对几内亚比绍共和国(下称几比)海域渔获物种类组成及其分布进行了分析,认为几比海域水深100~500 m范围内,存在一定数量浅水区罕见的底层类群,如须鼬鳚、长额拟对虾、真蛸、竹筴鱼、鲷科鱼类等,具有一定的商业捕捞价值。文章指出,在几比海域合作捕鱼长达21年之久的中国拖网渔船队,必须尽快脱离资源业已明显衰退的浅水河口渔场,逐步向外发展。对中国渔船来说,实现深水捕捞(100~500 m)不存在太大的困难,但渔船设备(如主机功率、网机绞拉力、部分舾装设备)、渔具渔法宜作适当技术改造。文章还探讨了中国过洋性远洋渔业持续发展的有关问题。
The species composition and distribution of the catch species in the sea of Guinea-Bissau (hereinafter referred to as the “Bi-Bi”) are analyzed. It is concluded that there are a few bottom-layer taxa in shallow water areas within the depth of 100-500 m in the region of Guibi, , Long-legged shrimp, pomfret, pomfret, snapper, etc., has a certain commercial fishing value. The article points out that a Chinese trawler fleet that has been fishing for co-operation for more than 21 years in several seas must promptly step out from the shallow estuarine fishing grounds where resources have obviously declined. For Chinese fishing vessels, it is not too difficult for them to achieve deep-water fishing (100-500 m). However, appropriate technical improvements should be made to fishing vessel equipment (such as main engine power, net stranding force and partial outfitting equipment) and fishing gear fishing methods. The article also discusses the related issues of the sustainable development of the transboundary oceanic fisheries in China.
