Abstract:
The studies on length-weight relationships (LWR) and condition factors (K) of Geso (Hemibagrus
wyckii, Bleeker, 1858, Bagridae) in Kampar Kanan River, Riau, Indonesia was conducted from February
to September 2015. A total of 99 specimens were collected from different sample stations using different
types of trapsnets and fishing pole. The pooled length–weight regression equation (Log W = -
6.1510+3.4536 TL, r = 0.936), and also the length-weight equations of males, females and juveniles (Log
W = -4.2274+2.6646 log TL (r=0.94), Log W = -3.4342 + 2.4225 log TL (r = 0.931) and Log W = -
2.1968 + 3.0405 log TL (r = 0.913) respectively), indicate positive correlation between length and weight
in H.wyckii. The mean values condition factor were ranged from 0.692±0.06 to 2.496±0.29, variations in
the condition factor were found to be influenced by the gonadal maturity and spawning season
