Abstract
Abstract A method and apparatus for raising plant and animal life in a marine environment. Fish, snails, other animal life as well as plants are raised in a raceway which is embedded in a bed of porous material with one end lower than the other. Temperature controlled water flows through the raceway with the water movement helping to maintain the water clean of waste products and nitrates that normally accumulate in circulating water tanks. If necessary, geothermal water conducted through tubes proximate to the raceway can be used to maintain the flowing water in the raceway at an ideal temperature for promoting the rapid growth of the fish, plant and animal life. When the fish or other animals being cultivated are ready to be harvested, a catch box designed for use in the raceway is pulled along the raceway. The catch box, with the captured cultivated animals is then removed from the raceway.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
205 words
Apparatus for raising plant and animal life in a marine environment comprising an elongate raceway through which water is flowed, said raceway including a bottom and side walls extending upwardly from opposite sides of said bottom, an inlet end wall and an outlet end wall; a source of heated water; means for supplying heated water from said source to the inlet end of said raceway; a partition extending across the raceway, said partition providing a solid barrier across the raceway at an upper portion thereof and being perforated at a lower portion thereof; a discharge pipe extending upwardly in the raceway to a height just below the uppermost edges of the side walls and partition; and a catch box in the raceway, said catch box including a bottom and a pair of side walls adapted to fit snugly within the raceway bottom and side walls, a downstream panel forming a back wall interconnecting the bottom and side walls of the catch box, said downstream panel having a solid lower portion and a perforated upper portion to allow water flow therethrough and to restrict movement of fish therethrough, and a removable panel interconnecting the upstream ends of the bottom and side walls of the catch box.
Claim 2
Dependent Claim
205 words
Apparatus for raising plant and animal life in a marine environment comprising an elongate raceway through which water is flowed, said raceway including a bottom and side walls extending upwardly from opposite sides of said bottom, an inlet end wall and an outlet end wall; a source of heated water; means for supplying heated water from said source to the inlet end of said raceway; a partition extending across the raceway, said partition providing a solid barrier across the raceway at an upper portion thereof and being perforated at a lower portion thereof; a discharge pipe extending upwardly in the raceway to a height just below the uppermost edges of the side walls and partition; and a catch box in the raceway, said catch box including a bottom and a pair of side walls adapted to fit snugly within the raceway bottom and side walls, a downstream panel forming a back wall interconnecting the bottom and side walls of the catch box, said downstream panel having a solid lower portion and a perforated upper portion to allow water flow therethrough and to restrict movement of fish therethrough, and a removable panel interconnecting the upstream ends of the bottom and side walls of the catch box.
Claim 3
Dependent Claim
24 words
Apparatus as in claim 1, wherein the catch box further includes handle means thereon, whereby said catch box may be moved along the raceway.
Claim 4
Dependent Claim
40 words
Apparatus as in claim 2, wherein the heated water is provided by a geothermally heated source; and the inlet end is slightly higher than the outlet end of the raceway to thereby provide gravity flow of water along the raceway.
Claim 5
Dependent Claim
16 words
Apparatus as in claim 3, further including means to heat the water moving through the raceway.
Claim 6
Dependent Claim
45 words
Apparatus as in claim 4, wherein the means for heating water moving through the raceway includes conduit means connected to the source of geothermally heated water, said conduit means being arranged so that hot water passed therethrough conductively heats the water moving through the raceway.
Claim 7
Dependent Claim
28 words
Apparatus as in claim 5, further including a porous bed of material beneath the raceway, and wherein the conduit means is embedded in said porous bed of material.
Claim 8
Independent Claim
135 words
A method of handling and growing animal life in water comprising providing a restricted area in a flow stream of heated water in which animal life is placed and can freely move; using the flow stream of water to wash away animal waste from said restricted area; and capturing the animal life by moving a catch box having a bottom, sides and a downstream panel interconnecting the bottom and sides and extending fully across the flow stream, said panel having perforations therein to permit water flow therethrough and to restrict passage of larger animal life therethrough while allowing passage of smaller animal life therethrough, along the length of the raceway from the discharge end to the inlet end, closing the upstream end of the catch box and raising the catch box from the flow stream.
Claim 9
Independent Claim
135 words
A method of handling and growing animal life in water comprising providing a restricted area in a flow stream of heated water in which animal life is placed and can freely move; using the flow stream of water to wash away animal waste from said restricted area; and capturing the animal life by moving a catch box having a bottom, sides and a downstream panel interconnecting the bottom and sides and extending fully across the flow stream, said panel having perforations therein to permit water flow therethrough and to restrict passage of larger animal life therethrough while allowing passage of smaller animal life therethrough, along the length of the raceway from the discharge end to the inlet end, closing the upstream end of the catch box and raising the catch box from the flow stream.
Claim 10
Dependent Claim
134 words
Apparatus for raising plant and animal life in a marine environment comprising an elongate raceway having a bottom and interconnected side and inlet and outlet end walls projecting upwardly from the bottom; means for supplying water source to the inlet end of the raceway; means for removing water from an upper portion of the raceway adjacent to the outlet end thereof; and a catch box in the raceway, said catch box including a bottom and a pair of side walls adapted to respectively fit snugly against the bottom of the raceway and the side walls thereof, a perforated downstream panel interconnecting the bottom and side walls of the catch box at a downstream end thereof, and a removable panel sealingly interconnecting the upstream ends of the bottom and side walls of the catch box.
Claim 11
