Interpretive Summary: Toxin producing algae have been documented in numerous catfish, striped bass, tilapia, and commercial minnow facilities. A review of available information suggests that microcystin, anatoxin-a, and prymnesin toxin are most common in these systems. General properties of each toxin are discussed as well as the impacted aquaculture species.

Technical Abstract: Toxin-producing algae are common in aquaculture facilities. Three divisions of algae have been identified as producing toxins: cyanobacteria, prymnesiophytes, and euglenoid algae. Cyanobacteria produce the most diverse forms including hepatic and neurologic forms. Prymnesin toxin is confined to saline production ponds, and is expanding northward.
