摘要

太平洋石斑鱼（Epinephelus quinquefasciatus）是东太平洋热带地区最大的珊瑚礁鱼类。由于缺乏种群数据以及捕捞带来的风险，世界自然保护联盟将其归类为数据不足类。利用渔民的当地生态知识，我们评估了巴拿马太平洋沿岸太平洋石斑鱼的历史捕捞趋势。从 1958 年到 2018 年，手绳和鱼叉捕获的太平洋鳞石斑鱼平均重量显著下降。市场需求和环境退化被认为是太平洋石斑鱼产量下降的主要驱动因素。当地生态知识表明，可以获得有价值的渔业信息，并用于了解物种的种群趋势。

Local Ecological Knowledge as a Conservation Tool for Identifying Threats to the Pacific Goliath Grouper (Epinephelus quinquefasciatus) in Panama

The Pacific goliath grouper, Epinephelus quinquefasciatus, is the largest reef fish of the tropical Eastern Pacific. The IUCN categorizes it as Data Deficient because of the lack of population data and the risk posed by fishing. Using fishers' local ecological knowledge, we assessed Pacific goliath grouper historical catch trends along Panama's Pacific coast. Handline and speargun catches showed significant declines in the average weight of Pacific goliath grouper landed from 1958 to 2018. Market demand and environmental degradation were identified as primary drivers of the Pacific goliath grouper perceived decline. Local ecological knowledge demonstrated that valuable fisheries information can be derived and used to inform species' population trends.

期刊介绍： Aquatic Conservation: Marine and Freshwater Ecosystems is an international journal dedicated to publishing original papers that relate specifically to freshwater, brackish or marine habitats and encouraging work that spans these ecosystems. This journal provides a forum in which all aspects of the conservation of aquatic biological resources can be presented and discussed, enabling greater cooperation and efficiency in solving problems in aquatic resource conservation.
