(Bleeker, 1854) by Using Synthetic and Non-synthetic Hormones]]>AzuadiN.M. SirajS.S. DaudS.K. ChristianusA. HarminS.A. SunganS. BritinR. 4201384Tor tambroides is an important and highly valued freshwater fish. In
Malaysia, wild populations of this species has undergone declines in range and
abundance due to degradation of their natural habitat. Due to economic important
and concerns about their conservation, a culture artificial propagation programme
was established to produced seed-stock for aquaculture and conservation purposes.
The effectiveness of selected synthetic and non-synthetic commercial hormones
was tested on filial 1 generation (F1) of Tor tambroides (Bleeker
1854) females in captivity. A total of 144 matured females were given intramuscular
implantation of slow release hormone, Ovaplant (38.6-53.6 μg kg-1
b.wt.), for 5-6 weeks prior to induction. Selected commercial hormones were
compared for the induction. The effect of these hormones on breeding performance
and larval quality of F1 Tor tambroides were evaluated. The
results showed that Ovatide (0.5 mL kg-1 BW) was the most reliable
hormone in inducing ovulation of F1T. tambroides females
overshadowed the other tested hormones. Ovaprim (0.5 mL kg-1 b.wt.)
was the next best tested hormone followed by a synthetic analogue of salmon
gonadotropin releasing hormone (sGnRHa/OvaRH) (10 μg kg-1 b.wt.).
No ovulation occurred in the groups treated with Luteinizing Hormone Releasing
Hormone Analogue (LHRHa) (10 μg kg-1 b.wt.), Human Chorionic
Gonadotropin (HCG) (1000 μg kg-1 b.wt.) and Carp Pituitary Extract
(CPE) (10 mg kg-1 b.wt.). Ovatide was further chosen to test its
effectiveness at various dosage levels in inducing ovulation of T. tambroides.
Thus, concentration of 0.5 mL kg-1 b.wt. of Ovatide was found to
be the optimum dosage for inducing ovulation of F1T. tambroides
in captivity.]]>Azuadi, N.M., S.S. Siraj, S.K. Daud, A. Christianus, S.A. Harmin, S. Sungan and R.
