Fish Diversity
Fourteen species of fi shes belonging to 12 genera, 6 families and 3 orders have been recorded in
Sat Beel (Kar 1998 ):
Amblypharyngodon mola, Cyprinus carpio
carpio, Labeo calbasu, Puntius chola, Puntius
ticto, Lepidocephalichthys guntea, Mystus
bleekeri, Mystus vittatus, Sperata seenghala,
Ompok bimaculatus, Wallago attu, Clupisoma
garua,, Channa punctatus and Macrognathus
pancalus.
Fish Yield (FY)
Weed fi shes are quite abundant because the wetland is a victim of eutrophication. Channa spp.
revealed good yield (30 %) followed by other
fi shes, namely , Puntius spp. (20 %), A. mola
(15 %) and Mystus spp. (20 %). The big size
fi shes account for approximately 15 % of the fi sh
yield.
