GONAD REMATURATION ON Pangasionodon hypophthalmus FEMALE THROUGH INJECTION OF PREGNANT MARE SERUM GONADOTROPIN AND HUMAN CHORIONIC GONADOTROPIN
Abstract: The success of
spawning is influenced by internal and external factors. One of the factors
that affect the var iabi li ty of Pangasianodon hypophthalmus female
reproductive is the change of seasons that cause disrupted continuity of the
seed availability, especially in the dry season. In the present study,
combination of PMSG (pregnant mare serum gonadotropin) + HCG (hormone chorionic
gonadotropin) hormone injections was done to induce gonad development. The
treatments in this study were without hormone injections as control (A),
injection of PMSG 10 IU/kg + HCG 10 IU/kg (B), and injection of PMSG 20 IU/kg
HCG + 10 IU/kg (C). Injections were conducted at intervals of two weeks as many
as six times. The results showed that gonad maturation generally occurs 2-4
weeks after estradiol-17 peak. PMSG + HCG hormone injections
gave a significant effect on increasing the quantity and quality of eggs
production. The fecundity in the A, B, C treatments, were 233,700±220,676;
300,305±24,581 and 488,433±142,228; respectively. Number of larvae produced
from the A, B, C treatments, were 156,979±170,838; 229,997±18,081 and
362,713±101,850; respectively. Combination of PMSG 20 IU/kg + HCG 10 IU/kg
hormone injection gave the best result on fecundity and the number of larvae
production.
