Abstract

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.

流刺网渔业的副渔获物:印度洋鲸目动物的沉没点
1992 年,联合国禁止在公海使用大型中上层流网捕鱼(联合国大会第 46/215 号决议)。然而,三十年后的今天,流刺网仍是印度洋的主要渔具之一,约占该海域金枪鱼渔获量的 30%。最近的估计表明,在过去几十年中,有数百万小型鲸目动物被印度洋刺网捕杀。国家机构和负责管理金枪鱼渔业的区域渔业管理组织--印度洋金枪鱼委员会--尚未有效记录这些渔业中兼捕小鲸类动物的情况。在此,我们回顾了目前有关印度洋流刺网误捕鲸目动物的信息,并提出了解决这一重要保护问题的潜在方案。

期刊介绍: Conservation Letters is a reputable scientific journal that is devoted to the publication of both empirical and theoretical research that has important implications for the conservation of biological diversity. The journal warmly invites submissions from various disciplines within the biological and social sciences, with a particular interest in interdisciplinary work. The primary aim is to advance both pragmatic conservation objectives and scientific knowledge. Manuscripts are subject to a rapid communication schedule, therefore they should address current and relevant topics. Research articles should effectively communicate the significance of their findings in relation to conservation policy and practice.
