First Record of Shortfin Mako Isurus oxyrinchus in the Brazilian Amazon Coast

The Shortfin Mako ( Isurus oxyrinchus ) is a pelagic species found in tropical and temperate waters worldwide. Despite being listed as Endangered on the International Union for Conservation of Nature (IUCN) Red List of Threatened Species, Shortfin Mako remains one of the most frequently captured species by industrial fleets and raising concerns about population declines. While interactions with oceanic fleets are well-documented, coastal captures of Shortfin Mako are less reported. In this study, we present the first record of a Shortfin Mako in the Brazilian Amazon Coast. The specimen was captured incidentally by artisanal fishers using a bottom longline at an approximate distance of 12 nautical miles from the shore. Given the challenges in sustainable fisheries and conservation along the Brazilian Amazon Coast and Shortfin Mako´s global vulnerability, comprehensive approaches, including co-participatory management are essential for better understanding the importance of the area for the species.
