Production of Viviparus viviparus (Mollusca, Gastropoda) in the Water Bodies of Ukrainian Polissya Zone
ABSTRACT
In the freshwater mollusk Viviparus viviparus, collected in the water bodies of the Ukrainian Polissya natural zone, characteristics of the annual production, based on various mass indexes (total mass, shell mass, mass of wet, dry and ash-free tissues) and P/B coefficient were determined. Portions were calculated of each age class into the total annual production. Multiple regression equations were obtained, enabling determination of different characteristics of the V. viviparus annual production on the basis of standard hydrobiological parameters - settlement density and biomass.
