Abstract
Abstract A floating enclosure for containing a closed volume of water for efficient fish raising. A closed membrane, forming the sides and bottom of the enclosure, is supported by a closed anchored chain of floats. Protective nets can be provided, inside and outside the enclosure, to enhance durability. Stiffener slats, insertable in pockets in the sides of the membrane, are provided. Catwalks across the enclosure may be included. The water quality within the enclosure is controlled by pumping in oxygenated and treated water. Gutters are provided at the periphery of the enclosure whereby displaced water exits therefrom. Nonreflective sectional tarps are provided to furnish surface protection to the enclosed body of water, and to utilize absorbed sunlight in heating the water.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
83 words
A floating fish enclosure for establishing a closed volume of water to provide a controlled environment conducive to fish raiSing comprising: a. a float system comprising floats; b. a water-impermeable flexible liner having sides and a bottom, connected at its periphery to said float system; and c. inclined gutters connected between the floats of said float system to allow easy passage of water outwardly from the interior of said liner, but substantially precluding entry of water into said liner from the outside thereof.
