DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an intermediate breeding basket used for the intermediate breeding of scallops, pearl oysters and other pearl oysters during the cultivation process.

[0002]

2. Description of the Related Art When cultivating shellfish, for example, scallops,
In order to efficiently grow scallops using the middle breeding basket, the scallops should be dispersed so that the density of scallops per volume of the middle breeding basket does not become too high as the scallops grow. It is important to transfer to another middle breeding basket.
In addition, it is preferable to use a large mesh for the middle breeding basket so that plankton, which becomes as much food as possible, passes through the inside of the basket to improve the tide. Furthermore, by periodically taking out the scallop larvae from the middle breeding basket and periodically removing mollusks such as barnacles and sea squirts and seaweeds attached to the surface of the scallop larvae, the landing volume is increased as a result. be able to.

[0003] For these reasons, scallop scallops are several mm long.
From the size of the middle to the size of 6 to 7 mm before shipping, from the middle growing basket having a mesh of about 2 mm from spring to autumn 3.5 mm, 4 mm, 6 m
m, dispersed in an intermediate growing basket having a mesh of about 9 mm and transferred. This work is called distributed work.

Meanwhile, a conventional intermediate shell breeding basket for shellfish is called a so-called Zabton basket, which comprises a square outer frame and a reinforcing bar connected between opposing sides of the outer frame and crossed in a cross shape. A quadrangular pyramid-shaped mesh bag is provided on the outside of the frame, the bottom of the mesh bag is attached to the frame, and an openable / closable slit shape is formed along one of the ridges of the quadrangular pyramid of the mesh bag. It is inserted by closing the opening and closing mouth straps on the meshes of both side edges at the mouth of the mouth and closed, and the suspension line is connected to the intersection of the reinforcing bar of the frame and the center of the bottom of the mesh bag, A configuration is known in which the upper portion of the suspension rope is inserted into the top of the quadrangular pyramid-shaped portion of the mesh bag and connected at the top. The intermediate shells for shellfish are connected in a plurality of stages by a suspension rope, and when not in use, the suspension rope is loosened and stacked in a flat state.

[0005] In order to use the shellfish intermediate breeding basket constructed as described above, the opening and closing mouth straps are manually laid on the meshes on both side edges at the mouth of the mesh bag of the middle breeding basket of each stage. The tip of the funnel is inserted into a part of the mouth, and the scallop is put into a desired number of scallop net bags using the funnel. Then, immersed in the sea together with the scallops containing the middle breeding basket and connected the suspension line to the raft moored at sea, and submerged vertically in the sea by the sinker attached to the lower end of the suspension line Support and cultivate scallops in this state. After growing for a desired period of time, lift the middle breeding basket out of the sea, pull out the mouth string and release the mouth, shake the middle breeding basket with the middle breeding basket down so that the mouth faces downward, and scallop scallop The mouth is opened by its own weight and the scallop is dropped. Thereafter, a desired number of scallop scallops are dispersed and thrown into an intermediate breeding basket having a mesh larger than that described above to grow them.

[0006]

As described above, in the conventional intermediate breeding basket for shellfish, before the scallop is thrown, the lanyard is inserted through the mesh on both side edges of the mouth so as to be hooked. It is necessary to remove the laces from the mesh when closing and taking out the scallops, and these operations require a lot of time and labor and are inefficient. This was a bottleneck in improving work efficiency.

[0007] In particular, when the scallop is small, the mesh is small, the mesh is clogged by adhesion of seaweed, dirt, etc., the tide is poor, and the growth of the scallop is hampered. In the rising season of the lunar water temperature, the scallops also grow rapidly, so it is necessary to carry out the dispersion work every tide.
During this dispersing work, especially in hot seasons,
If the fish are dried in the air or raised in a narrow aquarium, the scallop will be weakened, and when it goes offshore, it may cause obstacles such as growth delay. desirable. However, as described above, dispersion work takes time, so if there is a shortage of manpower or the sea is rough, take the intermediate breeding basket raised from the sea back to the port together with the scallop and disperse work on land. And the above-mentioned problems such as the delayed growth of scallop scallop cannot be solved.

[0008] By the way, the above-mentioned distributed work has been performed since the end of July.
It is performed several times in about two months from the beginning of October, but the number of scallops to be used in one intermediate breeding basket decreases with each distribution work, and the number of intermediate breeding baskets used increases. Therefore, the insertion and extraction of the lanyard is a difficult operation. Therefore, in order to use the intermediate breeding basket next time, it is necessary to outsource the work of inserting the lanyard into the net, and if it is used repeatedly, the running cost will increase as a result. Therefore, there is a demand for the provision of an intermediate breeding basket in which the scallop can be dispersed with a simple operation.

[0009] Therefore, an object of the present invention is to make it possible to easily and quickly store and take out larvae, thereby improving the efficiency of aquaculture and reducing costs. The aim is to provide an intermediate breeding basket for shellfish.

[0010]

Means for Solving the Problems In order to solve the above-mentioned problems, the intermediate shell growing basket of the present invention is raised so as to gradually incline outward as it goes upward from the outer edge of the bottom surface, and is formed into a dish shape. A formed bottom portion, a quadrangular pyramid portion continuing above the bottom portion, a mesh bag having a lid piece capable of opening and closing the mouth at the ridge portion of the quadrangular pyramid portion, and a square outer frame ,
A frame body provided on the bottom portion inside the dish-shaped bottom portion of the mesh bag and connected to the bottom portion of the mesh bag is inserted into the center of the bottom portion of the mesh bag and the top of the quadrangular pyramid-shaped portion, And a suspension rope capable of suspending the mesh bag, wherein the lid piece is configured so that one of the lid pieces can sink into the other.

In the case where the bottom of the mesh bag is formed in a dish shape as described above, both side surfaces of the corner at the inclined standing portion of the bottom of the mesh bag are overlapped with the outer end of the lid piece in a triangular shape. The inner edges of the mating portions can be connected.

Also, one or more reinforcing cores can be integrally attached to the lid along the longitudinal direction.
