Combination of Ovaprim and Oxytocin Hormones for Growth and Survival of Betok Fish (Anabas testudineus)

Abstract

Analyzing the administration of a combined dose of the hormone ovaprim and oxytocin on ovulation and spawning of betok fish (A. testudineus) and analyzing the concentration of the hormone estradiol-17β in the blood before injection of the hormone ovaprim and oxytocin and after spawning. The method in this study used a completely randomized design consisting of five treatments and three replications consisting of 100% ovaprim + 0% oxytocin, 75% ovaprim + 25% oxytocin, 50% ovaprim + 50% oxytocin, 25% ovaprim + 75% oxytocin and 0% ovaprim + 100% oxytocin with a hormone injection dose of 0.5 mL/kg weight of broodstock betok fish. The results of this research are. The results of the research are that giving the hormone 50% ovaprim + 50% oxytocin is a treatment that can accelerate the growth of betok fish larvae, namely 3.84 cm and then the hormone 50% ovaprim + 50% oxytocin is a treatment that can increase the survival rate of betook fish by 97.45%.
