Solid wall closed containment aquaculture system
This system for cultivating marine species employs a marine-based array of floating closed-containment tanks composed of panels made of waterproof fiberglass laminate materials and internal buoyant foam-based materials. The panels, connected by flanged struts, form the walls and bottom of the tanks, which are substantially cylindrical in overall shape. The tops of the tanks are open to the atmosphere but are protected from predators via a thick mesh top net. The system also employs a filtration system which utilizes centrifugal water flow and hydraulics to remove sludge and solid matter which is then filtered and transformed into a component for use in garden fertilizers. It also uses an electronic computerized system for monitoring and controlling the marine species rearing environment.
1. A solid wall closed-containment system for cultivating aquatic species, comprising floatation panels having a side portion that curves into a bottom portion, fitted between flanged struts and arranged to provide a continuous side wall contiguous with a continuous bottom to separate outside water and organisms from inside water and contained aquatic species, forming a tank that is substantially cylindrical in shape, with solid sides and bottom, made up of a plurality of side and bottom flotation panels having curved portions between side portions and bottom portions of each flotation panel, comprising at least one water pump mounted outside the tank and having a pump water outlet connected to a flared pipe that is sealed at an acute angle to a tank water inlet window in a side panel of the tank, to circulate water within the tank.
2. The solid wall closed-containment system of claim 1 , in which the side portion is curved vertically and forms an arc, such that a plurality of such side portions can be arranged to form a tank that is substantially cylindrical.
3. The solid wall closed containment system of claim 2 , in which:
a) the bottom portion is tapered toward a central drain abutment end and has a substantially conical portion, such that a plurality of such bottom portion can be arranged to form a tank having a bottom that is substantially conical and surrounds a drain aperture;
b) the floatation panels comprise floatation layers laminated with waterproof layers;
c) there is additionally a power system, an oxygenation system, a waste removal system, and a computerized husbandry monitoring system, with sensors and electronic controls for water temperature, flow, and quality;
d) there are at least two water pumps which have marine based water intakes, and which circulate water within the tank; and
e) there is a waste trap at a central bottom portion of the tank which collects solid matter and sludge for removal to a waste separation system.
4. The solid wall closed-containment system of claim 1 , in which the bottom portion is tapered toward a central drain abutment end and has a substantially shallow cone portion, such that a plurality of such bottom portions can be arranged to form a tank having a bottom that is substantially conical and surrounds a drain aperture.
5. The solid wall closed-containment system of claim 1 , in which the floatation panels comprise floatation layers laminated with waterproof layers.
6. The solid wall closed-containment system of claim 1 , in which the flanged struts comprise floatation layers laminated with waterproof layers.
7. The solid wall closed-containment system of claim 1 , comprising additionally a power system, an oxygenation system, and a waste removal system.
8. The solid wall closed-containment system of claim 1 , comprising additionally a computerized husbandry monitoring system, with sensors and electronic controls for water temperature, flow, and quality.
9. The solid wall closed-containment system of claim 1 , comprising at least two water pumps which have marine based water intakes, and which circulate water within the tank.
10. The solid wall closed-containment system of claim 1 , in which there is a waste trap at a central bottom portion of a tank formed by the flotation panels and flanged struts, to collect solid matter and sludge for removal to a waste separation system.
