Geographical distribution: Japan, the Korean Peninsula (North Korea) to the South China Sea, northern Taiwan, and intertidal areas.

Characteristics: The eye is found in flounder fish on one side of its face, but flounder fry are identical to normal fish, its eyes are on both sides, but by the end of the transformation period the eye gradually moves to one side, in normal the eyes are located on the left face which is known as the left side of the flat, or It is located on the flat right side. From an early age, Taiwan produced fish fry, but the flounder species feared the heat. In Taiwan, the problem of increasing heat during breeding is increasing. For this reason, this species is gradually disappearing from the Taiwan market, in contrast to the global market, which has grown in love with flounder species, after flounder There are marine gear imported from France, starfish imported from Japan and Korea, and Atlantic flat fish, which reach a length of 280 cm, and weigh up to 420 kg, and are imported from northern Europe and others. Taiwan is currently exploiting the waters of the deep layers of the eastern ocean, where the water temperature is less than 15 ° C, which also allows in the future the possibility of exploiting cold waters in the production of fry of this type of fish, in order to open new horizons in the markets of the cold temperate and polar regions.
