Great Lakes Science Center

Program of Special Emphasis

USGS Great Lakes Science Center in Ann Arbor, Michigan, has studied the major adult fish populations in the Great Lakes for more than 50 years, providing resource managers at the U.S. Fish and Wildlife Service, the Great Lakes Fishery Commission, the Lake Committees, and others with annual estimates of forage fish biomass.  USGS scientists at the Great Lakes Science Center also conduct a wide variety of biological research in the Great Lakes basin addressing important species of concern such as lake trout, coaster brook trout, and lake sturgeon.  The Great Lakes Science Center is assisting the U.S. Environmental Protection Agency to develop and monitor "Indicators" of Great Lakes health and ecosystem integrity.  To accomplish these science missions, the USGS has the largest fleet of research vessels stationed throughout the Great Lakes.  The fleet consists of five large (45-107 foot) and several small (20-25 foot) vessels.  These vessels are equipped to sample fish, aquatic invertebrates, and water quality.  Laboratory facilities allow for the identification of taxa, quantification of prey abundance and diets, and water quality. USGS research divers assess biota and deploy underwater monitoring equipment.  Use of acoustic and other newly emerging technologies for fisheries research are helping to keep the science program at the Great Lakes Science Center healthy and vital.
