Abstract: The issue in goldfish egg production is the low hatching rate and the high adhesiveness of the eggs. The aim of this research was to optimization the temperature for incubating goldfish eggs that have been pre-immersion in a tannin solution (6 g/L). The research method used was an experimental method with 4 treatments: A (24 °C), B (26 °C), C (28 °C), D (30 °C). The results indicate that both temperature and tannin pre-treatment significantly affect the hatching rate and survival of goldfish. The best treatments were C and D, with fertilization rate of 94.33% and 97.00%, hatching rate were 90.33% and 94.33%, and survival rate were 83.67% and 88.33%, respectively. The least time for egg hatching, which was 3,120 minutes. It is suggested to farmers can use an incubation temperature of 28 °C to achieve good hatching rates and survival while saving production costs.
