Description

Shellfish breeding apparatus and shellfish breeding method using the same

The present invention relates to a shellfish breeding apparatus and a shellfish breeding method using the same.

In general, shellfish is a generic term for a type of mollusca that has a calcareous shell, and includes Monoplacophora, Polyplacophora, and Prosobranchia of Gastropoda. and parts of the subclass Opisthobranchia, most of the subclass Pulmonata, most of the classes Scaphopoda and Bivalvia, and parts of the class Cephalopoda.

Among them, the bivalve shellfish (二枚貝類, Bivalvia) belonging to the bivalve family has shells on the left and right. These include Lamellibranchia and Septibranchia, such as clams.

In general, shellfish culture goes through the processes of seeding (採苗), larvae cultivation (稚貝養成), and harvesting (收穫). At this time, seedling is the process of obtaining seedlings, cultivating larvae is the process of growing in a state in which the life radius of phyllotaxis is limited through artificial management, and harvesting is collecting the larvae.

Briefly looking at each of the methods for cultivating larvae here, the raft type is a method of cultivating a larvae for cultivating larvae by hanging on a moxibustion frame, which is a raft. On the other hand, the rope type is a method of nurturing by floating the father and son on the sea surface, connecting them with a rope, fixing both ends with anchors, and then suspending the training ropes on the rope. In addition, the simple transplantation method is a method in which two rows of horseshoes are erected from the vicinity of the gantry to a depth of several m, and then the lower rope is hung on the weaving trees. It is a method of raising upright, and the dialysis method is a method of raising stones by placing stones on the exposed bottom surface between high and low tides.

However, the existing method as described above is difficult to maintain efficiently, and the whole process of work is difficult and difficult because it completely depends on manpower, and the effect of natural conditions such as the flow of seawater is large, so the production volume fluctuates greatly. .

Moreover, when a number of chives are attached to the lower lip, it is often the case that a large number of dogs form a lump, but there is no practical way to prevent this. .

The above methods are methods of culturing shellfish in the sea, etc., and these methods have a problem in that shellfish culture efficiency is greatly affected by the marine environment.

For example, Republic of Korea Patent Registration No. 10-1043008 is an invention related to a marine aquaculture facility, specifically installed in the sea with a difference in tides, defining a waterway through which seawater passes, and disposed along at least one side of the waterway. a frame structure providing a working space on the sea level provided along the periphery of at least one entrance to the aquarium and the entrance to the aquarium; And the open upper surface is above the sea level, and the lower surface sealed with the first mesh network is inserted in a one-to-one correspondence into the entrance to the tank so that it exists below the sea level. Disclosed is a marine aquaculture facility for shellfish including a tank in which is contained. However, the apparatus is an aquaculture facility installed in the sea, and there is a problem in that it is greatly affected by the marine environment, for example, typhoon, red tide, and the like.

In addition, Republic of Korea Patent No. 10-1644772 discloses an invention of a land breeding apparatus for infiltrating bivalve molluscs, specifically, in the apparatus for terrestrial breeding of intrusive bivalve molluscs, comprising: a breeding tank in which infiltrative bivalve molluscs are bred; a drainage tank located on the side of the breeding tank; a vertical diaphragm dividing the infiltrating bivalve terrestrial breeding apparatus into the breeding tank and the drainage tank; a horizontal diaphragm disposed at the bottom of the breeding tank and including a drain hole; a net disposed on the horizontal diaphragm; gravel disposed on the net; sand disposed on the gravel; a pedestal for supporting the horizontal diaphragm; and a breeding water spraying unit disposed at the upper end of the breeding tank to spray breeding water, wherein the pedestal has a pedestal disposed furthest from the drain tank longer than that of a pedestal disposed closest to the drain tank. It provides an infiltrating bivalve terrestrial breeding apparatus, characterized in that. However, since the device cannot simulate the photoperiod of the environment in which the shellfish grows, the environment of tidal changes, etc., there is a limitation in improving the efficiency of the shellfish breeding environment.

Accordingly, the inventors of the present invention have led to the present invention by researching a breeding apparatus capable of efficiently growing shellfish without being affected by the marine environment.
