Aquatic Animal Diseases

Information on diseases that pose a significant threat to commercial aquaculture industry sectors in the U.S.

Infectious diseases affect cultured aquatic animal populations similar to the impacts seen in other livestock sectors; loss of production, increased costs associated with treatment, and loss of trade or markets.   APHIS encourages aquaculture producers to work with aquatic animal veterinarians and other aquatic animal health experts to address health issues on the production site.

APHIS encourages the reporting of detections of all OIE-listed aquatic animal diseases to state animal health officials (SAHO).  For a list of the current OIE-listed diseases reporting to USDA APHIS click here

Infectious Salmon Anemia Virus (ISAV)

ISAV, or more commonly "ISA" is a viral disease that causes severe anemia in infected fish. It affects farmed and wild Atlantic salmon in several areas of the world. APHIS works with fish health partners to help protect U.S. aquaculture and wild fish populations from this disease.
