A flow-through test system was designed to examine minimum dissolved oxygen (D.O.) requirements of marine animals. The system provides up to six treatment concentrations between 0.3 mg D.O./l and saturation. Sea water is degassed in a vacuum-evacuated packed column and the treatment concentrations are controlled electronically by time-proportional mixing of water from degassed and air-saturated seawater reservoirs. The system has proven capable of reliable continuous operation for test periods as long as 28 days.
