.150～200米水深鱼类分布密度为4.1吨/公里~2,总储量为86.4万吨.目前捕捞只有3万吨左右,估计捕捞可达30万吨,不会造成捕捞过度.因此广东海洋捕捞渔业的方向是:巩固发展深海渔业,积极利用外海资源.深海拖网渔船是今后海洋捕捞渔业发展的重点.而在深海拖网渔船中,木质拖网渔船又占绝大部分,因此
I. Introduction The fish resources in the South China Sea are characterized by wide distribution, large variety, strong fertility, short growth cycle and strong alternation ability. The coastal fishery has been fully utilized and the potential of the offshore fishery is very high. The distribution density of fish at 150 ~ 200 m depth With a total reserve of 864000 tons.At present the fishing is only about 30000 tons, the estimated fishing up to 300000 tons, will not cause excessive fishing.Therefore, the direction of Guangdong marine capture fisheries is: to consolidate the development of deep-sea fisheries , And make active use of the resources of the sea.The deep-sea trawlers are the focus of the development of marine capture fisheries in the future, while in the deep-sea trawlers, the majority of wooden trawlers account for
