In 1992, the UN banned the use of large-scale pelagic driftnets on the high seas (UNGA Resolution 46/215). Three decades later, however, drift gillnets remain one of the primary fishing gears in the Indian Ocean, accounting for approximately 30% of tuna catches in this ocean. Recent estimates indicate that several million small cetaceans have been killed in Indian Ocean gillnets over the past few decades. National agencies and the regional fisheries management organization charged with managing tuna fisheries, the Indian Ocean Tuna Commission, have yet to effectively document the bycatch of small cetaceans in these fisheries. Here, we review current information on cetacean bycatch in Indian Ocean drift gillnets and propose potential solutions to this important conservation issue.

流刺刺网渔业的兼捕：印度洋鲸类的水槽

1992年，联合国禁止在公海上使用大型中上层流网（联合国大会第46/215号决议）。然而三十年后，流刺网仍然是印度洋的主要渔具之一，约占该海域金枪鱼捕获量的 30%。最近的估计表明，在过去的几十年里，有数百万只小型鲸类在印度洋刺网中被杀死。负责管理金枪鱼渔业的国家机构和区域渔业管理组织印度洋金枪鱼委员会尚未有效记录这些渔业中小型鲸类的兼捕情况。在这里，我们回顾了印度洋漂流刺网鲸类兼捕的最新信息，并提出了这一重要保护问题的潜在解决方案。
