Keywords:
Fish Disease, Mystus Vittatus, Fish Market, Histopathology, BangladeshAbstract
Diseases were investigated through clinical and histopathological observation of a catfish (Mystus vittatus) collected from three fish market of Mymensingh town and adjacent areas for a period of six months. Clinically, it was observed that Mystus vittatus were more affected showing scale loss, red spots, deep dermal ulcer in the months of December and January observed in Sankipara Railway Crossing and Gollpukurpar fish markets. The fishes showed no apparent disease symptom during October to November and February to March. Histopathologically, marked necrosis, pyknosis, haemorrhage and fungal granuloma were observed in skin and muscle. Gills of fishes from Sankipara Railway Crossing and Gollpukurpar markets were found to contain monogenetic trematode, hypertrophy, clubbing and pyknosis in December and January. Fish kidney and liver displayed fungal granuloma, necrosis, haemorrhage and vacuoles from Gollpukurpar market and Sankipara Railway market. The concerned species were found more affected by pathogen in Gollpukurpar and Sankipara Railway Crossing market than observed in the Kamal Ranjit market by during the months of December and January.
