Abstract
Embodiments disclosed herein disclose a fish brooding and filtration system. The system includes a brooding tank configured to contain water and fish for breeding. The brooding tank is in fluid communication a filtration tank, which is configured to extract nitrites from the water circulating through the system. A pump circulates the water through at least one conduit and an injector that receives a flow of water generated by the pump and draws air into the injector. The injector is further operable to inject a mixture of the drawn air and the water into the brooding tank.
Claims16
A fish brooding and filtration system, comprising:
- a brooding tank configured to contain water and fish for breeding;
- a filtration tank in fluid communication with the brooding tank, the filtration tank configured to extract nitrites from the water circulating through the system;
- a support structure supporting the filtration tank above the brooding tank;
- and
- a pump configured to circulate the water through at least one conduit and an injector, the injector operable to receive a flow of the water generated by the pump and to draw air into the injector, the injector further operable to inject a mixture of the drawn air and the water into the brooding tank.
A method for brooding fish, comprising:
- introducing stock fish into water in a brooding tank;
- circulating the water through at least three stages of filtration of a filtration tank to filter the water and using bacteria to convert harmful nitrites in the water into beneficial nitrates;
- and
- drawing air into an injector using a flow of the water through the injector;
- and
- injecting the air and water mixture into the water in the brooding tank for oxygenation.
A fish brooding and biofiltration system, comprising:
- a brooding tank containing water and fish for breeding;
- a biofiltration tank in fluid communication with the brooding tank, the biofiltration tank having at least three filtration stages and at least one stage extracting nitrites from the water circulating through the system;
- a pump circulating the water through at least one conduit and an injector and a tee fitting, the injector receiving a flow of the water generated by the pump and the flow of water drawing air into the injector, the injector injecting a mixture of the drawn air and the water into the brooding tank, the injector comprising:
- an injector body including an air inlet portion configured to receive the air;
- and
- a nozzle coupled to the injector body and coupled to the at least one conduit, the nozzle being configured to accelerate a flow of the water through the injector.
