And that's huge problem, because IUU fishing is a major environmental problem and an economic challenge.

这个问题非同小可，因为这种捕鱼行径不仅会引起巨大的环境问题，还会挑战经济发展。

That's because illegal, unreported and unregulated fishing, or IUU, is enormously profitable, raking in billions of dollars globally.

原因是不合法、不汇报、不合规的捕鱼行径（IUU）在全球范围内牟取暴利，体量高达数十亿美元以上。

Illegal, unreported and unregulated fishing – or IUU – not only causes economic damage, but is a threat to food security and biodiversity.

非法、非法、不报告和无管制捕捞活动(IUU)不仅有害经济，还是粮食安全和生物多样化的一大威胁。

Indeed, over the years, we have seen how large-scale IUU fishing operations can drive down populations of some of the world's most lucrative fisheries to dangerously low levels.

而在过去这些年中，我们确实目睹了这种大规模的捕鱼行径是如何让一些世界为人类带来收益的鱼类资源濒危殆尽的。
