Abstract

The present paper gives a comparative picture of the biology of Nandus nandus (Hamilton), a critically endangered fish of West Bengal, in its natural habitat and in the fish genetic resource centre set up at the new alluvial zone of West Bengal. In the new alluvial zone of W. Bengal many indegenous species of
fishes have undergone decline in their population and Nandus nandus (Hamilton) is one among them. Samples were collected from Mogra beel at Birohi, Nadia district and released at the Fish Genetic Resource Centre of RRS, Gayeshpur, BCKV.
It has been observed that the general biological condition of Nandus nandus collected from Gayeshpur pond ( Fish Genetic Resource Centre ) was better than the fish collected from its natural habitat, Mogra beel as indicated by higher values of b, K, Gastro-somatic index, gonado-somatic index and
fecundity. This shows that the fish adapted very well to the conditions of the Gayeshpur pond and showed better growth than its natural habitat of Mogra beel. This may be due to the better environmental conditions and food availability in the Gayeshpur pond.
