Dr. John Hawke has been involved in fish health research and diagnostics for over 25 years and has been a member of the faculty of the Department of Pathobiological Sciences since 1997. As Chief Diagnostician of the LADL he has been involved in the processing of aquatic disease submissions from over 25 different states involving over 100 different aquatic species over the last ten years. The lab provides diagnostic services to commercial aquaculturists, state fisheries biologists, researchers, bioassay laboratories and ornamental fish keepers.
Dr. Hawke is currently the Vice President of the Fish Health Section of the American Fisheries Society, and is co-Chair of the Working group on Aquaculture of the Subcommittee on Veterinary Antibiotic Susceptibility Testing of the NCCLS. He is also a member of the Research Committee of the School of Veterinary Medicine and participates in the Cooperative Aquatic Animal Health Research Program (CAAHRP) and the Multidisciplinary Program in Infectious Disease.
Research Interests
Dr. Hawke is currently conducting research and directing graduate students in research on emerging infectious diseases of cultured marine and freshwater fish. Specific areas under investigation include: pathogenesis and vaccine development for photobacteriosis caused by Photobacterium damselae in hybrid striped bass; pathogenesis and epizootiology of the oomycete Aphanomyces invadans in catfish and bluegill; non-lethal detection methods for largemouth bass virus disease; and improved diagnostic methods for Photobacterium damselae, Flavobacterium columnare and Edwardsiella ictaluri including molecular and biochemical characterization of strains from different fish species.
