JPS5823236Y2 - Increase in abalone, sea urchin, etc., concrete blocks for aquaculture - Google Patents

Description

[Detailed explanation of the idea] Regarding the increase in abalone, sea urchin, etc., and blocks used for aquaculture.

In order to obtain marine protein resources, we use various methods to collect biological resources on the seabed, but if we simply harvest the sea, which is the main source of protein resources, the amount that can be collected will be limited and will decrease. There's plenty of possibility.

Therefore, in order to harvest abundant marine living resources without diminishing them, we must not only harvest naturally produced marine resources, but also use the ocean agriculturally to increase and cultivate marine products.

For this reason, it is necessary to improve the breeding effect by improving the conditions for food generation, and to provide a habitat with good catching efficiency.

The present invention was developed in response to these needs, and its purpose is to improve the conditions for the generation of food for abalone, sea urchins, etc., and to use concrete blocks as habitats that are easy to grow and catch. It is about providing.

In order to achieve the above-mentioned purpose, the present invention provides a bed for growing young on both sides of a concrete block to be installed underwater, and a cross-shaped groove in the bottom of the casing to form a bed for growing young. The present invention is characterized in that a central through hole and a through hole are formed so that a vortex is generated in the vicinity of the resident bed portion and the nursery bed portion.

Hereinafter, one embodiment of the present invention will be described based on the drawings.
Reference numeral 1 denotes a main body made of concrete, and 2 a nursery bed. A cross-shaped groove 4 is formed at the bottom of the main body 1 so as to protect and raise young shellfish 3 such as abalone and sea urchin.

Reference numeral 5 denotes a member bed, in which a groove I having a U-shaped cross section is formed so that the members 6 can be protected and raised and easily collected by hand.

Reference numeral 8 denotes a central through hole, and in this embodiment, two elongated holes are bored in series from the center of the upper surface of the main body 1 to the nursery bed 2, so that a vertical vortex A is generated in the groove 4. It is.

Reference numeral 9 denotes a through hole, which extends from the left and right sides of the upper surface of the main body 1 to the member floor 5.
In this embodiment, vertical vortex B is generated within the groove γ by drilling two elongated holes in series.

10 is a depression formed in the shape of an isosceles trapezoid. Then, the concrete block main bodies 1 having such a configuration are arranged side by side as shown in FIG. 2 so that the members 6 can easily collect them.

By adjusting the dimension H of the main body 1, the center of gravity can be placed downward to improve fixing performance.

The depth of the cut U-shaped groove I is set to a size that makes it easy to collect the fish by hand.

Seaweed tends to grow on the surface of the main body 1, especially near the corners, and young shellfish 3
or members 6 can eat through the central through hole 8 or the through hole 9.

As mentioned above, according to the concrete block for abalone, sea urchin, etc. breeding and aquaculture according to the present invention, the central through hole and the through hole cause a vortex effect in each groove, and seaweed and silica grow near the corners. This improves the settlement of larvae, which improves the conditions for food generation, promoting the landing of floating larvae on the nursery bed, and also the landing of adults on the adult bed.

By forming a cross-shaped nursery bed at the bottom of the concrete block, the young shellfish are less likely to be attacked by natural enemies such as fish and starfish, making it ideal for protecting and raising young shellfish.

In addition, by forming a U-shaped member bed on the side, feeding damage from the top is avoided, making it easier for members to settle in.
Furthermore, since it can be easily harvested directly by hand, it is possible to increase the amount of harvest, shorten operating time, and reduce operating costs.
