DIEGUEZ FERNANDEZ, Lorenzo; RODRIGUEZ DE LA VEGA, Ricardo; VAZQUEZ CAPOTE, Raisa  and  CRUZ PINEDA, Carlos Alberto. Presence and distribution of Corbicula Fluminea (Müller, 1774) (Bivalvia:  Corbiculidae) in Camagüey, a probable molluscs competitor of sanitary interest. AMC [online]. 2007, vol.11, n.2, pp. 0-0. ISSN 1025-0255.

One-hundred eighty-nine malacologic researches were carried out in equal number of water bodies of Camagüey province, with the objective to know the current dispersal activity of Corbicula Fluminea, a bivalve with probable utilization as bioregulating, of other undesirable molluscs species. Its presence in lagoons, rivers, and small dams of Céspedes, Florida, Vertientes and Jimaguayú municipalities was reported, (30.8% of the total of municipalities), as well as in the 6.3% of the total sampled water bodies.  Jimaguayú contributed the 50% of the total habitat mirrors with presence of this clam.  The temperature (R=0.6286; R2=0.395, b=0.629; p<0.0414), was the only abiotic variable with important influence on the density of the mollusc. The theoretical model to calculate the abundance turned out to be density = ¬216.23 + 0.629 (temperature).

Keywords : cobircula; abiotic factors; mollusca; ecological studies; Cuba.
