A Check List on Ichthyofaunal Diversity of Bahuda Estuary, Odisha, East Coast of India

Durga Prasad Behera, Lakshman Nayak and Satyabrata Das Sharma

The ichthyofaunal diversity of Bahuda estuary was studied during January 2012 to December 2012 from five stations. Sufficient work has not been done on the ichthyofaunal diversity from this estuary. The ichthyofaunal diversity samples were collected using different types of nets with the help of the local fishermen at monthly interval of time. There were 25 fish species observed under 2 classes, 6 orders and 18 families. The order Clupiformes was dominated contributing 30.08% followed by Mugiliformes (21.79%), Tetradontiformes (18.54%), Perciformes (15.45%), Siluriformes (10.41%) and Cypridontiformes (3.74%). The fish species Rastrelliger kanagurta was dominating contributing 13.01% followed by Mugil cephalus (11.38%), Thryssa kammlensis (9.76%), Mystus gulio (9.27%), Anchovilla indica (9.11%), Thryssa setirostris (7.32%) and Arius arius (7.15%). The marine fish species were highest at station 1 of the estuary as compared to brackish and fresh water species. The marine species were lowest at station 5 which is away from the mouth. The Margalef and Menhinik richness index ranged from 2.408-4.737 and 1.543-2.225, respectively which indicated high richness of organism in station 1 and moderate richness in station 5. The Shannon diversity index of this estuary varied between 2.114-2.863 which indicative that the estuary is less polluted.
