Abstract

Epizootic ulcerative syndrome (EUS) is considered to be an infection with an oomycete known as Aphanomyces invadans, commonly known as water molds causing heavy mortalities in wild and in farm fish. Large-scale fish mortality waters especially in the flood-affected fish farms in Kerala, following heavy rainfall and flood in August 2018 were reported. Subsequently, several fish disease cases were reported to ICAR-CMFRI by farmers, with characteristics of the invasive, tissue-destructive stages of EUS (Fig.1). In such cases reported, several species tested positive for EUS including Channa bleheri, and C. diplogramma. The affected fishes showed clinical symptoms like lethargy and lateral recumbency in rearing facilities. In some fish, the caudal peduncle, caudal fin or dorsal fins were severely eroded, and deep ulcers exposing the underlying musculature were also observed.
