In the figure, 1 is a reef body for young shellfish, and its overall shape is 1.
As shown in FIGS. 4 and 5, the material can be appropriately determined, and the material can be appropriately selected from durable materials such as concrete IJ-) and steel 2 synthetic resin.

On the upper surface of this reef body 1, a large number of grooves 2 are carved in parallel at regular intervals, and the bottom of the grooves 2 is further configured with recesses 3 and protrusions 4 arranged in a row in an alternating manner. ing.

The cross-sectional shape of the uneven parts 3 and 4 may be a continuous U-shape as shown in the figure, a continuous 7-shape, or a continuous U-shape, and the cross-sectional shape of the uneven parts is limited to It is not something that will be done.

Note that the formation of such a groove 2 having a large number of uneven parts 3 and 4 on the bottom is not necessarily limited to the upper surface of the reef body 1, and may be formed on the circumferential surface or the bottom surface of the reef body 1. .

このように構成された稚貝用礁体1は第6図に示すよう

In this way, the floating larvae 5 contained in the seawater that flowed into the ditch 2
is deposited on the inner surface of groove 2, as shown in Fig. 3, and
It then concentrates on the corner s6 inside the groove 2 and continues to grow.

Those that have grown to a certain extent descend from this reef body 1 and grow further on the nearby ocean floor. In that case, if the mother-shell reef 7 as shown in FIG. 7 is properly sunk to the seabed with 8 groups of stones interposed as shown in FIG. 6, it will be more effective for subsequent growth. In addition, in FIG. 6, 9 indicates a breaking wave.

In the groove structure according to the present invention, unlike a groove that simply does not change, water easily accumulates on the inner surface of the groove, and there are many deposition surfaces, which is good for the deposition of young larvae. In addition, the uneven structure creates many corners, which increases the number of contact points with the substrate, reducing water loss and wear and tear caused by water flow, and the shade of the unevenness effectively protects against feeding damage by living organisms.

(2) Since there are irregularities inside the groove, the tidal current is likely to be relaxed or stagnate, and cone particles are therefore likely to be deposited therein. In particular, corners with irregularities have many contact points with the individual foil, and the stability after attachment is good at the corners, reducing the risk of being washed away by currents.
