Description

DETAILED DESCRIPTION OF THE INVENTION The present invention has been developed by considering the ecology of benthic organisms and the physical forces exerted under special conditions underwater, rather than enclosing benthic organisms in the water and making them live there. The purpose of this system is to satisfy the conditions for easy living in the sea and to prevent the invasion of harmful enemies, and it is characterized by cultivating living things in net enclosures suspended above the seabed with a certain crystallinity. .

Now, a specific example will be described with reference to the drawings. A float rod (2) made of foamed resin is tied and fixed to the upper edge of a lattice frame (1) made of hard synthetic resin.

The lower edge is covered with a fixed wire (
4) is fixed to form a unit net frame (a), a number of these are connected to form a net enclosure, and a link chain (5) is inserted through the lower edge of the laying net (3). It is. (6
) can be anchored to the seabed as needed.

In the case of benthic organisms in the fire, most of them float around in a wide area when they are young, but as they become adults, they settle down on the bottom of the water, where they are suitable for neutral life, and do not make any wide-ranging movements other than feeding activities. This left them vulnerable to damage from their enemies. The present invention connects the unit mesh frames (α) of the vertically floating lattice frame (1) with rods (2) to form an enclosure, and anchors (6)' the fixed wire (4) at the bottom.
The net (3) becomes the bottom of the enclosure due to the weight of the link enamel (5) which is attached to the lower edge of the bottom net (3).
The lattice frame (1), which always floats vertically, is placed in a vertically floating structure, and the abalones are cultivated while being insulated from the outside, so there is no damage from external predators. Since it is divided, there is no resistance even if an external force acts on it.
""-4+; Bay, 8 Ka. , □*k L 1□O 63K ``'''□ Upper frame lattice frame is made of synthetic resin, so the shape of the enclosure C is maintained, and the net will not get caught on protrusions on the seabed. Also, since it is divided, it is easy to repair, and
Since the entire structure is net-shaped, it can be installed according to the irregularities of the terrain, the anchor can be placed anywhere □, and there are only a few fixing points.

In addition, if the bait is constantly swaying due to waves and currents and falls down to the bottom of the water due to a large force, the remaining bait in the enclosure,
To maintain a good environment for living things by removing feces, carcasses of living things, etc., and to prevent harmful enemies from entering and dissipating due to the nature of living things that tend to approach moving objects.

As described above, the present application maintains a favorable environment for benthic organisms to live in, and at the same time, because of its flexible structure, it has superior durability compared to rigid structures. The effect is suitable for the cultivation of organisms that live in the area.

Claims (1)

[Claims] (1) An underwater benthic organism cultivation method characterized by cultivating benthic organisms in a net pen that is suspended at a certain height above the seabed and surrounded by a net frame. 2. Float rods made of foamed resin are bundled and fixed to the upper edge of the lattice frame made of hard synthetic resin, and the lower edge is fixed to a fixed wire together with the upper edge of the plastic and knitted bedding net to form a unit net frame. This abalone cultivation device consists of a large number of connected nets that form a net pen, and a link chain inserted through the lower edge of the net.
