Abstract:Twenty-five species of fishes belonging to 18 genera, 7 families under the order siluriformes have been recorded from different freshwater and brackish water wetlands of South West Bengal, India. Fishery potential of 17 commercially important siluroid fishes were noted especially from market surveys as well as from information collected from local fishermen communities. Following the IUCN guidelines, and also through Participatory Rural Appraisal (P.R.A.) methods, an attempt has been made to assess the conservation status of such fishes, many of which are thought to be threatened. Trend analysis, Fish Magnitude Value and Rank based Quotient revealed the threatened status of 17 siluroid fishes.
