Fish diversity and fish community analysis in ponds of Saran district in Bihar

Abstract

The fish diversity of the ponds 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 Pond 1 and 37 at Pond 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.
