Abstract

Coastal environments, such as bays, are essential to the development of fishery resources due to their economic and ecological importance. This paper presents an updated checklist of coastal marine fishes as part of a long-term monitoring program in Aratu Bay (2014–2024), Bahia state, eastern Brazil. A total of 109 species belonging to 58 families and 24 orders were cataloged. Five endemic species and ten species listed as at risk according to the IUCN criteria (from Vulnerable onwards) were identified. The Carangidae was the most representative family in terms of species number, followed by Gobiidae and Sciaenidae. The ichthyofauna was dominated by mobile invertebrate feeders and macrocarnivores. Two non-native species were observed in the region: the Muzzled blenny, Omobranchus sewalli and the mud sleeper Butis koilomatodon. Aratu Bay supports a diverse ichthyofauna with diverse trophic guilds and habitats, rendering it an important area for the feeding and development of economically valuable species, including those facing threats.

巴西东部阿拉图湾鱼类动物的最新核对表、特征和保护现状
海湾等沿海环境因其经济和生态重要性而对渔业资源的开发至关重要。本文介绍了作为巴西东部巴伊亚州阿拉图湾长期监测计划(2014-2024 年)一部分的最新沿海海洋鱼类名录。共有 109 个物种被编入目录,隶属于 58 科 24 目。根据世界自然保护联盟(IUCN)的标准(从 "易危 "到 "濒危"),确定了 5 个特有物种和 10 个濒危物种。就物种数量而言,鲤科是最具代表性的科,其次是戈壁鱼科和鲷科。鱼类动物以移动的无脊椎动物和大型肉食动物为主。在该地区观察到两种非本地物种:匙吻鲟(Omobranchus sewalli)和泥睡鲈(Butis koilomatodon)。阿拉图湾有多种多样的鱼类动物,其营养行会和栖息地各不相同,使其成为具有经济价值的物种(包括面临威胁的物种)觅食和发展的重要区域。
