Estudo experimental dos Teredinidae Rafinesque, 1815 (Mollusca: Bivalvia) do estuário da Lagoa da Tijuca, Rio de Janeiro, RJ, Brasil

Purpose the systematic survey of the Teredinidae present at the estuary of Lagoa da Tijuca, RJ, Brazil; the caracterization of the area concerning the activity of these organisms and the analysis of the spatial distribution of the present species according to the gradient of salinity. Using experimental panels composed of pinewood sheets (Araucaria angustifolia (Bertol) o. Kuntze) in 5 stations, seven species of Teredinidae were found: Lyrodus floridanus (Bartsch, 1922); Teredo navalis Linnaeus, 1758; Teredo furcifera Martens, 1894; Teredo bartschi Clapp, 1923; Bankia fimbriatula Moll & Roch, 1931; Bankia gouldi (Bartsch, 1908) and Bankia carinata (Gray, 1827). It was elaborated figures, description and keys to the identification of all species found out. Lagoa da Tijuca seemed to be an area of moderate activity of Teredinidae. The results also showed the existence of a possible seasonal change regarding mainly to the atmospheric precipitation and to the consequent variation of salinity. We noticed a decrease in the number of species and specimens as we entered the lagoon. The spatial distribution is discussed for each specie. We also discussed the 0influence of other factors such, as temperature and fouling.
