Survey of parasites in sea turtles rescued off the coast of Santa Catarina and Paraná, Brazil (2020-2022) and their relationship with marine pollution.

The identification of parasite fauna can contribute to the assessment of the health status of sea turtles, and thus make it possible to develop effective management and treatment strategies aimed at conserving these animals. The present study aimed to investigate the parasite fauna in sea turtles rescued in six sections of the coast of Santa Catarina and Paraná (Brazil) from January 2020 to December 2022 through the recording of exam reports available in the Information System of Aquatic Biota Monitoring. In total, records of 334 sea turtles were analyzed during this period, of which 219 (65.
