Diversity of Fishes: Table 2 revels that about three dozen Fish varieties are found in the mongra barrage, a fresh water man- made reservoir. All these varieties have been grouped into four categories viz, abundance common, moderate and rare, based on the local fishermen’s netting observations. Of the four categories, the category of common species found in the barrage covers the largest share of 39.39%, i.e. two- fifths. The abundance category occupies the second position with 24.24%, which is closely followed by the rare category. Surprisingly, the least number of species are seen in the moderate category. So far as the diversity of fish is concerned, table 2 amply demonstrates that mongra Barrage is rich in fish diversity. This diversity is more pronounced in terms of order of species in the rare category, while it is least diversified in the abundance category. Diversity of fish in terms of family more or less follows the similar pattern. 2 Mongra Barrage: Diversity of Fishes – Nature of IUCN No. and Names of Genus & Species S.
