Method and system for aquaculture production
View Patent ↗A system and method provide an intensive aquaculture system for producing caviar or other goods. The system has a photosynthetic subsystem to consume waste from a production species, a food production subsystem to consume the photosynthetic species and be eaten by the production species. Optionally, the food production species may be pelletized or otherwise refined before being consumed by the production species. While each subsystem may have its own water chemistry, gas scrubbers may be used to control gas levels among the subsystems. In one implementation, an enclosure is used with a sensor to measure the gas above the water in the photosynthetic species. Water and species may be transferred among the subsystems as desired. Multiple aquaculture systems may be used in combination to provide age-specific systems operating in conjunction with one another and distribute risk of disease or failure across multiple systems.
1. A method of aquaculture, comprising:
growing a photosynthetic first species in a first tank, water in the first tank having a first water chemistry;
providing the first species to a second species in a second tank that eats the first species, water in the second tank having a second water chemistry different from the first water chemistry;
providing the second species to a fish in a third tank; and
wherein the second water chemistry has less nitrogenous waste and carbon dioxide than the first water chemistry.
2. The method of claim 1 , wherein water in the third tank has a third water chemistry, different from both the first water chemistry and the second water chemistry.
3. The method of claim 1 , wherein the first species is not provided to the fish.
4. The method of claim 1 , further comprising the act of circulating water from the first tank to a filter dedicated to the first tank and back into the first tank.
5. The method of claim 4 , further comprising the act of circulating water from the second tank to a filter dedicated to the second tank and back into the second tank.
6. The method of claim 5 , further comprising the act of circulating water from the third tank to a filter dedicated to the third tank and back into the third tank.
7. The method of claim 1 , further comprising the act of providing a water storage device coupled to the first tank, the second tank and the third tank.
8. The method of claim 1 , further comprising the act of activating a water transfer device to enable transfer of water between the third tank and the first tank.
9. The method of claim 8 , wherein the act of activating is triggered by a nitrogen compound level of the water in the third tank.
10. The method of claim 8 , wherein the act of activating is triggered by a nitrogen compound level of the water in the first tank.
11. The method of claim 8 , wherein the act of activating is triggered by a water quantity in the first tank.
12. The method of claim 1 , wherein the first species is a non-floating plant.
13. The method of claim 1 , wherein the fish is a sturgeon.
14. The method of claim 1 , wherein a ratio of volumes of water in the third tank and in the first tank is 2:1.
15. A method of aquaculture, comprising:
growing a photosynthetic first species in a first tank, water in the first tank having a first water chemistry;
providing the first species to a second species in a second tank that eats the first species, water in the second tank having a second water chemistry different from the first water chemistry;
providing the second species to a fish in a third tank; and
wherein the first species is phytoplankton and the second species is zooplankton.
16. The method of claim 15 , wherein water in the third tank has a third water chemistry, different from both the first water chemistry and the second water chemistry.
17. The method of claim 15 , wherein the first species is not provided to the fish.
18. A method of aquaculture, comprising:
growing a photosynthetic first species in a first tank, water in the first tank having a first water chemistry;
providing the first species to a second species in a second tank that eats the first species, water in the second tank having a second water chemistry different from the first water chemistry;
providing the second species to a fish in a third tank; and
stripping carbon dioxide from the water in the third tank and supplying the carbon dioxide to water in the first tank.
19. The method of claim 18 , wherein water in the third tank has a third water chemistry, different from both the first water chemistry and the second water chemistry.
20. The method of claim 18 , wherein the first species is not provided to the fish.
