Fish Diversity and Fish Assemblage Analysis in Shatiya Wetland of North Bihar

Abstract

The fish diversity of the wetlands has been decreasing during the last few years due to some extrinsic and intrinsic factors. The total number of fish species recorded so far during the present study is 47 at site 1 and 37 at site 2 belonging to 5 families. Cyprinidae is the most dominant family represented by major group species (12), intermediate group species (7) and minor group species (3) of high commercial value. Among these three groups, the diversity of fish species is higher in the minor group fish.
