摘要

海龟管理的一个重点是减少商业渔业中的兼捕渔获物,但可持续的消费捕捞也是许多国家的一个重要目标。确定不同渔业对海龟死亡率的影响程度有助于集中有限的管理资源。我们估算了所罗门群岛两种渔业的全国海龟捕获量:一种是小规模珊瑚礁渔业,捕获海龟是为了食用和销售;另一种是近海延绳钓渔业,海龟是副渔获物。延绳钓渔业的足迹遍布所罗门群岛的整个专属经济区,是小型渔业足迹的 67 倍。2018 年,两种渔业的总渔获量中位数为 12,000 只海龟,其中 85%-97% 的渔获量来自小型渔业。我们建议,所罗门群岛是一个拥有全球重要海龟繁殖种群的国家,其海龟管理应侧重于沿海小型渔业的可持续管理。

Contributions of small‐scale and longline fishing to sea turtle mortality in the Solomon Islands
A focus of sea turtle management has been reducing bycatch in commercial fisheries, but sustainable harvest for consumption is also an important objective in many nations. Identifying how much different fisheries contribute to turtle mortality could help focus limited management resources. We estimated national scale turtle catches for two fisheries in the Solomon Islands: a small‐scale reef fishery where turtles are caught for food and sale, and an offshore longline fishery where turtles are bycatch. The footprint of the longline fishery spanned the entire exclusive economic zone of the Solomon Islands and was 67 times bigger than the footprint of the small‐scale fishery. The median catch summed across both fisheries was ∼12,000 turtles in 2018, with 85%–97% of that catch in the small‐scale fishery. We suggest that turtle management in the Solomon Islands, a nation with globally significant turtle breeding populations, should focus on sustainable management of small‐scale coastal fisheries.

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.
