ABSTRACT:
This invention pertains to a fish pond system for use as a fish pond amusement park. The fish pond system includes a fish pond having at least one fish container in a deeper, typically a central region, and a pond liner extending outwardly from the fish container, preferably inclined at a generally upward angle, preferably less than 10 degrees. The pond has a shallower zone having a depth of at least about 7 inches at the juncture of the central region and the shallower zone. The fish container has greater depth than the shallower zone such that fish congregate in the fish container. The fish pond system preferably includes a water recirculation system receiving water from the bottom of the fish container, passing the water through a settling container, typically a settling pond, and returning the water to the fish pond. Fish waste solids settle to the bottom of the settling pond, and are removed to a decomposition pond within the fish pond system, where the fish wastes are biologically decomposed by plants. The fish pond system preferably includes an aerator controlling oxygen in the water, and water plants removing nitrates and phosphates from the water. An optional biofilter supports bacteria that convert ammonia in the water to nitrite and then to nitrate. Thus the fish pond system generates substantially no waste for off-site transport for disposal or treatment away from the area of the fish pond system.
