Gastropods from Camamu Bay, state of Bahia, Brazil

Abstract

The present study provides a species list of marine and estuarine gastropods from Camamu Bay, in the state of Bahia, northeastern Brazil. Expeditions to collect mollusks were carried out between 2003 and 2006 in Acaraí River estuary, using a trawling boat with otter trawl. A total of 3,193 gastropod specimens were identified, belonging to 46 families, comprising 94 species. Amongst the recorded species, all represent the first occurrence to Camamu Bay and four to the state of Bahia (genera Littoridina, Morula and the species Cadlina rumia and Polystira albida).

The samples of gastropod mollusks were collected on
unconsolidated substrate using a trawling boat with one
or more parallels trawls kept apart horizontally by otter
boards with 3 cm of net mesh size and a 4 m mouth. In
each collection point, the trawling lasted about 10 minutes.
