Aquaculture system

An apparatus for supplying oxygenated water in an aquaculture system for farming aquatic organisms, the apparatus comprising:

• a water inlet for supplying water into the apparatus;
• an oxygen inlet for supplying oxygen into the water within the apparatus to create a water and oxygen mixture, the oxygen inlet being in fluid communication with, and downstream of, the water inlet;
• a diffusion chamber;
• wherein the diffusion chamber is in fluid communication with, and downstream of, the water inlet;
• wherein the diffusion chamber is in fluid communication with, and downstream of, the oxygen inlet;
• wherein the diffusion chamber is arranged such that the oxygen is supplied through the oxygen inlet into the diffusion chamber to create the water and oxygen mixture;
• a mixing chamber;
• wherein the mixing chamber is in fluid communication with, and downstream of, the diffusion chamber;
• wherein the mixing chamber is arranged to receive the water and oxygen mixture from the diffusion chamber;
• and
• wherein the mixing chamber comprises one or more obstacles and/or a tortuous path to induce turbulence into the water and oxygen mixture flowing therethrough and break-up the oxygen into a plurality of oxygen bubbles;
• wherein the apparatus further comprises:
• a venturi;
• wherein the venturi is in fluid communication with, and downstream of, the mixing chamber;
• wherein the venturi is arranged to dissolve the oxygen into the water when the water and oxygen mixture passes through the venturi and such that the oxygen and water mixture passing through the venturi is exposed to a substantially null magnetic field;
• and
• wherein the apparatus is arranged such that the water and oxygen mixture that is supplied to the venturi contains substantially no colloidal minerals;
• wherein the apparatus further comprises:
• an outlet for the oxygenated water in fluid communication with, and downstream of, the venturi, for supplying the oxygenated water for use in an aquaculture system;
• and
• wherein the apparatus is arranged to produce oxygenated water with a concentration of dissolved oxygen of between 62 mg/l and 125 mg/l.

An aquaculture system for farming aquatic organisms comprising:

• an enclosure for oxygenated water in which aquatic organisms are to be farmed, wherein the enclosure comprises an inlet for feeding oxygenated water into the enclosure;
• an apparatus for supplying oxygenated water into the enclosure, the apparatus comprising:
• a water inlet for supplying water into the apparatus;
• an oxygen inlet for supplying oxygen into the water within the apparatus to create a water and oxygen mixture, the oxygen inlet being in fluid communication with, and downstream of, the water inlet;
• a mixing chamber;
• wherein the mixing chamber is in fluid communication with, and downstream of, the water inlet and the oxygen inlet;
• wherein the mixing chamber is arranged to receive the water and oxygen mixture from the water inlet and the oxygen inlet;
• and
• wherein the mixing chamber comprises one or more obstacles and/or a tortuous path to induce turbulence into the water and oxygen mixture flowing therethrough and break-up the oxygen into a plurality of oxygen bubbles;
• wherein the aquaculture system further comprises:
• a venturi;
• wherein the venturi is in fluid communication with, and downstream of, the mixing chamber;
• wherein the venturi is arranged to dissolve the oxygen into the water when the water and oxygen mixture passes through the venturi and such that the oxygen and water mixture passing through the venturi is exposed to a substantially null magnetic field;
• and
• wherein the apparatus is arranged such that the water and oxygen mixture that is supplied to the venturi contains substantially no colloidal minerals;
• wherein the aquaculture system further comprises:
• an outlet for the oxygenated water in fluid communication with, and downstream of, the venturi;
• wherein the outlet of the apparatus is in fluid communication with the inlet of the enclosure;
• wherein the apparatus is arranged to produce oxygenated water with a concentration of dissolved oxygen of between 62 mg/l and 125 mg/l;
• and
• wherein at least part of the water inlet, at least part of the oxygen inlet, at least part of the venturi, and at least part of the outlet are integrally formed as a unitary piece of material.
