Since it falls inside and cannot be used at all, as shown in FIG. 6, a large number of fixing plates A having feeding holes F formed at required intervals are stacked horizontally with spacers B at required intervals. It has also been attempted to feed an artificial bait on the fixing plate A on the upper surface using a breeding device E ′ to breed, but in the breeding device E ′, the breeding device E ′ wanders for a long time until the juveniles eat. Feeding efficiency is poor because it has to be moved, and the fed food is not only scattered inhomogeneously but also extremely unstable.
In addition to the consumption of dissolved oxygen due to the oxidative decomposition of stagnation and adhesion on the surface, there is an inherent risk of causing illness due to putrefaction and the like.

In addition, the side-to-side mating side is provided with the upright connecting member 3 provided with the holding groove 30 which can be held by the one side 26 of each of the growing and fixing plate portions which are lined up at a required interval. Since this single upright connecting member 3 is usually fitted and held together with about 6 to 8 growing and fixing plates 20, it is preferably about 20 × 30 cm in strength, preferably synthetic resin square or hollow square. In addition, the juxtaposition interval of the breeding and fixing plates 20 is about 70 in the breeding of juvenile shells having a shell length of 20 to 30 mm.
It is considered that about 80 mm to 80 mm is preferable, and therefore the claws 30 are formed at intervals corresponding to the vertical intervals, and the width of the claws 30 is also formed corresponding to the thickness of the growth fixing plate 20. As a matter of course, the growing and fixing plate 20 is formed of an opaque synthetic resin having a thickness of 2 to 3 mm at most, and thus the thickness may be formed in this thickness.
