James S. Diana is Director of the Michigan Sea Grant College Program and Professor of Fisheries and Aquaculture at the School of Natural Resources and Environment (SNRE) at University of Michigan. He, his colleagues including Elizabeth LaPorte, and students are studying the Great Lakes. They research a variety of natural ecosystems, focusing mainly on native species, particularly pike and muskellunge. Dr. Diana has studied the behavior and ecology of temperate fishes for three decades, working extensively on the behavior and ecology of many temperate fishes, including pike, muskellunge, brown trout, lake sturgeon, yellow perch, largemouth bass, and alewives. They have also developed interests in aquaculture’s potential contribution to the global food supply through the understanding of ecologically sensitive aquaculture practices, particularly in developing countries.
