Dinoflagellates display great diversity in tropical regions and play an important role in the complex microbial food webs of marine and brackish environments. The goal of this study is to identify planktonic dinoflagellates and their distribution in the estuary of the Maraú River, Camamu Bay, state of Bahia, in a region with increasing use of shellfish farming. Samples were carried out monthly from August 2006 to July 2007 at four stations along the estuary. Plankton was sampled with a 20 μm mesh net. We identified 20 dinoflagellate species. The greatest species richness was observed in the genera Protoperidinium (five spp.), Tripos (four spp.), and Prorocentrum (three spp.). Based on literature, six species were classified as potentially harmful: Akashiwo sanguinea, Dinophysis caudata, Gonyaulax spinifera, Prorocentrum micans, Scrippsiella cf. acuminata, and Tripos furca. Protoperidinium venustum was recorded for the first time in coastal waters of Bahia.

This study reports the occurrence and the effect of the environmental factors on the spatial and temporal distribution of the dinoflagellate Akashiwo sanguinea (Hirasaka) Hansen & Moestrup in estuarine waters of northeastern Brazil. Samples were collected at seven stations from March 2007 to February 2008 during high tide and low tide, using Van Dorn bottles. The samples were immediately fixed with Lugol and analyzed with the Utermöhl method. Water samples were also collected for the identification of the hydrological characteristics of the area. Akashiwo sanguinea occurred throughout the annual cycle and at all sampling sites with densities ranging between 5 and 410 x 103cells.L–1. The highest densities were recorded at low tide, especially during the months of the rainy season (July: 210 x 103 cells.L–1; August: 410 x 103cells.L–1). Density values were within the normal range and blooms were not detected. Despite being common in the area, the species showed preference for sites with high concentrations of orthophosphate and total dissolved phosphorus and with salinity in the mesohaline regime.
