The air-breathing freshwater fish Clarias is represented by three species in the aquatic ecosystems of Kerala: Clarias batrachus Hamilton (the walking catfish), Clarias dayi Hora (Malabar catfish) and Clarias dussumieri Valenciennes (Valenciennes clariid). However, the populations of these species are declining sharply in Kerala and Clarias has became rare now. (Correspondence)
