Research at the La Crosse Fish Health Center
Service aquatic animal health professionals may conduct applied research on aquatic animal diseases to:
(1) Improve pathogen detection and disease diagnostic techniques;
(2) Develop procedures for hygiene, therapy, disease prevention, and pathogen eradication;
(3) Improve the disease resistance of cultured aquatic animals; and
(4) Study the prevalence and impact of diseases in free-ranging aquatic animals.
