PURPOSE: A water temperature control system of a water tank type culture farm is provided to supply a raw water of a predetermined temperature to the culture farm by controlling the flow amount of the raw water corresponding to a temperature change of the raw water. CONSTITUTION: A temperature value within a normal range of a raw water is set in a raw water supply source in a first step. The temperature of the raw water is measured in a second step. It is determined whether the temperature of the raw water measured in the second step is in the normal range or not in a third step. When the temperature of the raw water is in the normal range in the third step, the routine comes to feedback to the second step in a fourth step. When the temperature of the raw water is higher than the highest value of the normal range, the flow amount of the raw water is increased and the routine comes to feedback to the second step in a fifth step. When the temperature of the raw water is lower than the lowest value of the normal range, the flow amount of the raw water is decreased and the routine comes to feedback to the second step in a sixth step.
