Definitions

  • This invention relates to oyster shellfish aquaculture and specifically to the shaping and cleaning of oysters by means of tidal and current movement.
  • oyster farmers utilize cages, baskets, bags, trays or other containers that are moved, operated, or handled solely by human interaction with the grow-out container.
  • tumbling is required to shape the oyster to a deep cup, rather than flat shell, for a bigger meat size per shell ratio.
  • Some grow-out locations have bio-fouling problems that require oysters to be cleaned in tumbler washers or power washed in the containers. Bio-fouling occurs when organisms in the water column attach to the oyster, inhibiting growth and feeding opportunity. For example, this is the case with mud worms that setle on the oysters, creating a blanket of mud or silt over the oysters.
  • Tumbling for shape requires dumping each container into a land or vessel based tumbler, which chips some new growth to encourage the oyster to grow a deeper cup.
  • Tumbling for shape in sub-tidal applications requires taking every container off the botom and dumping them into a vessel based tumbler to chip new growth and wash the oyster. The washing needs to take place if the bio-fouling has proliferated, regardless whether or not the oysters need to be chipped for shaping.
  • TROSC Tidal Rotating Oyster Shaper and Cleaner
  • a TROSC apparatus comprising an outer frame, a containment cage supported by the outer frame, and a plurality of containers designed to hold oysters, the containers being located and maintained within the containment cage.
  • a circular end member having outwardly extending teeth which circumscribes the end member, is mounted on each lateral end of the containment cage.
  • At least one passive energy capturing pawl is configured to contact and engage the teeth, such that upon the introduction of a source of passive energy, the pawl is caused to rotate. This results in the rotation of the end members, the containment cage, and the containers, which thereby rotate the oysters within the containers. Rotation of the oysters consistent with every other tidal or current cycle serves to shape and clean the oysters.

  • FIG. 2 illustrates eight containers located within containment cage 4, the containers being held in place by straps 3 and 5.
  • Containment cage 4 configured to hold multiple containers, is supported by outer frame 6 via rotatable end stub shafts 8 and 9 which support and allow the containment cage to rotate on its longitudinal axis with every rising tide.
  • Frame 6 holds containment cage 4 off of the grow-out floor base.
  • Mounted on the lateral ends of containment cage 4 are end members, in this embodiment taking the form of circular plates 10 and 12 which have teeth 14 and 16, like gear wheels or sprockets, circumscribing each plate.
  • Horizontal float bar 20 outside contaimnent cage 4 has floats 22 and 24 attached that create buoyancy as the tide rises vertically.
  • Linear pawl members 26 and 28 are rotatably connected at ends 27 and 29 respectively to float bar 20 The other ends of pawls 26 and 28 contact teeth 14 and 16 of plates
  • TROSC 1 can be manufactured in different sizes to hold more containers, in all its sizes, plates 10 and 12 on the lateral ends of containment cage 4 are connected by elongated rods or pipes 35 which make up outer frame 6.
  • Lift arm members 34, 36 and 37 extend from horizontal float bar 20.
  • Stub shafts 8 and 9 are bolted at either end of containment cage 4.
  • Bearings 38 and 39 on each end of shafts 8 and 9 are bolted to the outside of frame 6 as well. The bearings allow for the rotation of containment structure 4.
  • a second embodiment of the invention is provided for submerged, sub-tidal applications. See FIGs, 8-15.
  • a single TROSC apparatus 40 comprises cylindrical, drum-like containment cage 41 made up of containment cage rings 44. Containment cage 41 is configured to hold a plurality of individual containers 42. Containment cage 41 is supported in part by outer frame 46 via rotatable through shaft 48, which allows the containment cage to rotate on its longitudinal axis with the movement of ocean currents.
  • Shaft 48 is supported on frame 46 at ends 54 and 56 of the shaft. Shaft ends 54 and 56 are supported by bearings located within sleeves welded to frame 46.
  • FIG. 12 shows one of the shaft ends in which bearing 92 circumscribes shaft 48 located within sleeve 90, which in turn is welded to frame 46.
  • containment cage 44 Mounted on the lateral ends of containment cage 44 are circular end members, in this embodiment taking the form of ring plates 50 and 52 which have teeth 51 and 53, like gear wheels or sprockets circumscribing each ring plate.
  • Pawl member 60 comprises energy capturing pawl bar 62 from which lateral swing arms 64 and 66 downwardly extend. Pawl plates 68 and 69 are pivotably attached to pawl bar 62. Swing arms 64 and 66 of pawl member 60 are rotatably connected near ends 54 and 56 of shaft 48, which allows the pawl member to rotate in tandem with the shaft. When pawl member 60 is connected to shaft 48, pawl plates 68 and 69 of pawl bar 62 contact teeth 51 and 53 of ring pl ates 50 and 52
  • anti-reverse stop 80 connected to outer frame 46, prevents containment cage 41 from reversing direction. Containment cage 41 is thus held in a static position while pawl member 60 ratchets back across teeth 51 and 53 to its starting position. Pawl member 60 is now in its original position, waiting for the current to again change direction.
  • Passive energy capturing cones 82 and 84 can be attached to pawl member 60. These cones provide an optional means of increasing the energy capturing capacity of TROSC 40, thereby increasing the rotational efficiency and effectiveness of the system.
  • Marker buoy 86 attached by line 88 to pawl member 60, floats at the surface of the water. Buoy 84 serves as a lift and marker. The length of line 88 will determine the depth of water in which TROSC 40 is deployed. Line 88 can also be used to lift TROSC 40 out of the water for routine maintenance and oyster container grow-out density changes.
  • FIG. 14 shows a plurality of TROSC apparatuses 40a, 40b, 40c and 40d, mounted for placement on the ocean floor, on outer frame 94 which is large enough to support all the TROSC units.
  • no containers are shown within the containment cages of the TROSC units.
  • FIG. 15 show ' s each of the TROSC units filled with containers 42.
  • the movement of the TROSC apparatus of both embodiments tumbles oysters gently, but consistently, with every rising tide of nature and the naturally occurring passive energy of tidal currents. This creates a more consistent shape of the oysters.
  • the tumbling effect also removes any bio-fouling that has set on the oyster, but has not had enough time to proliferate to hinder growth or cause mortality.
  • Use of the TROSC apparatus of the present invention reduces the number of vessels needed to operate an oyster aquaculture farm, when compared to a containment cage or like structure that uses manpower to wash and tumble oysters.
  • the use of passive energy from the natural rising and falling tides replaces the excessive manpower required to clean and shape oysters.
  • Reduction in manpow r er reduces impacts on the environment through carbon footprint as well.

Abstract

Un appareil rotatif marémoteur de mise en forme et de nettoyage d'huîtres comprend un cadre externe, une cage de confinement supportée par le cadre externe, et une pluralité de contenants conçus pour contenir des huîtres, les contenants étant situés et maintenus à l'intérieur de la cage de confinement. Un élément d'extrémité circulaire ayant des dents s'étendant vers l'extérieur qui circonscrit l'élément d'extrémité est monté sur chaque extrémité latérale de la cage de confinement. Au moins un cliquet de capture d'énergie passive est conçu pour entrer en contact et venir en prise avec les dents, de telle sorte que, lors de l'introduction d'une source d'énergie passive, le cliquet soit amené à tourner, ce qui entraîne la rotation des éléments d'extrémité, de la cage de confinement et des contenants, ce qui fait tourner les huîtres à l'intérieur des contenants. Une rotation continue des huîtres permet de mettre en forme et de nettoyer les huîtres.
