DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

(5) As schematically represented in the accompanying Figures, the present invention is generally represented as 10 and is directed to the transferring of marine life within an aquaculture system, between a plurality of storage facilities 12, 13, 14, 15, etc. based, at least in part, on a stage of growth and/or development of the marine life while being processed. For purposes of clarity, the storage facilities 12-15, etc. each include structures such as, but not limited to, tanks maintaining containment water for the marine life which are adequate in number and dimension to process the marine life during a particular stage of growth and/or development. Also, as used herein the term aquaculture system is meant to include, but not be limited to, a recirculating aquaculture system (RAS).

(6) Further, in the different embodiments of FIGS. 1 and 2 each of the storage facilities 12-15, etc. may include a single tank or like containment structure or a plurality of such tanks or containment structures dependent, at least in part, on the quantity and/or size of the marine life being processed during respective growth stages. By way of non-limiting example, the plurality of storage facilities/tanks 12-15, etc. could include hatcheries, Parr tanks, smolt tanks, post smolt tanks, growing tanks, etc., each representative of the different stage of growth of the marine life. Also, the plurality of storage facilities 12-15, etc. could vary in number and be used for other developmental processing of marine life, rather than being associated with a specific growth stage as indicated.

(7) Therefore, as represented in both FIGS. 1 and 2, the transfer assembly and/or system 10 of the present invention includes the plurality of storage facilities 12-15, etc. each including containment water for marine life. In order to assure and facilitate proper growth and other processing of the marine life, the containment water within the plurality of storage facilities 12-15, etc. is maintained within a predetermined temperature range. Such predetermined and/or preferred temperature is in the range of about 14° C. As also indicated above, the plurality of storage facilities/tanks 12-15, etc. maintain the marine life at different stages of growth, wherein each developmental growth stage may comprise one or more storage facilities/tanks, based at least in part on the volume and size/age of marine life being processed over a given developmental period of time.

(8) Also, the plurality of storage facilities/tanks 12-15, etc. may be spaced and/or segregated from one another, such as being located in different buildings, shelters, housings, etc. As indicated, aquaculture systems of the type referred to herein may be extensive, again based at least in part on the volume of marine life being processed over a comparatively long developmental time period. As a result, while the aquaculture system may be located in the same location within a common geographical area, the one or more storage facilities/tanks 12-15, etc. associated with each developmental growth stage (hatchery, Parr tanks, smolt tanks, post smolt tanks, growing tanks, etc.) may be built, supported, disposed and located on, different independent ground levels 100, as represented in FIG. 1 or revised ground levels 101′, as represented in FIG. 2. Moreover, the different, independent ground levels 100 may be the same height or different heights due at least in part to the segregated disposition of the storage facility/tanks 12-15, etc. similarly, in the embodiment of FIG. 2 the ground levels 100′ may be the same height or different heights.

(9) As set forth herein, it is emphasized that the term “independent ground level”, as at 100, may refer to the natural or normal outer, exposed ground level, at a geographical location, on which the plurality of storage facilities 12-15, etc. are disposed. In contrast, the term “revised ground level” as at 100′, is meant to describe an operative ground level, at a given geographical location, on which the plurality of storage facilities 12-15 etc. are disposed and which is man-made and/or constructed to be at least a minimum height above the original normal or “independent ground level” 100. As such, the “revised ground level” 100′ is constructed, formed and operatively utilized in geographical areas where the proximate water table is relatively shallow and/or where the seasonal variance thereof serves to raise the water table to a shallow depth such as in, but not limited to, geographical regions such as Florida, as set forth above.

(10) As also represented in FIGS. 1 and 2, the assembly and/or system 10 of the present invention further comprises a transfer assembly generally indicated as 20 comprising a path of fluid flow 22, both of which are schematically represented, interconnecting successively communicating ones of the plurality of storage facilities/tanks 12-15, etc. in fluid communication with one another. As indicated, the path of fluid flow 22 may extend between two successively communicating storage facility/tanks, such as at 12 and 13. In the alternative, the path of fluid flow 22 may be accurately described herein as including one or more different fluid flow paths extending between different ones of the successively communicating storage facilities/tanks, such as between 12-13, 13-14, 14-15, etc. further, conduits, pipes or like structures may define the path of fluid flow 22 as being operatively associated with the transfer assembly 20.

(11) With further reference to FIGS. 1 and 2, at least a majority of a length of the path(s) of fluid flow 22 defining the transfer assembly 20 is disposed beneath the independent ground levels 100 and 100′, between the successively communicating storage assembly/tanks 12-13, 13-14, 14-15, etc. at a predetermined minimum depth 200. The predetermined minimum depth 200 is preferably in the range of 3 feet-4 feet and is sufficient to facilitate the maintenance of the path of fluid flow 22 within the predetermined temperature range of generally about 14° C. This is due to the fact that the path(s) of fluid flow 22 are not exposed to the sun or other above ground weather conditions.

(12) As indicated, the transfer assembly 20 and/or portions thereof which define the path(s) of fluid flow 22 may be in the form of one or more conduits, pipes, etc. dimensioned to transfer a predetermined volume of containment water and marine life successively between the plurality of storage facilities 12-15, etc., based on the different growth stages of the marine life being transferred. By way of non-limiting example, the conduits, pipes, etc. defining the path(s) of fluid flow 22 may have a diameter in the range of about 8 inches to about 30 inches. The smaller diameter conduits, pipes, etc. defining the path(s) of fluid flow 22 may be used to transfer an appropriate volume of containment water and included marine life, wherein the marine life will be smaller in size by virtue of being in an early growth stage. In contrast, the larger diameter conduits, pipes, etc. may be utilized to transfer containment water and included marine life which are larger and/or at a size appropriate for harvesting.

