Abstract A self-recording linear gradient tank and procedures are described in which individual brook trout fingerlings unstressed by recent transfer, unaccustomed surroundings or the presence of an observer could move freely in 16 oxygen concentration gradients within the limits of 1 and 8.9 mg O2/l. They avoided oxygen concentrations below 4 mg/l most of the time and preferred 5 mg/l or higher more than half the time, which supports the field-derived belief that fish avoid oxygen concentrations below 5 mg/l in the natural environment if they can.
