Anacystis marina

Mortalities of channel catfish, Ictalurus punctatus, have been atfributed to ingestion of toxic blooms of Microcystis aeruginosa (Zimba et al., 2001). The mortalities followed sudden temperature drops of 5°C and necropsy of fish revealed congested hver and spleen tissue, which indicated microcystin toxicosis. Other channel catfish farms in southeastern United States using brackish well water have experienced fish kills that have been reported to be associated with thick blooms of a halophytic cyanobacteria, Anacystis marina rather than Microcystis (Snyder et al., 2002).
