ABSTRACT

Este trabalho descreve a presença de resíduos antropogênicos no trato digestório de tartarugas marinhas no Litoral Norte da Bahia, Brasil. Foram realizadas necropsias no trato digestório de 45 tartarugas marinhas encontradas mortas (Chelonia mydas n=36; Eretmochelys imbricata n=9), no período de janeiro de 2006 a outubro de 2007. Em 60 por cento (27/45) das tartarugas necropsiadas foram encontrados resíduos, especialmente aqueles relacionados à atividade de pesca. Os resíduos encontravam-se ao longo de todo o trato gastrointestinal, com predominância no intestino grosso. A ingestão de resíduos pelas tartarugas marinhas do Litoral Norte da Bahia pode levar a debilidade e até mesmo provocar a morte destes animais.


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 percent 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 percent). The ingestion of debris by turtles from the Northern coast of Bahia may lead these animals to starvation, weakness and even death.
