SUMMARY:

Sea turtles, ancient components of marine ecosystems, face significant population declines due to anthropogenic factors such as bycatch, pollution, and habitat degradation. Five of the world's seven species occur in Brazil, all of which are threatened with extinction. This retrospective study, based on 34 necropsies of sea turtles stranded on the coast of Pernambuco between October 2020 and February 2024, aimed to identify the causes of mortality and inform conservation actions. The research, conducted at the Animal Diagnostic Laboratory (LDA) of the Federal Rural University of Pernambuco (UFRPE), revealed that Chelonia mydas (green turtle) was the most affected species (58.82% of strandings in Porto de Galinhas), followed by Caretta caretta (loggerhead turtle) with 11.76%. Most strandings (76.47%) occurred in Porto de Galinhas, Ipojuca, Pernambuco, an area of intense tourism and fishing activity. Females (61.76%) and adults (73.53%) predominated among the cases, a worrying finding for conservation, given the impact of adult loss on population recovery. The main causes of mortality included pulmonary (18.60%), renal (13.95%), and gastric (13.95%) complications. Intestinal rupture due to foreign bodies/debris was diagnosed in 9.30% of cases, confirming marine debris as the direct cause of death. Pathologies such as granulomatous pneumonia caused by parasites (Spirorchiidae) and parasitic enteritis were also significant. The study reinforces the urgent need for waste management, sustainable fishing practices, and turtle health monitoring to conserve these endangered species on the Pernambuco coast.
