There was a problem that shellfish were likely to be stolen.

In order to solve this problem, the 'shore coastal fishbed fish and shellfish both-side cages' were formed to settle on the bottom of the sea (Korea Patent Publication No. 1992-0000484).

The above facilities raise shellfish at the bottom of the sea and, if necessary, supply and discharge air to the flotation (100) to support the facilities above the sea by buoyancy, but it is difficult to maintain balance when the facilities rise or fall. there was.

In addition, the facility is settled on the bottom of the sea there was a problem that it is difficult to protect shellfish from natural enemies such as starfish.

The shellfish cage facility of the present invention is to solve this problem, by placing a cage for shellfish farming in the water, the shellfish inside the shell from the natural enemy mainly inhabiting the sea bottom and climatic factors caused by red tide and waves, etc. There is a purpose to protect.

In addition, through the supply and discharge of air and water in the buoyancy structure pipe is to lower or raise the cage to a certain position to maintain a good balance during the rise or fall.

There is also a purpose to secure a plurality of aquaculture vessels inside the buoyancy structure to prevent shellfish from being stolen or lost.
