This study was designed to evaluate the trait performance using different dosage of
hormones ovaprim. Hormones ovaprim had been used to induce the final oocyte
maturation and spawning in fish. Hybrids between Clarias gariepinus and
Pangasianodon hypophthalmus were obtained by hormone injection of brood stock
and artificial injection. Three different dosages (0.3 ml/kg, 0.4 ml/kg and 0.5 ml/kg)
had been used and the concentration of the sperm of P. hypophthalmus is ranging
from (18.4× 10 5 -21.3× 10 5 /ml. In this study, for fertilization rate, hybrid
♀Pangasianodon hypophtalamus ×♂Clarias gariepinus (Pangapinus) is not significantly
difference and ranging from 42%-52% (p:0.057) . Hatching rate is significantly high
which is from 5.5%-13.9% (p:0.002). Survival rate is not significantly difference and
ranging from 22.22%-77.51% (p:0.079). Finally, abnormal rate is not significantly
difference and ranging from 33.33% – 83.01% (p:0.450).). Present result showed that
treatment 3 with 0.5 ml/kg ovaprim is preferable for the crossbreeding of
Pangasianodon hypophthalmus and Clarias gariepinus.
