Resumo: | The objective of the present study was to describe a set of lesions caused by entanglement of Sotalia fluviatilis accidentally captured by gillnet on July, 23, 1995, in the Northern Rio de Janeiro State (21º37'S-041º01'W), Southeastern of Brazil. The specimen presented lacerated lesions of the skin and subcutaneous tissue around the posterior extremity of the rostrum. Nylon twines were found associated to these lesions. Bone and teeth lesions were also observed in the underlying area and affected the maxillaries, pre-maxillaries and mandibles. The lesions were likely caused by non-lethal entanglement in fishing gears. Abnormalities in the growth layer pattern of the damaged teeth between the third and sixth growth layers suggest that this encounter had taken place when the specimen was around three years old. The data indicate that non-lethal encounters with fishing gears may cause serious health problems to small cetaceans and reduce their lifetime. This is the first description of fisheries-related chronic lesions in S. fluviatilis. |

O espécime apresentou lesões laceradas na pele e no tecido subcutâneo ao redor da extremidade posterior do rostro. Fios de náilon foram encontrados associados às lesões. Lesões ósseas e nos dentes foram também observadas na área subjacente e afetaram as maxilas, pré-maxilas e mandíbulas. As lesões provavelmente foram causadas por enredamento não-letal em aparelho de pesca. Anomalias no padrão de camadas de crescimento dos dentes lesados, entre a terceira e a sexta camada, sugerem que esta lesão ocorreu aos três anos de idade. Os dados indicam que encontros não-letais com redes de pesca podem causar sérios problemas de saúde em pequenos cetáceos. Esta é a primeira descrição de lesão crônica em S. fluviatilis relacionada a pescarias.Universidade de São Paulo.
