Density and biomass of D. delodontus expansus (Kuster, 1856) (Mollusca, Bivalvia) were estimated in the Reservoir of the Rio Pardo (Botucatu, Sao Paulo, Brazil), in December, 1982. The average population density of the bivalves in the reservoir was 36.62 specimens.m-2, at 98 sampling stations. Total density in the reservoir was estimated at 5.8 million individuals. Average biomass was 347.27 g.m-2 (alcohol weight); 225.00 g.m-2 (shells dry weight) and 10.92 g.m-2 (bodies dry weight). Total biomass in the reservoir was estimated at 55.0 tons (alcohol weight), 35.6 tons (shells dry weight) and 1.7 tons (bodies dry weight). The granulometric analysis of the sediment showed that silt presented greater correlation with biomass and density (r = 0.16), though unsignificant. The other fractions of sediment (sand and clay) showed lower correlation coefficients with density and biomass of the bivalves. The granulometric composition of the sediment was not related with density and biomass of the animals. A revision of other ecological factors showed that there are no limiting factors on the distribution and abundance of bivalves in the reservoir. This explains problaby th high values of density and biomass. |
