| Resumo: |
This study evaluated the relationships of certain allometric measurements in Melanoides tuberculatus Muller, 1774, in order to develop a statistical model to estimate the biomass of this mollusc species. We measured the total length and aperture of 70 shells. These measurements were correlated with the biomass values to construct exponential and power-function models, and both models showed high coefficients of determination. The exponential model was the better biomass predictor, with a coefficient of determination over 93%. These proposed models may be an effective tool to determine the biomass of M. tuberculatus in eutrophic Brazilian reservoirs.
