Studies on Red Spot Disease of Pond Cultured Eels—III

A Case of the Disease in the European Eels (Anguilla anguilla) Cultured in Tokushima Prefecture

Abstract

In 1974, red spot disease (Pseudomonas anguilliseptica infection) occurred in the European eels cultured in Tokushima prefecture.
A remarkable petechial hemorrhage in the skin of the mouth region, operculla and ventral side of the body which are known to be typical external symptoms of the disease, were not so evident and the damage was not so serious as in the Japanease eels (A. japonica).
