改革开放以来,南海区底拖网渔业迅猛发展,大功率拖网渔船数量不断增加,拖网渔业总产量连年增长。然而底鱼资源却遭受严重的捕捞压力,许多经济鱼类资源随之日趋衰退,导致渔船单位功率产量趋于下降,渔船经济效益不佳。但是,据调查发现南海中层水域,尤其海南岛周围水域,中层鱼类的捕捞潜力依然巨大,可是 Since the reform and opening up, the bottom trawl fishery in the South China Sea has been booming. The number of high-powered trawlers has been steadily increasing, and the total trawl fishery output has been growing year by year. However, the bottom fish resources have been subjected to severe fishing pressure. As a result, many economic fish resources have been declining with each passing day, resulting in a decrease in unit power output of fishing vessels and a poor economic efficiency of fishing vessels. However, according to the survey, the catch potential of middle-level fish remains huge in the middle waters of the South China Sea, especially in the waters around Hainan Island. However,
