چکیده
The osteological and myological structures of the cephalic region and pectoral girdle of the Asiatic cat sh Heteropneustes fossilis are described and compared with those of several other cat shes, as the foundation for an analysis on the phylogeneticrelationshipsof the genusHeteropneustes. Our observation and comparisons support a close relationship betweenHeteropneustesand the clariid cat shes. More speci cally, the present study supports De Pinna’s 1993 study, according to which Horaglanis and Uegitglanis, two genera commonly included in the family Clariidae, are the sucessive sister-groupsof a monophyletic clade composed by the genusHeteropneustesand the remaining

Mass mortality of stinging catfish, Heteropneustes fossilis, was observed in a fish farm of Kulgaria, Burdwan in West Bengal, India. The cumulative mortality rates reached up to 5% of the total fish in the farm per day. The clinical signs of the affected fish showed ulcers on the skin which gradually grew in size and progressed to form ulcerous dermatitis. Clinical signs of catfish experimental...

The cephalic and pectoral girdle structures of Nematogenys inermis are described and compared to those of other catfishes, as the foundation for a discussion on the autapomorphies and phylogenetic relationships of the Nematogenyidae. Our observations and comparisons indicate that nematogenyids are defined, at least, by two unique, autapomorphic characters, namely : 1) anterior margin of prevome...
