A Review on Ichthyofaunal Diversity and Distribution of North-East India

Abstract

The present communication reviews the ichthyofaunal diversity of the North-east India. Eastern Himalayas
are one of the biodiversity hotspots in India and harbour very diverse fi sh fauna. The biodiversity richness of
the north east India has attracted many taxonomists to explore fi shes and have reported diff erent views on the
number of fi sh species from this area. This study compiles all the previous studies and found the icthyodiversity
to be a total of 512 fi sh species from 128 genera, 40 families and 12 orders. But about 16% of fi sh diversity in
North-East India comes under the threatened category for which proper conservation measures are desirable and
about 33% of fi shes come under the data-defi cient (DD) and not-evaluated (NE) categories and their conservation
status needs more attention.
