Sea turtles undertake long migrations to feed, reproduce and nest. For this reason, they interact with many kinds of fisheries. The presence of stranded sea turtles on beaches may be used as an index of these interactions. The present study aimed to report sea turtles stranded along the coastline of Rio de Janeiro State, Brazil. GEMM-Lagos long-term monitoring programme has reported 57 stranded sea turtles since 1994, mostly of Chelonia mydas and Lepidochelys olivacea. None of them had tags or tag scars. Two individuals presented tumour-like growths. This kind of study and its continuity are very important due to the scarcity of published information on sea turtles in this area.
