Abstract

This study deals with the relative condition factor of feather back fish Notopterus notopterus (Pallas) in Jannapura pond, Karnataka. The fish specimens were collected during the period August 2002 to July 2003 and the total length and weight of both the sexes of fishes were recorded. The mean relative condition factor showed seasonal variation in both sexes. The mean relative condition factor value was found to be highest in April & lowest in December for both the sexes. The reduction in the Relative condition factor (Kn) during spawning phase may be because of the fish becoming exhausted due to spawning activity. The condition of the fish was coincided with the maturation stage of the fish.The mean Kn values for different months and length groups indicated good conditions of the fishes.
