Definitions

  • the present invention relates to a tray for cultivating molluscs.
  • the invention has particular application in the cultivation of oysters but is also suitable for mussels and scallops and the like.
  • the following description refers to oysters only.
  • oysters are cultivated from juvenile stage to maturity within the inter-tidal zone, the oysters being grown in oyster trays situated between low and high tide.
  • Conventional trays are typically 6 to 9 feet in length and 3 feet in width.
  • Various materials are used in the construction although timber has been generally preferred.
  • Oysters are generally distributed over the floor of the oyster trays in spaced relationship from one another. In order to allow water circulation the oyster trays generally have a mesh floor.
  • the sides of each tray are generally wooden and require treatment to prevent rapid deterioration as a result of immersion in sea water.
  • the trays are generally supported on rails or racks so that the trays are situated in the inter tidal zone. Hitherto, the wooden sides of the trays have limited to some extent the lateral forces exerted on the oysters by virtue of tidal movement although under certain weather conditions the oysters have been found to be washed towards various areas of each tray. This results in the need to re-distribute the oysters over the floor of each tray by raking them.
  • trays are used in single layers, leading to a fairly inefficient use of the oyster lease area.
  • the trays are generally covered with a heshan type fabric or shade cloth to protect the growing oysters from predators such as fish.
  • a tray for cultivating molluscs comprising a floor section and upstanding walls surrounding said floor section, the floor section and walls each having areas of mesh-like structure incorporated therein to facilitate circulation of water therethrough.
  • the tray is constructed of plastic which is formed in an injection mold as an intregal structure. Being of plastic the tray does not require the treatment necessary to preserve it that wooden trays require. Another advantage of the embodiment having an integral structure is that the tray does not require assembly and is maintenance free, lasting several seasons compared to conventional wooden trays.
  • the walls of the trays incorporate lugs to allow the trays to be clipped together on top of each other.
  • Conventional trays cannot be usefully stacked on each other since the circulation through one tray to the next would be insufficient. This is so because conventional trays rely on water passing through the mesh in the bottom thereof, which mesh is covered by oysters thereby restricting the flow.
  • the advantage of the present trays lies in the lateral circulation provided by the mesh sections of the side walls. Furthermore, stacking of the trays reduces the risk of oysters floating off trays or being attacked by predators.
  • an individual tray or a group of trays stacked on top of one another is provided with a lid suitable for attachment to the one or top tray.
  • the lid may be solid or of mesh. Unlike conventional trays in which the solid lid would significantly reduce the free circulation of water therethrough, the mesh sides of the tray provide adequate circulation even if the lid were solid.
  • the tray is preferably designed with a grid-like structure in the floor section so that the shellfish do not bunch up when jostled in rough water.
  • this grid is 100 mm square, having a height of 5 mm.
  • the floor of the tray is preferably provided with 8 mm mesh.
  • strengthening ribs may also be provided in the floor section. For example these could be preferably 40 mm high and conveniently divide the tray area into six portions. These ribs also help to avoid bunching up of the oysters.
  • each tray is provided with a ring arrangement at each end which may be placed over a pipe secured into the floor of the lake or river etc.
  • each tray or group of trays may be provided with buoyancy, and in conjunction with the ring arrangement, the tray or trays can float up and down with the tide, at any predetermined level relative to the water level.
  • heat kill occurs when oysters are left out of the water for too long in the hot sun.
  • Figure 1 is a perspective view of a tray according to the present invention
  • SUBSTITUTE SHEET Figure 2 is a detail of the mesh areas of the floor and walls of the tray of Figure 1,
  • FIG 3 is a detail of the clip system for the tray of Figure 1
  • Figure 4 is a securing clip for attachment of the tray of Figure 1 to a float
  • Figure 5 is a locking clip with which to secure each tray of Figure 1 to the next,
  • Figure 6 is a plan view of the tray
  • Figure 7 is a lid for the tray
  • Figure 8 is a schematic diagram in side elevation of a pair of trays of Figure 1 attached together showing the way in which a third tray fits thereon, the trays being suspended from a flotation device.
  • FIG. 1 shows in perspective
  • Figure 6 shows in plan, an oyster tray which is a preferred embodiment of the invention.
  • the oyster tray 10 is an injection molded tray of integral structure having a floor 11 and side walls 12.
  • the floor 11 comprises a mesh structure 13, the mesh being 8 mm square in dimension.
  • Superimposed on this mesh structure 13 is a grid-like structure 14, the grid-like structure being 100 mm square in area and having a height of 5 mm.
  • Reinforcing ribs 15, 16 and 17 are provided on the floor 11 of the tray 10. Reinforcing ribs 15, 16 and 17 divide the total floor area 11 into six smaller areas.
  • Side walls 12 have areas 18 which also consist of an 8 mm mesh portion similar to the mesh portion 13 of floor 10.
  • the walls 12 are also provided with lugs 19 into which connecting elements 20 may be fitted. Pairs of lugs 19 are provided to allow stacking of several trays 10 by using alternate members of the pair as each row of trays is added. This is more clearly illustrated in Figure 8.
  • FIG. 3 an alternate connector 21 is provided having a hole 22 in the upper portion to receive a nylon cord or the like for securing the tray to a flotation device such as shown in Figure 8.
  • the connecting clips are shown in more detail in Figures 4 and 5 where Figure 5 shows the clip 20 having a pair of legs 24 and 25 at each end thereof which may be squeezed to pass through lug 19 and upon release legs 24 and 25 separate to engage in lug 19, being restrained from removal therefrom by virtue of lip 26. A thickened centre portion 27 of the connecting clip 20 stops the clip 20 passing right through lug 19.
  • Figure 4 shows a clip 21 for connecting the tray to a flotation device using a nylon cord, the clip 21 having its bottom half 28 identical to one half of clip 20.
  • the top half 29 consists of a flap portion having a central hole 22 therein.
  • Clips 21 may be secured to flotation device 23 by means of nylon cord 29 tied through hole 22 and around flotation device 23, as illustrated in Figure 8.
  • Tray 10 is also provided with rings 30 integrally formed in the end of the trays having holes 31 therein. These rings may be positioned on the poles 32 as illustrated in Figure 8.
  • a lid 33 for the tray, or group of trays is shown in Figure 7.
  • the lid can be conveniently tied to the upper most lugs 19 of the top tray 10 by means of connectors 34 or 35.

Abstract

On a mis au point un plateau de culture de mollusques, moulé par injection et à structure solidaire, comportant un plancher (11) et des parois latérales (12). Ledit plancher (11) comprend une structure à mailles (13) sur laquelle on peut superposer une structure en forme de grille (14), ainsi que des nervures de renforcement (15, 16 et 17). Les parois latérales (12) comportent des parties (18) en forme de mailles, similaires aux parties à mailles (13) dudit plancher (11). Les parois (12) peuvent également être munies de points d'attache (19) dans lesquels on peut adapter des éléments de connexion (20), afin de permettre l'empilage de plusieurs plateaux pour augmenter le nombre de plateaux par surface unitaire de l'exploitation ostréicole.
