几内亚比绍共和国海域经济渔获物种类组成及分布

On the composition and distribution of the economic aquatics caught in the sea waters of Guinea-Bissau Republic

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100～500／10范围内，存在一定数量浅水区罕见的底层类群，如须鼬鲥、长额拟对虾、真蛸、竹荚鱼、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（100～500m）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 distribution and composition of the aquatics caught in the sea waters of Guinea-Bissau Republic were investigated in 2006. The results showed that within the 100 -500 m depth water area, there were some deep-water aquatics with certain commercial fishing value, which were rare in the shallow waters, such as, Brotula barbata, Parapenaeus longirostris, Octopus vulgaris, Trachurus trachurus, Trachurus trecae, and Sparid etc. It is noteworthy that the China trawler fleets cooperated with the local organizations have caught fishes in Guinea-Bissau waters for 21 years, must leave from the shallow-water estuary fishing grounds as quickly as possible because where the fishery resources have been obviously declined, and divert towards the external waters gradually. For the China trawler fleets, there are without special difficulties to fish in 100 - 500 m water depth, but the equipment and installation of fishing vessels, for example, main turbine power, winch power, partial ship equipments, and fishing gears and fishing methods must be made some appropriate technological transformation. The problems related to the sustainable development of China distant-water fishery are herewith discussed.
