About Us

Updated September 29, 2026

The La Crosse Fish Health Center: 

Established in 1962, the La Crosse Fish Health Center serves as the region’s primary resource for aquatic animal health. .The La Crosse Fish Health Center is housed within the Midwest Fisheries Center, which also includes the La Crosse Fish and Wildlife Conservation Office, Whitney Genetics Laboratory and administrative, GIS and outreach staff. The center provides comprehensive health inspections and diagnostic services to national fish hatcheries throughout the Midwest. Like all animals, fish are vulnerable to a range of environmental, nutritional, and infectious diseases, many of which can be fatal if not promptly addressed. Infectious diseases, those caused by pathogens such as parasites, bacteria, or viruses, are of particular concern because they can spread rapidly within hatcheries, between facilities during fish transfers, or to wild populations if infected fish are released.

Through surveys, inspections, and research, the center works to maintain the health of fish, freshwater mussel, and amphibian populations, supporting the long-term benefit of the American public. The center diagnoses illnesses in sick fish, helps prevent the spread of invasive species through its fish surrender program and grass and black carp ploidy analysis, and contributes to advancing scientific understanding of aquatic pathogens. Its staff are regional leaders in training biologists to assess fish health through their Fish Health Course.

The La Crosse Fish Health Center uses these policies and resources to guide their work:
