の様子を映し出すこともできる。The artificial rock reef 14 of the present invention is placed in the sea approximately 100 to 500 meters away (water depth 1
5 to 25 m), and as described above, this artificial reef 14 is sprayed with steel fiber reinforced mortar, and an underwater television camera 8 and an illumination device 13 using optical fibers 12 are installed at appropriate locations on the layer 4. Each of these is connected by a cable 15 to a monitor television and a light source installed in a facility 6 on land. By depositing the artificial reef of the present invention in the sea close to the shore, it is possible to artificially and easily create a suitable environment similar to an offshore diving point, making leisure diving safer and easier. It can be done easily. In FIG. 7, reference numeral 17 indicates a campsite located on an island 18 in the sea, 19 indicates a beach for diving lessons, 20 indicates a swimming pool, and 21 indicates accommodation facilities such as guesthouses and pensions. A leisure center can also be established around reef 14. For example, a hotel lobby, which is an example of facility location 6,
In a public bath or the like, it is also possible to display the state of the diaper and the ecology of fish and shellfish in the artificial reef 14 on a large-screen monitor TV.

する。The artificial reef of the present invention can be freely configured in its shape, size, weight, etc. to resemble a natural reef, and by being submerged underwater, it can artificially and extremely create an environment suitable for diving. It can be easily created and leisure diving can be performed more safely and easily. In addition, the artificial reef of the present invention has an underwater television camera placed at the appropriate place in the fiber-reinforced mortar sprayed layer, so it is possible to observe the condition of the diper underwater, and to ensure safety. In addition, the ecology of fish and shellfish can be observed at all times, and academic information and knowledge about fish and shellfish and fish reefs can be obtained.On the other hand, the fiber-reinforced mortar spraying is equipped with optical fiber illumination devices at appropriate locations on the layer. This allows for night diving, rock fishing, playing on the shore, etc., and also has excellent technical effects such as the ability to observe the ecology of fish and shellfish at night.
