Abstract

Biology of Gudusia chapra (Hamilton-Buchanan) from a floodplain wetland in West Bengal has been studied during 1999-2001. The fish is an omnivore, feeding mainly on Myxophyceae followed by Bacillariophyceae, Turbellaria
and Rotifera. November to March was the most active feeding period. The length weight relationship established for the fish suggested fairly isometric growth, closely following cube low. The regression equation obtained was Log W = 2.8576 Log L – 4.7564 (R2 = 0.9176). Fecundity of the fish ranged from 936
to 13,860. The ova diameter ranged from 0.05 to 1.28 mm. The fish has a prolonged breeding season, extending from March to October, during which it releases eggs in batches. The relative condition factor showed well being of the fish
