Description

[Detailed explanation of the invention] "Industrial application field" This invention is a box that is sunk to the seabed and filled with clay pipes, corrugated plates, sand and stones, etc., and is inhabited by young fish and shellfish. This invention relates to a fish and shellfish breeding reef that is characterized by being designed to measure proliferation and growth while at the same time preventing poaching.

``Conventional technology'' Conventionally, in order to propagate abalone, octopus, sea urchin, sea cucumber, etc., the larvae were artificially hatched and grown to a certain size, and then placed in the desired habitat, such as a rocky area or stone. They planned to grow and multiply by leaving them in mud and other places to live.

``Problem that the invention aims to solve'' As mentioned above, even if you leave young fish and shellfish in their desired habitat and measure their growth or reproduce, the range of movement of the young will change as they grow. Wide,
In addition, they were often captured by poachers, and the harvest was low compared to the hardships they experienced in growing them, making them a problem for poachers.

``Means for Solving the Problems'' Therefore, the present invention was proposed to solve the above-mentioned inconvenience, and its structure consists of erecting supports around the periphery, and a number of strips between the supports. The pillars are installed at regular intervals, and the pillars are set higher than the bottom plate between the pillars. A weight plate of a size that can fit inside the pillars is passed loosely through the pillars, and a rubber plate is placed on the weight plate. A hollow part is integrally provided, into which air can be injected and discharged. This product is sunk to the seabed, air is injected into the rubber hollow part to float the weight plate, and a box filled with corrugated plates, clay pipes, earth and sand, etc. is stored inside the support, depending on the species to be cultured. This device is used by exhausting air from a hollow rubber section and lowering a weight plate. When fish and shellfish larvae are released into the hollow section for aquaculture, large fish enter and exit the interior of the fish reef. The larvae are not attacked by external enemies, and the inside has a dark area, which is convenient for them to live in. Also, since they cannot be accessed by the surrounding area, they are not poached, which is good for breeding.

Next, the structure will be explained with reference to the drawings. Supports 1 are installed at the four corners, but if the distance between the supports is long, they may also be installed between the supports. Reference numeral 2 denotes a bottom plate, which is integrally provided at the lower part of each column 1, and has a column 3 erected high above the center thereof. Reference numeral 4 denotes a strip plate attached between the supports 1, 1, and a large number of strip plates are attached in an inclined manner with a fixed interval (an interval that cannot be accessed). Reference numeral 5 denotes a weight plate, which is made of concrete or the like and has a size that allows it to fit inside the column 1, and is inserted through the column 3 so that it can move up and down. 6 is a hollow part made of rubber, and a weight plate 5
A pipe 7 through which air can be injected and discharged is attached to the upper part. A bait inlet 8 is provided at the four corners of the weight plate 5, and a rubber piece 9 is attached from the inner periphery of the bait inlet 8 toward the center. 10 is a corrugated plate,
This is made of corrosion-resistant iron plate, aluminum, stainless steel, etc. A kerf 11 slightly larger than the diameter of the columnar body 3 is formed from the center of one side of the corrugated plate 10 toward the center. 12 is a clay pipe.

"Function" Since the present invention has the above-mentioned structure, when it is submerged in the sea and air is injected into the rubber hollow part 6 through the pipe 7, the weight plate 5 floats as shown in Fig. 1. do. Then, the corrugated plates 10 are stacked alternately in the upper and lower layers as shown in the drawing, or a large number of clay pipes 12 are inserted, or earth, sand, and stones are placed in a box and inserted into the rubber hollow part. Pipe the air inside 6 to 7
When the weight plate 5 is discharged through the pillar 1, the weight plate 5 descends as shown in FIG. When cultivating abalone, a corrugated plate 10 is used, when cultivating octopus, a clay pipe 12 is used, and when cultivating sea cucumber, sand and stones are placed in a box. Feed suitable for aquaculture is fed through a feed inlet 8 against a rubber piece 9.

``Effect of the invention'' The method of the present invention releases young fish and shellfish into the interior of the fishing reef, but it forms many dark areas and is surrounded by the strip plate 4, so it is not large. Fish can live there as a safe haven without being disturbed by waves, and even when they grow up, they do not migrate outside, making it a good breeding reef. To take out the grown fish and shellfish, air is injected into the rubber center part 6 from the pipe 7, and the weight plate 5 is floated by the rubber center part 6, and the corrugated plate 4 or clay pipe 12 inside is lifted up by the rubber center part 6.
Fish and shellfish can be captured by taking out the rubber hollow part 6, and by discharging air from the rubber hollow part 6, the weight plate 5 sinks and is closed, making it easy to take out and release. Can be done. Further, since strip plates 4 are provided at regular intervals around the outer periphery, it is impossible to insert one's hand into the interior, thereby preventing poaching. Therefore, the present invention has the effect that fish and shellfish can live safely, the fish and shellfish that have settled there do not move elsewhere, and most of the released juveniles can be captured and are effective. play.
