This research aims to analyze the optimum used of low temperatures (12 ºC, 16 ºC, 20 ºC and temperature control (24 ºC)) at the beginning of transport on the survival rates of goldfish juvenile (Carassius auratus L.) size of ± 3 cm with a density of 20 goldfish /2 liters of water in transportation with closed systems for 8, 10 and 12 hours where the goldfish is transported at 21:00 PM. This research used an experimental method Factorial Randomized Group Design which consists of two factors that is, a four-level temperature factor and a three-level time factor and repeated three times. The parameters observed were the survival rate, water quality, duration of the process anesthesia, duration of the process recovery after transportation and pisciculture after transportation. The results showed the effect of low temperature and time of transportation had a significant effect on the survival rate of goldfish (Carassius auratus L.) in transportation with closed systems. The optimum temperature and duration of time for transportation of goldfish (Carassius auratus L.) was a temperature of 16 °C and 12 hours of transportation time, 98.33% survival was obtained. This species of fish comes from regions of Japan, South Korea, South east China, Malaysia, Thailand, Vietnam, Indonesia and Philippines. Currently, this fish is found worldwide as a breeding copy.
