Controlling dissolved oxygen (DO) level in rearing tank is one of the most important for intermediate breeding of abalones with land based production facilities. Continuous DO measurement was conducted for two rearing tanks of 15.5 m3 seawater each and containing 19,000 abalone of 50 mm length and 60,000 abalone of 23 mm length in running seawater condition of 17.6 m3 per hour. Oxygen consumption of abalone was also examined. A model formula expressing oxygen distribution in rearing tank was made based on these data. There are diurnal changes in DO concentration in rearing tank, higher in afternoon and lower in midnight, and DO decreased to less than 80% of saturation couple of times, harmful level for good growth.
