Two major problems of sea pen farming are algae blooms and oxygen deficiency. Sea Pen Aeration systems can solve both problems at the same time. A compressor is used to blow air into a diffuser ring, which generates a upward flow within the pen that lifts cool, oxygen-rich water from the depths into the sea pen.
At the surface the water flows outwards, preventing algae and plankton (as well as planktonic stages of sea lice) from entering the sea pen. The rising bubbles also increase the oxygen saturation of the water, thus lowering the feed conversion ratio, as well as improving the overall health of the fish.
