Abstract

The present invention relates to a fish farming network, and more particularly, to a multi-layered fish farming network in which high-density fish farming is performed by constructing a multi-layered flat net as a bottom layer in an inland water circulation filtration system.

An example of a fish farming network used in the past is mainly used for cage farming, but not in the inner surface circulating filtration fish farming.

In the inner water circulation filtration method, digging the ground or building fish tanks on the ground to perform fish farming, and the farmed fishes rest on the bottom of the tanks, and depending on the species, they live and grow.

By the way, the inner surface circulating filtration of fish farming requires a high-cost, high-density farming to ensure economic feasibility, the high density farming is difficult due to the limitation of the flat bottom of the fish to rest, living. In order to solve this problem, it provides a multi-layered fish farming net, which is equipped with a flat-bottomed net in a multi-layer farming net, to secure a wide area of plane where fish can rest and live and to perform high density farming. .

The present invention relates to a fish farming network, and more particularly, to a multi-layered fish farming network in which high-density fish farming is performed by constructing a multi-layered planar net in the inner surface circulating filtration farming.

In the example of the conventional fish farming net, it is mainly used for cage farming, and the farming net is formed by connecting the lower flat net and the vertical circumferential net which are the bottom surface to each other, and used to fix the cage in the water. However, in the circulating filtration method, which is an inland water fishery, aquaculture tanks are formed by forming plastic tanks or cement concrete tanks, and the fish are introduced while circulating the aquaculture waters. The nets are not being used to grow, or to lean on the floor.

However, the fish will rest during activities, or depending on the fish, they will live on the floor at all, and the fish input will be limited according to the size of the floor area. In addition, high-density aquaculture must be carried out to secure economic feasibility. As shown above, a high density aquaculture is difficult due to the limited flat floor.

In order to solve the above problem, the present invention mounts a culture net in which a flat net serving as a floor consists of multiple layers in a culture tank.

Cultured nets laid in multiple layers increase the plane area with the lower flat net (1), the middle flat net (3), and the upper flat net (4), while the middle flat net and the upper flat net are spaced through the center. The aim is to ensure high density fish farming by ensuring that fish can migrate to each layer.

The farming net is made of octagon, and the multi-layered net of the lower flat net (1), the middle flat net (3), and the upper flat net (4) is laid, and each flat net (1 · 3 · 4) is transverse The connecting rod 11 is connected and bonded while wrapping the flat net along the octagonal circumference, and the fixing bar 6 is erected vertically at each of the octagonal edges of the lower flat net 1, the middle flat net 3 and the upper side. The flat net 4 is inserted and mounted in turn and connected to the fixing base 6 at a predetermined distance, and around each octagonal layer, a vertical net 2 is joined and laid to the flat net for each floor, and the lower flat net ( 1) A transverse reinforcement (7) supporting the weight on the lower side is laid and manufactured into an octagonal form net.

From above, the distance between each layer of the flat net and the mesh of the net are adjusted according to the depth and fish species of the entire farm.

1 is a plan view of a farming net, which is viewed from above, where T is a quadrangular farming tank of steel sheet, and the farming net is mounted on the farming tank T, and the farming net is mounted in an octagonal plane, The transverse connecting rod 11 is wrapped and connected along the circumference, and the vertically fixed guides 6 are connected to each corner of the octagonal corner, and the horizontal connecting rods 11 are connected to each other with the fixing rods 6. It maintains a rectangular shape.

The planar network shown above is the upper planar network 4, but the intermediate planar network 3 is also homogeneous.

The attached farming net is secured by the holder 6 so that it does not come into contact with the inner surface of the tank, thereby preventing damage due to friction with the tank when the fish farm is attached or detached. It will prevent contact.

5 represents the network space secured in the center of the farmed net, which is adjusted to less than one half of the total area of each flat net (1 · 3 · 4), and this space becomes the flow path of the fish.

The multi-layered fish farming net may be made of a single material such as a steel net, a plastic resin net, or a woven net, or a mixed net of plastic resin or a woven net may be manufactured.

From above, the multi-layered farming net can increase or decrease the number of layers in the flat net.

The farm can also be made round or quadrilateral.

Fig. 2 is a longitudinal cross-sectional view of the culture net, 6 being connected to a longitudinal perimeter net 2 vertically erected with steel fixtures and a planar net of multiple layers, with an unillustrated ring attached to the top of each anchor 6; This hook is used to connect the chain and hang on the hoist to temporarily attach and remove the aquaculture net.

1 is a lower flat net with a front mesh, and a reinforcing bar 7 is horizontally supported at the bottom of the net, 2 is a vertical net wrapped around the periphery, 3 is a middle flat net, and 4 is an upper flat net In the middle of the middle and upper plane network, a penetrated space 5 is secured through which the fish can freely move to each plane network.

Figure 3 is a longitudinal cross-sectional view of the culture net mounted to the culture tank, the upper side of the culture tank (T) is a hopper (Hopper type) is narrowed to the center while narrowing the lower portion, and bent 90 degrees at the point where the hopper type is made This is made, the column (8) is supported by this bending point, the culture tank (T) is raised and fixed, the column is fixed to the ground, the oxygen supply device (9) for supplying oxygen to the hopper-type space is laid It is.

The installation and operation of the multilayer fish farming net manufactured as above will be described.

The octagonal culture net is inserted and mounted from the top of the culture tank (T) by the hoist, mounted on the bending point at which the hopper type is formed in the culture tank, and fixed to the fixing plate (10) installed inside the upper part of the culture tank. There is some space between the farm and the tank.

When aquaculture net is installed, aquaculture water is introduced, and when fish is introduced, aquaculture is performed, while oxygen is supplied from the oxygen supply device 9 in the hopper type space below the culture tank, and the supplied oxygen is supplied into the culture tank through the network. As it spreads, the fish breathe this oxygen and move freely to the flat network of each layer to rest, and the fish that leans on the floor grows while living on the flat network.

As the fish grows, if it is required to move, sort, or clean the tank, the hoist can be operated to raise the farm to the top, where it can be moved, sorted or otherwise taken.

As described above, by multiplying the flat network of the farming net, a wide bottom surface is secured, and a high density farming is possible.

In the in-water circulation fish farming, fish lean on the floor when they are active and rest, and fish that lean on the floor take a lot of bottom surface, and when a large amount of fish is put into a limited farm, they collide and hurt each other. Growth may be delayed due to wear or stress.

In the present invention, by attaching a multi-layered farming network, the floor area can be secured widely in a culture tank of the same size, so that a large amount of fish can be introduced and fish can be farmed at a high density.
