Ingestão de resíduos antropogênicos por tartarugas marinhas no litoral norte do estado da Bahia, Brasil

Abstract

This study investigates the presence of anthropogenic debris in the digestive tract of sea turtles in the Northern Coast of Bahia, Brazil. Necropsies were performed on 45 turtles, 36 green turtles (Chelonia mydas) and 9 hawksbills (Eretmochelys imbricata), found dead between january 2006 and october 2007. Debris was found in 60% of the animals, especially those related to fishing activities. Litter could be found throughout the entire gastrointestinal tract, but it was found predominantly in the large intestine (47.53%). The ingestion of debris by turtles from the Northern coast of Bahiamay lead these animals to starvation, weakness and even death.
