We developed a regression model for predicting zebra mussel (Dreissena polymorpha) biomass from summer epilimnetic total phosphorus (TP) using published data from Polish lakes: dry tissue biomass = -10.8 + 11.0 log10TP, R2 = 0.19, P < o.04, n = 24. this model was used to predict Dreissena biomass in six recently-invaded North American lakes. All of the North American observations fit within the 95 % confidence limits of the Polish lake relationship. The predictive relationship for the combined Polish and North American data, dry tissue biomass = -7.1 + 9.0 log10TP, R2 = 0.24, P = 0.007, N = 30, should be useful as a necessary first step for predicting zebra mussel impacts, as well as for estimating reasonable stocking densities of zebra mussels for in situ experiments.
