〈産業上の利用分野〉
本考案は、コンクリ−ト水路内での魚類その他
水棲動物の生息環境を維持するために開発された
漁礁ブロツクに関するものである。[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a fishing reef block developed to maintain a habitat for fish and other aquatic animals within a concrete waterway.

It was just doing something.

ので適当な生息環境とはなり得なかつた。 Attempts have also been made to create habitats for fish and the like by creating holes in the side walls of concrete waterways. However, because the light from natural light does not reach the depths, and during droughts, there is not enough water left in the hole, so it could not be a suitable habitat.

が死滅する漁礁としての目的、機能を十分に果た
し得ない。 Fishing reef blocks can be seen in Utility Model No. 59-144037 and Utility Model No. 54-112792. What must be considered in such fishing reef blocks is the protection of fish in the event that water flow is stopped in the waterway formed by the waterway block, or the flow of water is stopped due to periods of dry water, etc. However, in either case, if the flow of water stops, all the water will disappear, and all aquatic animals will die, meaning that they will not be able to fully fulfill their purpose and function as fishing reefs.
〈考案が解決しようとする問題点〉

る。<Problems to be solved by the invention> The main purpose of providing the protrusions on the bottom of the waterway block mentioned above was to reduce excessive flow velocity, and it did not go far enough to provide a sufficient habitat for fish. .
In other words, even in times of drought, the water remains deep enough for fish to live in, and a certain amount of aquatic plants can grow, but they are washed away by external enemies and by excessive current speeds caused by increased water levels and slopes. Therefore, there was no place for them to escape, and it also could not be a suitable breeding ground.

る。<Means for solving the problem> Therefore, in the present invention, in order to provide a sufficient habitat for fish etc., a waterway block with multiple protrusions provided on the bottom almost perpendicular to the direction of water flow is used to prevent water from drying out. Taking advantage of the fact that a water puddle is left even at times, the waterway block has fitting parts 12, 12 at both ends that are shaped to fit into the protrusions 5, and spans between the protrusions of the waterway block. They developed a fishing reef block that had a shape that could be covered over the corner formed by the bottom and side walls of the reef, and had a cutout or side hole in the side edge.

This creates a habitat where only fish and other species can enter and exit.

It also allows natural light to enter the habitat.

所を提供する。 Conventionally, the area surrounded by the protrusion 5 and the side wall 7 of the concrete waterway bottom 6 provided a habitat for fish, but the present product provides a habitat for fish that is most suitable for fish. Improvements were made to maintain a suitable habitat. In such fishing reef blocks, water flow is reduced, and sediment accumulates, creating an environment where aquatic plants and aquatic insects are likely to grow, and the food and fish that are generated are not washed away by excessive current speed. Provide good feeding and breeding areas.
