THE EFFECT OF FEED VARIATION ON THE REPRODUCTIVE EFFICIENCY OF GUPPY FISH (Poecilia reticulata)

Abstract

The purpose of this study is to analyze the impact of varying types of feed on the reproductive performance of guppy fish. The method used is an experimental method with a Completely Randomized Design (CRD) consisting of 4 treatments (P0: Pellet, P1: Bloodworms, P2: Mosquito larvae, P3: Water fleas) and 3 replications. The parameters tested include gonadal maturation, larval count, larval sex ratio, number of breeding adults, gestation period, survival rate, and water quality. The data obtained were tested for normality, and non-normal data were analyzed using the Kruskal-Wallis test. Normal data were analyzed using ANOVA at a 5% significance level, followed by Duncan's test at a 5% significance level. The results showed that varying feed types had no significant effect (p > 0.05) on the gonadal maturation parameter (ranging from TKG 3 to 4), larval sex ratio (ranging from 29.6% to 60.4%), and the number of breeding adults (ranging from 66% to 100%), as well as the gestation period (ranging from 12 to 17 days). However, the different feed types had a significant effect (p < 0.05) on the number of larvae (ranging from 8 to 22) and survival rate (ranging from 43.6% to 90.6%). It can be concluded that bloodworms and mosquito larvae provide the best results for the number of larvae and survival rate parameters.
