Due to the high price of grouper, it is generally only tasted at festive dinners or banquets.

Grouper also has its special position in China culture. According to traditional folklore, grouper is a kind of fish that symbolizes and brings good luck. Its shape is similar to that of "stone", which means perseverance, keeping peace and increasing family wealth, so it is often used in weddings and major festivals. In addition, grouper is regarded as a part of the traditional food culture in southern China, which represents the cooking skills and special cuisine of Guangdong and has certain local cultural value.

Due to the high price of grouper, the market circulation is limited to some extent.
