ている。Conventionally, as a substrate for oyster cultivation, a large number of disc trays made of a synthetic resin or an inorganic material are simply stacked and used in a state of being suspended from a raft. This disc tray is provided with irregularities on its upper surface to improve the adhesion of persimmon seeds (oyster larvae) and prevent falling off, and further provides a mesh curtain around the stacked disc trays (JP-A-49-131892). Has been proposed.

なくなかった。[0004] However, these conventional oyster cultivation bases (trays) are clearly improved in workability as compared with those using the conventional scallop shells, but still adherence of the oyster species and resistance to falling off once attached. (These are also referred to as adhesiveness.) The productivity and workability were not good. In addition, because little consideration is given to recycling,
In many cases, the treatment after the mass production and use of the tray was troubled.

The multi-layer tray during curing was constructed by inserting it into the hole at the top of the umbrella of the tray.However, in this state, the handling of placing and transporting was extremely poor, and the space factor was extremely poor and the efficiency was low.

When the upper end is strongly pulled (the upper part may be fixed and the lower part may be pulled in reverse), the locking part K comes off and becomes straight through a wave shape as shown in FIG. It looks like skewers. In this case, since the space factor can be extremely increased when the apparatus is placed or transferred, workability is remarkably improved.
