Abstract
This research was conducted from December 2011 to May 2012 in Hatchery
and Breeding Laboratory, Faculty of Fisheries and Marine Sciences, University of
Riau. The objective of the research was to know the success fullness of hybridization
between sheatfish (Ompok rhadinurus) and Patin catfish (Pangasius hypopthalmus).
The sheatfish broodstock were obtained from the Laboratory Fish Hatchery and
Breeding Faculty of Fisheries and Marine Sciences, University of Riau, while Patin
catfish derived from rearing fish farmers in ponds Sungai Pinang Kampar Regency.
Incubation containers used were 30x30x30cm3 aquarium and one fiberglass tank size
300x60x40cm3. Both broodstock were induced with 0,5 ml/body weight ovaprim to
fertilize the egg.
The results showed that the hybridization between the sheatfish and patin
catfish have been successfully carried out and obtain fertilization rate of 76.20% and
81.92%, the hatching rate of 65.37% and 65.48%, survival rate after 4 days of
56,85% and 69,33%. Where as for 7 days survival rate was 30,20% and 34,05 %. The
best respectively heterosis values was obtained of 26,43%. And the lowet value of
heterosis was 3,21 %. Survival rate was 25,78% (4 days) and 24,39% (7 days). Water
quality were parameter temperature 29-300c, pH from 5-6 and dissolve oxygen 1,8-
3ppm.
