Technical Abstract: A small single-axle trailer was designed and built to hold three 50-gallon liquid oxygen dewars. The unit is small enough to be moved around a commercial channel catfish farm with a pickup truck. It was routinely used to provide supplemental oxygen to remote on-farm locations where channel catfish were being held in a sock at high density prior to sale. The total cost of the complete sock-saver was $8400. It is simple to operate, durable and virtually maintenance-free. Since it does not require any electrical or mechanical power source, it can be safely set up anywhere. The unit increased dissolved oxygen in a sock by as much as 0.9 mg/L, reducing mortality and potentially improving processed product quality.
