80年代以来,南海底层鱼类资源正在衰退,渔船单位功率产量逐年下降,而且大部分为低值下杂鱼,优质鱼只占10%,渔船生产效益低,以致一些底拖网渔般被迫停产或转产,拖网渔业潜在崩溃危机。另一方面,南海渔场尤其海南岛周围水域中下层鱼类资源(如带鱼、马鲛鱼等)有待开发利用的潜力很大,但传统的低口底拖网却无法捕获这些高水层鱼类。为了充分和合理地开发利用海南岛周围水域的中下层鱼类资源,我们聘
Since the 1980s, the resources of the bottom of the South China Sea have been declining. The power output per unit of fishing vessels has been declining year by year. Most of them are trash fish with low values. Only 10% of them are good fish. The fishing boats have low production efficiency and some bottom trawls are forced to stop production Or conversion, trawling potential crisis of collapse. On the other hand, there is great potential for development and utilization of fish stocks in the South China Sea fishery, especially in the waters around Hainan Island (such as octopus, mackerel, etc.), but the traditional low mouth trawls can not capture these high-water fish. In order to fully and rationally develop and utilize the middle and lower level fish resources in the waters around Hainan Island,
