In research, the term fisheries is interpreted broadly to include biological and ecological studies of fish, aquatic invertebrates, and other aquatic organisms as well as their interrelationships with each other, with humans, and with the physical environment. Completion of a research project is part of the learning experience of every graduate student, MS or PhD candidate, in Fisheries Conservation & Management. Most research projects are cooperative efforts with the USGS Arizona Cooperative Fish and Wildlife Research Unit and faculty in the School of Natural Resources and the Environment and faculty across campus who have expertise in aquatic organisms and ecosystems. Our research focuses on topics critical to management and conservation, especially the conservation of native desert fishes and invertebrates, biology and management of nonnative fish and invertebrates in the West, propagation of threatened and endangered desert fishes, temperature tolerances of Arizona fishes and potential impacts of global change, life history studies of fishes of the desert Southwest, and assessment of human impacts on inland aquatic ecosystems and species. Our research is funded by federal agencies (e.g., Fish and Wildlife Service, National Park Service, Bureau of Land Management, US Geological Survey, and Forest Service), by Arizona Game and Fish Department, and by non-governmental conservation organizations (e.g., The Nature Conservancy).
