Abstract
Goldfish is one of the most popular freshwater cultivated fish because it is one of the freshwater commodities that has economic value and is sold at a price that is affordable to all groups. Ginger is a natural ingredient that can stimulate fish growth. The purpose of this study was to determine the effect of adding ginger to feed and to determine a good dose of ginger for growth and survival rates of carp (Cyprinus carpio). This research was conducted by experimental method using completely randomized design (CRD) with 5 treatments and 3 replications. The treatments given were Treatment 1: 0 grams, without adding ginger / kg of feed (control), Treatment 2: 2.5 grams of ginger / kg of feed, Treatment 3: 5 grams of ginger rhizome / kg of feed, Treatment 4: 7.5 grams of ginger / kg of feed, Treatment 5: 10 grams of ginger / kg of feed. The results showed that the addition of ginger had no significant effect on absolute length growth, absolute weight growth, feed conversion ratio, and feed efficiency, but had a significant effect on the survival rate of goldfish (cyprinus corpio). And a good dose of ginger is in P2 treatment with a dose of 2.5 grams of ginger, because it has been able to show a good survival rate of 100%.
