Abstract
Emperor Tetra fish is an imported ornamental freshwater fish with a unique phenotype, popular in the domestic and international ornamental fish market. The study was conducted to determine the potential influence of culturing conditions and foods on the reproductive maturity of Emperor Tetra fish. The study included two experiments: (1) Culturing the fish with 3 different conditions: normal glass tanks, aquariums, driftwood tanks, (2) Culturing the fish with 3 different foods: Artemia, bloodworms, industrial food. The results showed that males achieved the highest maturity rate (over 78%) in the aquarium treatment, while females achieved the highest maturity rate (over 87%) in the glass tank treatment. The most suitable diets for Emperor Tetra fish were Artemia and bloodworms, resulting in a maturity rate ranging from 76% to 85%. In addition, suitable culturing conditions and diets could improve the maturation rate, fertility and enhance the production efficiency.
