Condition of Dreissenids in Western Lake Erie and Lake Michigan

The introduction and expansion of dreissenid mussels (zebra and quagga  mussel) has led to large-scale changes in nutrient dynamics and food  webs in the Great Lakes.  A fundamental need in assessing present and  potential impacts is knowledge of dressenid abundance and biomass, and  rates of population change.  The latter can be predicted by examining  trends over time, and by assessing the relative physiological  condition of the population.  This project will examine the  physiological condition of dreissenids in western Lake Erie. For  perspective, comparisons will be made to the condition of mussel  populations in Lake Michigan.
