Grouper is one of the specialties that Guangdong people like. It is a kind of marine fish with delicious meat and high nutritional value, and it is also a common high-grade fish dish on the table of Guangdong people. The meat of grouper is tender and delicious, and it can be eaten by steaming or boiling, and it is rich in nutrients, such as protein, trace elements and calcium, which is very beneficial to health. Because grouper is expensive, it is usually only tasted at holiday dinners or banquets.

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

Due to the high price of grouper, the market circulation is limited to some extent. In recent years, with the development of economy and the upgrading of catering consumption, people's demand for grouper is also increasing, and at this time, the counterfeiting phenomenon of grouper appears. In order to protect the interests of consumers, many merchants have established strict fish quality detection and traceability systems to ensure the quality and source of groupers are reliably guaranteed, thus providing consumers with better and safer food enjoyment.
