dc.description.abstractHemibagrus wyckii is one of vulnerable Bagridae species that inhabit the Kampar Kanan Rivers, Riau, Indonesia. A preliminary study on the reproduction of the H. wyckii has been conducted from April to August 2015 in order to determine the reproductive aspects of this fish. The number of fishes sampled was 45. The fish was captured by fishermen using fishing lines. Parameters measured were total length (cm), body weight (g), sex and reproductive condition of the fish, including gonadal maturity stages, fecundity, egg diameter, and spawning type. The eggs were preserved in Gilson solution and the diameter was measured. The fecundity was calculated using a gravimetric method. Results obtained shown that 36 males (TL 42.9 to 65.2 cm and BW 961-2,898 g) and 9 females (TL 56.4 to 79.2 and BW of 1,910 to 4,710 grams) were captured. Gonadal Somatic Index of the male ranged from 0.6 to 2.00% and that of the female was 0.88-3.97%. The fecundity range from 3,876-9,588 eggs and the egg diameter was range from 1.04-2.81 mm. Data obtained indicate that the type of the oocyte development of H.wyckii is asynchronies with partial spawning.en_US
