Abstract

The present disclosure relates to a method of culturing a floating aquatic species, the method including introducing the aquatic species into a receptacle having (a) a culture medium, (b) at least one raceway configured to allow the culture medium to flow in a continuous loop, and (c) a sufficient quantity of the culture medium to flow in the continuous loop; cultivating the aquatic species to generate a floating mat on a top surface of the culture medium; generating a fluid current of sufficient force to propel the floating mat on the top surface of the culture medium; and varying a velocity of the fluid current in a controlled manner to maintain a relatively uniform distribution of the floating mat on the top surface of the culture medium.

Claims (42)

1. A method of culturing an aquatic species, the method comprising:

introducing the aquatic species into a receptacle comprising: (a) a culture medium, (b) at least one raceway configured to allow the culture medium to flow in a continuous loop, and (c) a sufficient quantity of the culture medium to flow in the continuous loop;

cultivating the aquatic species to generate a floating mat on a top surface of the culture medium;

generating a fluid current of sufficient force to propel the floating mat on the top surface of the culture medium; and

varying a velocity of the fluid current in a controlled manner to maintain a relatively uniform distribution of the floating mat on the top surface of the culture medium.

2. The method of claim 1 , wherein the fluid current is generated by a propulsion mechanism, and

wherein the propulsion mechanism is selected from a paddle wheel and a fluid pump.

3. The method of claim 1 , further comprising harvesting the aquatic species with a harvest system.

4. The method of claim 3 , wherein the harvest system comprises at least one of: a conveyer belt and a surface skimmer.

5. The method of claim 3 , wherein harvesting the aquatic species with the harvest system further comprises:

coupling the harvest system to a propulsion system, wherein: (a) the harvest system comprises a conveyer belt and a harvest channel wall, (b) the propulsion system comprises a paddle wheel, and (c) the harvest channel wall is coupled to the paddle wheel;

generating a channel between the paddle wheel and the conveyor belt, wherein the harvest channel wall is configured to extend from the paddle wheel in a manner such that the channel is generated between the paddle wheel and the conveyor belt; and

directing at least a portion of the floating mat to the conveyor belt through the channel.

6. The method of claim 1 , further comprising monitoring at least one of: (a) a uniformity of distribution of the floating mat across the top surface of the culture medium, (b) a thickness of the floating mat (c) a density of the floating mat, (d) a pH of the culture medium, (e) a concentration of carbon dioxide in the culture medium, and (f) a concentration of one or more nutrients in the culture medium.

7. The method of claim 6 , wherein the monitoring is performed by a sensor and the method further comprises:

collecting a data point about a monitored metric;

generating a sensor signal comprising the data point; and

transmitting the sensor signal.

8. The method of claim 7 , the method further comprising:

receiving the sensor signal at a control mechanism, wherein the control mechanism is operatively linked to the sensor and at least one a regulator, wherein the regulator comprises at least one of:

a propulsion mechanism, configured to generate a fluid current with a velocity;

a harvest system, configured to harvest the aquatic species;

a sprinkler system; and

an additive source;

determining, in response to the received sensor signal, if a threshold level of a monitored metric is reached;

generating a regulation signal in response to the threshold level of the monitored metric being reached; and

transmitting the regulation signal.

9. The method of claim 8 , the method further comprising:

receiving the regulation signal at the regulator; and

performing a regulatory function at the regulator in response to the regulation signal.

10. The method of claim 9 , wherein the regulator comprises the propulsion mechanism and the regulatory function comprises changing the velocity of the fluid current.

11. The method of claim 10 , wherein the velocity of the fluid current is regulated such that the floating mat on the top surface of the culture medium is propelled at a speed of at least 0.01 m/s.

12. The method of claim 10 , wherein the velocity of the fluid current is regulated such that the floating mat on the top surface of the culture medium is propelled at a speed of between 0.01 m/s and 0.10 m/s.

13. The method of claim 9 , wherein the regulator comprises the harvesting system and the regulatory function comprises activating the harvest system.

14. The method of claim 9 , wherein:

the regulator comprises the additive source, configured to be in fluid communication with at least one of: (a) the receptacle and (b) the sprinkler system, and comprising at least one of: (a) a nutrient tank and (b) a source of an alkaline salt; and

the regulatory function comprises dispensing at least one of: nitrogen, phosphorous, potassium, carbon dioxide, a micronutrient, and an alkaline salt.

15. The method of claim 1 , further comprising adding a wind barrier, wherein the wind barrier is configured to reduce a wind force applied to the floating mat on the top surface of the culture medium by an atmospheric wind.

16. The method of claim 15 , wherein the wind barrier is further configured for at least one of: (a) mounting to a peripheral wall of the receptacle and (b) floating in the receptacle.

17. The method of claim 16 , wherein the wind barrier comprises at least one of: (a) a mesh curtain having a height of about 50 cm to 100 cm and (b) a mesh curtain comprising knitted plastic.

18. The method of claim 17 , wherein the knitted plastic comprises about 50% porosity openings.

19. The method of claim 1 , further comprising applying a mist across the width of the receptacle.
