Welcome to the Fish Health Section of the American Fisheries Society

The Fish Health Section (FHS) is one of the largest and most international sections of the American Fisheries Society. The FHS was formed in 1972 to give fish biologists, diagnosticians, researchers, aquaculturists, veterinarians, administrators, and others involved in fish health, an organization for communication and interaction.

Fish Health Laboratory QA/QC Program

The Standing Committee for Quality Assurance has unveiled plans for a multi-tiered program for quality assurance and quality control in aquatic animal laboratories. Details of the initial phase of the program, designated as "Tier 1 - Prequalification", have been finalized and the application can be accessed via (Application). A second phase, "Tier 2 - Recognition" is under development and should be completed by the end of the year. The first two phases will be administered by the FHS, under the guidance of the Standing Committee. Possible future plans might include a third Tier, with actual accreditation under an agency with legal authority.

An application fee for the Tier 1 phase of $500 has been established .For additional information, contact Dr. Chris Wilson at wetvet53@gmail.com
