Abstract

Channa striata, commonly known as striped murrel, is an emerging species in Indian aquaculture having high consumer preference and market value. In the present study, six numbers of C. striata (500±100 g) reared in two different cemented tanks were noticed with
growth of heavy tumorous mass beneath bent vertebrae at the lateral side of the body cavity. Surgical excision revealed the presence of massive renomegaly, while, other vital organs appeared normal. Bacteriological and parasitological analyses revealed absence of any pathogen involvement in the tumorous mass formation. Further, histopathological analysis of renal tissue revealed compressed tubules, degenerative to necrotic changes in the tubular epithelial cells leading to sloughing of lumen, and infiltration of lymphoid cells and necrotic mass in the interstitium.
