Abstract
In October 1982, a bacterial disease occurred among cultured young flounder, Paralichthys olivaceus, in the Kurida Bay, Kyoto Prefecture. The diseased fish showed abdominal inflation and accumulation of ascites.
Bacteria isolated from the diseased fish were identified as Edwardsiella tarda.
The pathogenicity of the isolate for flounder and yellowtail, Seriola quinqueradiata, was proved positive by intra-peritoneal and/or intramuscular injections.
