On the three sides of the sea, Korea is a riaside coast, with a large tidal stream, mud and sandy western and southern seas, and strong, deep waters deep and deep sea with rocks and sand. .

Various types of farming methods are used in this type of farming, such as a tree branch, a vine, a discharge, a catapult, a dragon, and a cage.

Particularly, the caged aquaculture is a method of culturing fishes and shellfishes, and cultivates fish species such as rockfish, rockfish and the like by making a cage with a relatively free net of seawater flowing through the net.

In recent years, caged aquaculture technology has been applied in accordance with the aesthetic effect of coastal pollution and coastal tourism, the better quality and the desire of modern consumers who prefer eco-friendly aquatic products, and cultivated in distant seas to establish coastal pollution-free sea- This is a study that is going on.

The facility for such a cage culture is a ladder-shaped channel that is connected to the buoyancy by a plurality of buoys, and a net is installed under the buoy to raise various kinds of fish.
