Abstract

A plurality of porous enclosures are provided to segregate groups of fish for testing and commercial purposes. The enclosure mesh is small enough to retain the fish, yet large enough to permit water flow. The enclosures are arranged circle fashion about a central shaft imbedded in the pond floor, and held in place between two concentric rings by a shaped support frame engaged at either end by the rings. A rotational sleeve sits about the shaft and is joined to the rings by spoke-like members, and flotation elements are provided for the ring-sleeve structure. The assembly is regularly rotated around the shaft, so that the fish within the different enclosures are kept segregated yet exposed to the same environment.

Claims

1. Apparatus for housing segregated gRoups of fish in a fish pond, comprising a plurality of water permeable fish enclosures circumscribing a central member, said central member immoveably imbedded in the floor of said fish pond and extending upwardly therefrom, means rotatable about said central member having means for detachably engaging said enclosures, and floatation means associated with said rotatable means.

2. Apparatus for housing segregated groups of fish in a fish pond, comprising a plurality of water permeable fish enclosures circumscribing a central vertical shaft, said shaft immoveably imbedded in the floor of said fish pond and extending upwardly therefrom, a sleeve girding a portion of said shaft and rotatable thereabout, a laterally spaced pair of rigid concentric rings held in fixed relationship to said sleeve and circumscribing said shaft, a frame associated with each of said enclosures, said frames positioned between said concentric rings and detachably engaged thereto, means associated with each of said frames for holding said associated enclosures, and floatation means associated with said concentric ring assembly.

3. The apparatus described in claim 2, wherein each of said concentric rings is comprised of a flat base having an upward tending flange with a plurality of slots in the upper portion of said flange, and wherein arms extend from each of said frames adapted for positioning within said slots.

4. A structure for holding a plurality of fish enclosures in a fish pond, comprising a vertical central shaft immoveably imbedded in the floor of said fish pond and extending upwardly therefrom, a sleeve girding a portion of said shaft and rotatable thereabout, a spoked wheel having an inner rim and an outer rim, said spokes converging upon and joined to said sleeve, said inner and outer rims having support means for holding a plurality of water permeable fish enclosures between said rims and said supports and floatation means associated with said wheel.
