Abstract

(57) [Summary] [Purpose] The fishery seedlings for growing and growing seaweeds such as kelp are designed so that they do not hang down on the seabed so as to prevent sea urchins from eating damage while avoiding friction with the sediment. Provide seedlings for fisheries. [Structure] A seaweed seedling base for propagating seaweed of aquatic fishery, in which a columnar float 2 and an anchor portion 3 are connected by coins and a linear strip 4 having elasticity, and Seedling base for fishery with mesh sheet wrapped around the surface of columnar float

Description

[Detailed description of the device] (A. Purpose of the invention) <Industrial application fields> This invention relates to a fishery seedling base for multiplying and cultivating seaweed such as kelp in the fishery industry. To do. <Conventional technology> Conventionally, when growing seedlings of kelp in natural waters, stone blocks or concrete blocks should be used. I used it as a weight and tied it to the rope and put it in the sea. (Problems that the device tries to solve) However, if the conventional method is used, and if a large amount of kelp, etc. have settled, the ropes A seaweed that hangs down on the bottom of the sea, becomes the food of sea urchins, and is rubbed on the bottom material. Was not growing well. This device prevents the seedling from hanging down to the seabed to solve the above-mentioned problems. The structure is designed to prevent sea urchins from eating damage. (B. Device configuration) In order to achieve the above object, the seedling base according to the present invention serves as a columnar float and an anchor. The weight portion is connected by a hard and elastic wire. In addition, seaweed is stretched as a rough surface such as wrapping a mesh sheet around the columnar float. Try to improve (Action) With the above configuration, the seaweed-attached floating bodies of seeds and seedlings are always located between the hollow seas through the striatum. Therefore, depletion of seaweed due to sea urchin feeding damage and rubbing on the sea floor is prevented. <Example> The following is an example of a fishery seedling base 1 according to the present invention shown in the accompanying drawings. explain. FIG. 1 is a perspective view showing the whole fishery seedling base 1 according to the present invention. The fishery seedling base 1 is composed of a float 2, an anchor portion 3, and a connecting wire 4. The float 2 has a columnar shape and is made of a plastic foam or the like and has a buoyancy force. It is desirable that the part has a rough surface so that seaweed roots can be easily attached. The anchor part is made of iron, concrete or other specific gravity to serve as a weight. It resists the buoyancy of the upper floating body 2 and the buoyancy of seaweed that grows on the floating body, which is made of a white material. Add weight to the weight. Titanium wire that is hard and elastic in connection with the anchor part 3 and is resistant to corrosion by seawater, A stainless wire 4 or the like is used. With this structure, the fishery seedling base 1 is seaweed previously cultivated in a land tank on a floating body. By binding the seedlings 5 and dropping them on the seabed of the target sea area, the seaweed can be easily propagated. It can be done reliably. <Effect of device> This device has the following effects. Seaweed can grow regardless of the condition of the rock surface on the seabed. In so-called Isoyaki Seaweed grows regardless. When the seabed is sandy land, the anchor part 3 that has landed on The car body is buried in the sand, but the connecting wire 4 stands upright to keep the float body hollow. The surrounding sandbox can be used as a seaweed forest without damaging the grown seaweed. Since the connecting part is a line, it can respond flexibly to the current resistance and, on top of that, reliably prevent the sea urchin from climbing. You can stop. When harvesting seaweed, pull up all the seedlings 1 and take only mature seaweed and re-enter into the sea. To do. This seedling base 1 is a fishing operation in the sea area where it is installed, that is, a long line, It will not cause any problems with nets, single fishing, bottom nets, etc. When installing on sandy ground, adjust the length of connecting wire 4 depending on the depth of movement of sand at that location. To do. Is the anchor part of the seedling base 1 to be put on the bedrock a young or juvenile of the organism growing there? A compound effect can also be expected by having the structure 7 as a curry house.
