Entre setembro de 2007 e agosto de 2009, foram executadas excursões de campo as ilhas da Romana e Maiandeua na costa brasileira do Estado do Pará, para a coleta de espécimes dos quelônios aquáticos (Rhinoclemmys punctularia e Kinosternon scorpioides) em lagoas naturais, utilizando armadilhas do tipo covo (hoop-nets). 35 exemplares da cobra aquática Helicops angulatus, foram capturados acidentalmente nas armadilhas. Além de quelônios, este procedimento pode ser utilizado para a amostragem de populações de serpentes aquáticas.
Palavras-chave: Métodos de amostragem, lagoas naturais.
ABSTRACT
Between September, 2007, and August, 2009, a number of field excursions were conducted on the northern Brazilian coast (Romana and Maiandeua islands in the state of Pará) for the collection of specimens of freshwater turtles (Rhinoclemmys punctularia and Kinosternon scorpioides) in natural ponds. Where hoop-nets were used, a number of specimens of brown-banded water snakes, Helicops angulatus, were captured as bycatch in the traps. In addition to turtles, then, the procedure may be useful for the sampling of populations of aquatic snakes.
Key words: Sampling methods, natural ponds.
