摘要： 海洋渔业（尤其是小型海洋渔业）为世界各地的沿海居民提供了重要的食物来源、就业、经济收入。西非临近海域是世界上海洋渔业资源最丰富的地区之一，在西非沿海地区数百万居民以捕鱼为生，然而，西非众多捕鱼区却是最贫穷的地区。在全球化不断推进的今天，非法捕捞已严重威胁到海洋生态系统安全。西非临近海域的非法捕捞问题尤为严峻。在整合相关文献资料的基础上，分析了非法捕捞的主要影响，并对西非地区的非法捕捞现状和问题进行了讨论，认为部分欧盟国家是非洲西部海洋渔业资源主要非法捕捞者，西方学者认为中国是西非地区主要的非法捕捞者是不符合事实的。非法捕捞的根本原因是持续的鱼类需求和捕捞活动缺乏控制，提出了西非非法捕捞的应对措施，以期有助于解决西非非法捕捞问题。
