Small‐scale fisheries contribute substantially to the sustainability of coastal communities by providing livelihood and economic opportunities and ensuring food security. However, their geographic range of operation overlaps with that of industrial fisheries, increasing the resource competition, risk of vessel collision and inter‐sector conflicts, while jeopardizing the sustainability of fish stocks. When industrial vessels venture into waters that are reserved to artisanal fisheries, their operations become illegal. In Africa, the extent of such operations, beyond their legal implications, has resulted in severe economic, food security and maritime safety issues. In this paper, we use automatic identification system data derived from satellite technology to predict fishing operations and find that industrial fleets spend 3%–6% of their time fishing within inshore areas reserved for small‐scale fisheries between 2012 and 2016, of the total 4.2 million industrial fishing hours within the Exclusive Economic Zones of African countries. We assessed the total fishing effort by this form of illegal fishing operations at 166 million kWhours at least out of 4.9 billion kWhours in total. We discuss this dangerous form of illegal fishing, which often results in deadly collisions with small‐scale sector operators, increases competition and conflicts over fisheries access, threatens the sustainability of fish stocks, and calls for better governance, and protection.

将工业捕鱼入侵从太空赶入非洲近海

小型渔业通过提供生计和经济机会并确保粮食安全,为沿海社区的可持续发展做出了重要贡献。但是,它们的业务地理范围与工业渔业重叠,增加了资源竞争,船只碰撞和部门间冲突的风险,同时危害了鱼类资源的可持续性。当工业船冒险进入为手工渔业保留的水域时,其操作将变得非法。在非洲,此类行动的范围超出其法律含义,导致了严重的经济,粮食安全和海上安全问题。在本文中,我们使用源自卫星技术的自动识别系统数据来预测捕捞活动,发现在2012年至2016年间,工业船队将时间的3%–6%花费在为小型渔业保留的近海区域中,占总工业捕鱼量的420万非洲国家专属经济区的小时数。我们评估了这种非法捕捞活动的总捕捞努力量为1.66亿千瓦时,至少在总计49亿千瓦时中。我们讨论了这种非法捕鱼的危险形式,这种形式通常会导致与小规模部门经营者的致命冲突,加剧了竞争和渔业准入方面的冲突,威胁了鱼类种群的可持续性,并呼吁进行更好的治理和保护。
