Effect of PMSG+AD hormone variation on the gonadal maturation of Pedih fish (Tor douronensis)

Abstract

Abstract Pedih (Tor douronensis) is a freshwater fish that live in mountainous areas and swift rivers in the interior of Aceh. The aimed of this research was to analyze the dosage of PMSG+AD hormone orally for the gonadal maturation of pedih (Tor dauronensis). This research was conducted at technical implementation unit of fish breeding center Lukup Badak, Pegasing district, Aceh Tengah on Febuary to March 2018. The method used was Completely Randomized Design (CRD) with 4 level of treatment and three replications: 0 ml/kg feed, 0.3 ml/kg feed, 0.5 ml/kg feed and 0.7 ml/kg feed. The result of ANOVA test showed that different dosage of PMSG+AD hormone orally showed significant effect on the weight of broodstock, relative weight, gonad maturations index, eggs diameter, and relative eggs diameter. The result of Duncan test showed that the best dosage was found 0.7 ml/kg feed, but this treatment was not significantly different with the dosage of 0.5 ml/kg feed.
