非法和未报告的捕捞活动造成鱼类资源的过度捕捞，阻碍鱼类种群和生态系统的恢复。这项研究是第一次对非法和未报告的捕捞活动进行世界范围的分析。通过审查54个国家和公海的情况，我们估计，目前全世界非法和未报告的捕捞损失的总价值的下限和上限估计为每年100亿至235亿美元，相当于1100万至2600万吨。我们的数据具有足够的分辨率来检测过去20年非法捕捞水平和趋势的区域差异，我们可以报告治理与非法捕捞水平之间的显著相关性。发展中国家受到非法捕捞的威胁最大，西非的总估计渔获量比报告渔获量高出40%。这种程度的开发严重妨碍了海洋生态系统的可持续管理。虽然在减少某些地区的非法捕捞方面取得了一些成功，但这些事态发展是相对较新的，而且是在国际社会日益关注这一问题之后出现的。本文件提供了判断制止非法捕鱼行动是否成功的基线。
Illegal and unreported fishing contributes to overexploitation of fish stocks and is a hindrance to the recovery of fish populations and ecosystems. This study is the first to undertake a world-wide analysis of illegal and unreported fishing. Reviewing the situation in 54 countries and on the high seas, we estimate that lower and upper estimates of the total value of current illegal and unreported fishing losses worldwide are between $10 bn and $23.5 bn annually, representing between 11 and 26 million tonnes. Our data are of sufficient resolution to detect regional differences in the level and trend of illegal fishing over the last 20 years, and we can report a significant correlation between governance and the level of illegal fishing. Developing countries are most at risk from illegal fishing, with total estimated catches in West Africa being 40% higher than reported catches. Such levels of exploitation severely hamper the sustainable management of marine ecosystems. Although there have been some successes in reducing the level of illegal fishing in some areas, these developments are relatively recent and follow growing international focus on the problem. This paper provides the baseline against which successful action to curb illegal fishing can be judged.
