Rekayasa rematurasi ikan patin siam Pangasianodon hypophthalmus dengan penyuntikan hormon PMSG dan HCG serta penambahan vitamin mix 300 mg/kg pada pakan

Abstract

The research was carried out from April to June, 2010 at Babakan Field LaboratoryPonds, Darmaga. The research aimed to increase the rematuration process rate on striped catfish Pangasianodon hypophthalmusthrough a combination of Pregnant Mare Serum Gonadotropin(PMSG)and Human Chorionic Gonadotropin (HCG) hormone injection with 5 and 2,5 IU; 10 and 5 IU;also 20 and 10 IU/kgof spawner body weight dosage combinedwith vitamin mixaddition to fish feed. Sixteen femalestriped catfish spawner were used, consisting of twelve PMSG-treatedspawner and 4 control spawner.This researchused one way single ANOVA with 4treatments and 3 replications. Statistic analysis of observed variables showed unsignificant differences among the three treatments in rematuration parameters. It was resulted that rematuration rate was increased in treatedspawners indicated by a 100% pregnancy. Spawners treated with 10 IU PMSG and 5 IU HCG/kg of spawner body weight along with 20 IU PMSG and 10 IU HCG/kg of spawner body weight dosage was able to reach maturity and spawned with the larval survival rate on the fourth day at 98,63% and 84,81% respectively, thus making 10 IU PMSG and 5 IU HCG/kg of spawner body weight as the best dosage.
