Abstract
Abstract A platform is maintained at a fixed or controlled variable distance below the surface of waters which do not naturally have a substrate suitable for production of marine food; e.g. beyond the continental shelf. Nutrients (e.g. waste biological products) are supplied to the platform, preferably at a controlled rate. The depth of the platform is such that solar energy or other illumination causes the nutrients to reinforce the natural ecosystem, thereby increasing the production of fish which may be harvested as human food.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
96 words
A system for production of marine food comprising an open platform containing materials to support flora and fauna, first means located totally below the surface of the water for maintaining said platform submerged at a selected depth in an open body of water within the euphotic zone so that said platform is not subjected to wave action on the surface, and second means for supplying nutrients to said platform over an extended period of time, whereby the occurrence of phytoplankton and plankton in the vicinity of said platform is increased and bloom of zooplankton is increased.
Claim 2
Independent Claim
96 words
A system for production of marine food comprising an open platform containing materials to support flora and fauna, first means located totally below the surface of the water for maintaining said platform submerged at a selected depth in an open body of water within the euphotic zone so that said platform is not subjected to wave action on the surface, and second means for supplying nutrients to said platform over an extended period of time, whereby the occurrence of phytoplankton and plankton in the vicinity of said platform is increased and bloom of zooplankton is increased.
Claim 3
Dependent Claim
26 words
A system according to claim 1 in which said first means is a tower supporting said platform extending from the bottom of said body of water.
Claim 4
Dependent Claim
47 words
A system according to claim 1 in which said first means comprises buoyancy tank attached to said platform, a source of compressed gas, first valve means for admitting said compressed gas to said tank and second valve means controlling water admission to and discharge from said tank.
Claim 5
Dependent Claim
69 words
A system according to claim 3 which further comprises third means responsive to a signal from a remote source to control said second means and said first and second valve means, fourth means to transmit to said source data as to at least some of the conditions existing at said platform, said conditions comprising weather, water temperature, water turbulence, extent of marine life and the location of said platform.
Claim 6
Dependent Claim
13 words
A system according to claim 1 in which said materials comprise benthic materials.
Claim 7
Dependent Claim
14 words
A system according to claim 1 which further comprises hollow structures on said platform.
Claim 8
Dependent Claim
27 words
A system according to claim 1 which further comprises means for artificial illumination of the area above said platform and a power source for said last-named means.
Claim 9
Independent Claim
104 words
A method for increasing the production of fish and aquatic life in an area where water depth, lack of natural nutrients or the condition of the substrate inhibits natural production of plant life and fauna comprising providing an open platform habitat suitable for growth of plants and animals, locating said platform in an open body of water at a pre-selected depth in the euphotic zone of said water in said area, said platform being totally below the surface and not subject to disturbance by wave action on the surface, and providing controlled quantities of nutrients to said platform over a prolonged period of time.
Claim 10
Independent Claim
104 words
A method for increasing the production of fish and aquatic life in an area where water depth, lack of natural nutrients or the condition of the substrate inhibits natural production of plant life and fauna comprising providing an open platform habitat suitable for growth of plants and animals, locating said platform in an open body of water at a pre-selected depth in the euphotic zone of said water in said area, said platform being totally below the surface and not subject to disturbance by wave action on the surface, and providing controlled quantities of nutrients to said platform over a prolonged period of time.
Claim 11
Dependent Claim
16 words
A method according to claim 8 in which said platform is anchored beyond the continental shelf.
Claim 12
Dependent Claim
56 words
A method according to claim 8 in which said platform is supported by buoyancy means comprising a tank containing water and compressed gas and in which said method comprises controlling by remote radio control the admission to and discharge from said tank of compressed gas and water and the rate of providing nutrients to said platform.
Claim 13
Dependent Claim
16 words
A method according to claim 8 which further comprises artifically illuminating the water above said platform.
