Abstract

Length-weight relationship, condition factor and relative condition factor of climbing perch (Anabas testudineus, Bloch) were studied over a period of eleven months from April 2007 to February 2008. A total of 297 fish samples were collected from Khulna and Bagerhat districts. The length-weight relationship of A. testudineus was linear and the equations for total length-body weight and standard length-body weight were (r²=0.94) and (r²=0.94), respectively. The coefficient of correlation indicates that the relationship between length and weight of the fish was highly significant. The maximum and the minimum values of the condition factor were 24.594 (body weight 26.1 g) and 17.809 (body weight 18.9 g), respectively with the mean value of 20.522±1.248. The relative condition factor varied from 0.883 (body weight 12.7 g) to 1.225 (body weight 26.1g) with the mean value of 1.014±0.061.