(13) Accordingly, with continued reference to FIGS. 1 and 2, the subsurface area generally indicated as 30 represents the location in which the different size conduits, pipes, etc. (schematically represented) defining the path(s) of fluid flow 22 are located. This subsurface area 30 should be properly located below the independent ground level 100 and/or revised ground level 100′, as described in greater detail hereinafter and should be sufficient in size, such as in the range of generally about 2½ feet, to accommodate the different sizes of the conduits, pipes, etc., having a preferred diameter of generally between 8 inches to 30 inches, which define the path(s) of fluid flow 22.

(14) In order to further facilitate maintenance of the containment water and marine life within the preferred, predetermined temperature range of generally about 14° C., while in and traveling along the path(s) of fluid flow 22, the predetermined depth 200 (generally about 3 feet to 4 feet) at which the location area 30 of the path(s) of fluid flow 22 is located, is further disposed at a spaced distance 300 from and above a local water table WT. Such a spaced distance 300 from the water table WT is preferably in the range of at least 2½ to 3 feet. While the spaced distance of the transfer assembly 20 from the water table WT may vary, such distance 300 should be sufficient to eliminate or at least minimize heat transfer from the water within an at least partially defining the water table WT to the containment water and marine life in the path(s) of fluid flow 22.

(15) In establishing an appropriate disposition of the transfer assembly 20, including the path(s) of fluid flow 22, between each of the ground levels 100, 100′ and the water table WT, aquifer, etc., reference will be made to a recognized standard including the North American Vertical Datum of 1988 (NAVD 88). In defining the NAVD 88 calculations are involved for the location of the local Mean Sea Level (MSL). As set forth in greater detail herein above.

(16) Accordingly, the embodiment of FIG. 1 represents an implementation of the transfer system 10 of the present invention in a geographical area where the water table WT is normally, historically or typically located a sufficient distance below the natural, exposed ground surface, defined herein as the independent ground level 100. In such a geographical location, the depth of the water table WT is sufficient to maintain the transfer assembly 20 and path(s) of fluid flow 22 a sufficient distance 200 below the independent ground levels 100 and above the water table WT, in order to facilitate maintenance of the path(s) of fluid flow 22 within the preferred temperature range of generally about 14° C. In such a geographical location, the water table WT is located at a recognized distance 400, generally in the range of about 3 feet, above the NGVT and further wherein the NGVT is located an appropriate distance 500, generally in the range of at least 11 feet, below the natural, exposed ground surface, defined herein as the independent ground level 100.

(17) The embodiment of FIG. 2, recognizes that in some geographical areas the water table WT, aquifer or below ground saturated soil is relatively shallow and comparatively close to the original or normal, exposed ground surface level 100 on which the plurality of storage facilities/tanks 12-15, etc. are operationally disposed/supported, as in the embodiment of FIG. 1. By way of example, the state of Florida includes a natural aquifer system (Floridan aquifer) as well as a shallow water table WT located in relatively close proximity to the original or normal exposed ground surface 100. Accordingly, in order to maintain the buried transfer assembly 20 and defined path(s) of fluid flow 22 out of heat transferring relation to the water table WT, the plurality of storage facilities 12-15, etc. may be disposed and supported on a raised, exposed ground surface level represented here in as a “revised ground level” 100′ .

(18) As such, the raised, revised ground levels 100′ may be man-made and constructed, such as by using ground or soil moving equipment or other techniques, so as to be disposed at a predetermined minimum height 600 above a corresponding normal or natural, exposed ground level, which would normally be at a height equivalent to the independent ground level 100. It is recognized that the predetermined minimum height 600 of the revised ground level 100′ may vary dependent on a particular geographical area, but in each practical application, the revised ground level 100′ of each of the plurality of storage facilities/tanks 12-15, etc. should be sufficient to facilitate the disposition of the path(s) of fluid flow 22 at a sufficient predetermined depth of generally of at least about 2½ feet to 3 feet below the revised ground levels 100′. Concurrently the path(s) of fluid flow 22 and the area 30 in which they are positioned, should be disposed a predetermined spaced distance 300, generally about a predetermined minimum of 3 feet to 4 feet, above a proximate water table WT. Moreover, as also set forth above with regard to the embodiment of FIG. 1, the disposition of the transfer assembly 20 and path(s) of fluid flow 22 will facilitate the maintenance of the predetermined temperature of and within the path(s) of fluid flow 22 at the predetermined temperature of generally about 14° C.

(19) As set forth above with regard to the embodiment of at least FIG. 2, in such a geographical location where the water table WT is relatively shallow, as set forth above, it generally considered to be located at a recognized distance 400, of generally about 7 feet, above the NGVT. Further, the height of the revised ground levels 100′ should be such that the NGVT standard is located an appropriate distance 500, generally about 11 feet, below the revised ground level 100′.

(20) It is further noted that while the system of the present invention is described as relating to an aquaculture system it is equally applicable for use with a recirculating aquifer system and the various storage facilities/tanks operatively associated there with.

(21) Since many modifications, variations and changes in detail can be made to the described preferred embodiment of the invention, it is intended that all matters in the foregoing description and shown in the accompanying drawings be interpreted as illustrative and not in a limiting sense. Thus, the scope of the invention should be determined by the appended claims and their legal equivalents.
