ABSTRACT:
This invention is a screening apparatus for retaining small marine animals in a growing container connected to closed-loop aquaculture system. The screening apparatus comprises (a) a first plate; (b) a second plate about the same size as the first plate and substantially parallel to and spaced from the first plate; (c) a conduit passing through a centrally-located aperture in the first plate, the end of the conduit being attached to a face of the second plate, the corresponding edges of said plates being about the same distance from the outer wall of the conduit; (d) a fluid permeable material extending between the edges of said plates and enclosing said conduit by being snugly fitted at least around the periphery of the first plate; (e) the conduit having apertures around its circumference; and (f) a pump means for transferring a fluid through the conduit. The screening device is particularly useful in a closed-loop aquaculture system which includes a biological filter means. The process for growing marine animals using the screening device is also disclosed.
