Abstract/Description: | The biological parameters like length-weight relationships, relative condition factor, gonado-somatic index were examined of 348 specimens of Channa punctata (Bloch, 1793) from wetlands of Nadia district, West Bengal. The total length of the species varied from 80-220 mm with minimum size of first maturity was recorded at 110 mm. The species was categorized into two group’s viz., group I (<110 mm) and group II (110 mm) for the convenience of interpretation. The ‘b’ value was encountered as 3.1634 and 2.9978 from the group I and group II specimen respectively. The fish exhibited isometric growth. Relative condition (Kn) factor was varied from 1.029 to 1.217. There were significance differences (P<0.05) in Kn value of Channa punctata during the period of study. Gonado-somatic index values (GSI) varied from 0.50 to 2.30 for males and 0.52 to 5.26 for females. |
