Abstract

Abstract The Atlantic Goliath Grouper (AGG), Epinephelus itajara, the largest Epinephelidae in the Atlantic Ocean, it is classified as critically endangered in Brazil. In the Brazilian northeast, studies focusing on the species are still incipient. Here we study the occurrence, habitat use, and spatial distribution of AGG in Alagoas (Brazil) by combining participatory methods, such as Citizen Science and Local Ecological Knowledge. Living individuals represented 64% (n = 85) of the records, while dead individuals were 36% (n = 47), with 14 records from illegal captures. Juveniles are common in estuaries and shallow natural coastal reefs, while adults are distributed in deeper areas on natural and artificial reefs. The occurrence was significantly higher on Alagoas’ southern coast. The São Francisco River (SFR) estuary stood out with 52 occurrences. We mapped 37 occurrence sites for AGG distributed along the coast, emphasising an artificial reef near SFR that received 12 reports about aggregations. The influence area of the SFR was indicated as a priority for species conservation due to the identification of a nursery and possible aggregations close to its mouth. We highlight the urgency of implementing short and long-term management actions along Alagoas’ coast.

保护大西洋歌利亚石斑鱼的知识联系:巴西热带海岸的记录

大西洋歌利亚石斑鱼(AGG)是大西洋最大的石斑鱼科，在巴西被列为极度濒危物种。在巴西东北部，对该物种的研究仍处于起步阶段。本文采用公民科学与地方生态知识相结合的参与式研究方法，对巴西阿拉戈斯州AGG的发生、生境利用和空间分布进行了研究。活着的个体占记录的64% (n = 85)，而死亡的个体占36% (n = 47)，其中14个记录来自非法捕获。幼鱼常见于河口和浅层天然海岸礁，而成鱼则分布在较深的天然和人工礁上。阿拉戈斯南部海岸的发病率明显更高。奥弗朗西斯科河(SFR)河口出现了52次。我们绘制了沿海岸分布的37个AGG发生地点，重点强调了SFR附近的人工礁，该人工礁收到了12份聚集报告。由于确定了一个苗圃和靠近其口的可能的聚集，SFR的影响区域被指定为物种保护的优先事项。我们强调在阿拉戈斯海岸实施短期和长期管理行动的紧迫性。

期刊介绍： Neotropical Ichthyology is the official journal of the Sociedade Brasileira de Ictiologia (SBI). It is an international peer-reviewed Open Access periodical that publishes original articles and reviews exclusively on Neotropical freshwater and marine fishes and constitutes an International Forum to disclose and discuss results of original research on the diversity of marine, estuarine and freshwater Neotropical fishes. -Frequency: Four issues per year published only online since 2020, using the ‘rolling pass’ system, which posts articles online immediately as soon as they are ready for publication. A searchable and citable Digital Object Identifier (DOI) is assigned to each article immediately after online publication, with no need to await the issue’s closing. -Areas of interest: Biology, Biochemistry and Physiology, Ecology, Ethology, Genetics and Molecular Biology, Systematics. -Peer review process: The Editor-in-Chief screens each manuscript submitted to Neotropical Ichthyology to verify whether it is within the journal’s scope and policy, presents original research and follows the journal’s guidelines. After passing through the initial screening, articles are assigned to a Section Editor, who then assigns an Associate Editor to start the single blind review process.
