Provide education and consultation for extension professionals, producers, and the public about aquaculture and water quality management. Design, plan, and conduct applied research projects and field demonstrations. Collaboratively facilitate the development of an aquaculture industry with the University of Kentucky Cooperative Extension Service, government agencies, and other organizations.

William A. Wurts is a Senior State Specialist for Aquaculture with the Kentucky State University Cooperative Extension Program. Recent work focuses on feeding practices, stabilizing water quality, and low-input production for freshwater shrimp and channel catfish. Past research includes applied physiology with marine, freshwater, and euryhaline species as well as effects of hardness and alkalinity on copper toxicity to aquatic life. His interests encompass sustainable aquaculture, growth biology, improving systems efficiency, and waste nutrient recapture through polyculture.
