Aquaculture-feeding / oxygen-dissolution assembly for ocean applications and method thereof

A method of providing aquaculture feed and oxygenated water to a plurality of sea cages, the method comprising:

• dissolving oxygen into water via an oxygen dissolution system so as to output water of elevated dissolved oxygen;
• splitting the water of elevated dissolved oxygen into a plurality of distribution lines whose outlets are in fluid communication with respective said sea cages;
• injecting feed into each said distribution line;
• and
• adjusting flow through the distribution lines via water flow balancing valves, including adjusting a first water flow balancing valve of said water flow balancing valves associated with a sea cage of said plurality of sea cages that is closer to be more closed compared to a second water flow balancing valve of said water flow balancing valves associated with a sea cage of said plurality of sea cages that is more distant, to promote a consistent backpressure across multiple said outlets within a predetermined threshold.

An aquaculture assembly comprising:

• a pump for outputting water of a first concentration of dissolved oxygen;
• an oxygen dissolution system operatively connected to the pump so as to receive said water of the first concentration of dissolved oxygen, with the oxygen dissolution system outputting water of a second concentration of dissolved oxygen higher than that of the first concentration of dissolved oxygen;
• a manifold operatively connected to the oxygen dissolution system so as to receive said water of the second concentration of dissolved oxygen;
• a plurality of spaced-apart sea cages;
• a plurality of valves in fluid communication with respective outlets of the manifold, wherein a first said valve of said plurality of valves associated with a closer sea cage of said plurality of spaced-apart sea cages that is closer, is more closed compared to a second said valve of said plurality of valves associated with a more distant sea cage of said plurality of spaced-apart sea cages that is more distant, to promote a consistent backpressure across multiple said outlets within a predetermined threshold;
• and
• a plurality of feed injection conduits operatively connected to respective said valves.
