Development of the Great Lakes quagga mussel DEB bioenergetic model will: 1) improve effectiveness of nonpoint source nutrient control and refine management efforts, and 2) address a cross-focus area science priority by enabling biophysical models used to support nutrient management decisions to better predict impacts of quagga mussels on promoting HABs through selective feeding, nuisance algae (e.g., Cladophora) through enhancing water clarity, HABs and nuisance algae through nutrient excretion, and controlling phytoplankton abundance and productivity. In addition, by incorporating a state-of-the-art quagga mussel bioenergetic model, biophysical models will be able to better connect nutrient inputs from specific watersheds to nearshore and lake-wide ecosystem status objectives, and thereby improve targeting of management and restoration actions in watersheds that will have the greatest impact.
