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.

所罗门群岛小规模和延绳钓捕鱼对海龟死亡率的影响


海龟管理的重点一直是减少商业渔业中的副渔获物，但可持续捕捞以供消费也是许多国家的重要目标。确定不同的渔业对海龟死亡率的影响程度可能有助于集中有限的管理资源。我们估计了所罗门群岛两个渔业的全国规模海龟捕捞量：一个小规模的珊瑚礁渔业，捕捞海龟用于食用和销售，以及近海延绳钓渔业，海龟被兼捕。延绳钓渔业的足迹跨越了所罗门群岛的整个专属经济区，是小规模渔业足迹的 67 倍。2018 年，这两个渔业的渔获量中位数约为 12,000 只，其中 85%-97% 的渔获量来自小规模渔业。所罗门群岛是一个拥有全球重要海龟繁殖种群的国家，我们建议海龟管理应侧重于小规模沿海渔业的可持续管理。
