The word "eo" is a Chinese character used to mean fish, and the word "chi" is a character that means fish in the old Korean language. In other words, in Korean, even fish that end with cheese are mostly fish in Chinese characters. A good example is to write hairtail and anchovies in Chinese characters, door and abbreviation, respectively.
According to the link above, it is like this. According to this content, there is no difference in appearance, but it seems to be simply a difference between Chinese characters or Korean.
