Oxygenation assembly for aquaculture

Abstract

There is provided an oxygenation assembly submersible within a body of water. The oxygenation assembly includes a mass transfer vessel configured to receive water and promote dissolving of oxygen therewithin at least in part using pressure from the body of water. The vessel is elongate and may have a fixed diameter. The oxygenation assembly includes a bubble generator downstream of the vessel and which functions as a throttling device. The bubble generator is configured to dissipate pressure within the vessel in a manner that promotes breaking up of remaining undissolved gaseous bubbles. The oxygenation assembly may include an aeration system coupled to and in this example in line with the vessel. The aeration system disperses water of elevated dissolved oxygen content throughout a larger volume of water having a lower bulk dissolved oxygen concentration.
