It should be called dog light fish, also called sand light fish.

Shawan fish is a specialty product of Changyi City. It belongs to the Goby family and is a species of spear-tailed goby. It is a large goby native to seawater and brackish water.

Shawang fish is also known as push wave fish, sand light fish, ground dragon fish, sky wave fish, light fish, and its scientific name is Acanthogobius hasta.

The Shaguang fish has a big mouth and is a glutton for eating anything it can swallow, such as small fish, shrimps, and lugworms. Therefore, it grows very fast. It lays eggs during the Qingming Festival every year and grows rapidly after hatching. When frost comes, some can grow nearly 1 foot and weigh more than 4 taels. Although the Shaguang fish grows very quickly, it can only grow once a year and can only grow a few feet long.

Shaguang fish has fine flesh and delicious taste. It can be braised or made into soup. It has been included in "Chinese Famous Recipes". There is a folk proverb in Lianyungang that "Shaguang race mutton soup in October", which shows that winter is the golden season for eating Shaguang fish. According to "Food Materia Medica": Shaguang fish "warms the body and replenishes qi, and is the main food to strengthen the yang, strengthen the muscles and bones, and benefit the blood vessels...", and has great nutritional value.

As for the Shaguang fish, there is also a mythical legend (I heard it from my grandfather when I was a child): Because the Tuilang fish is particularly willing to grow, it also has the ambition to become the dragon king. Pomfret (Pompano)" were talking together, and he accidentally revealed the secret in his heart. He said to "Pompano": "I will grow up once a year, and if I don't die for ten years, I will eat the old Dragon King." To please the Dragon King, he told the Dragon King exactly what Tui Lang Yu said. The Dragon King was furious and said, "Okay! Will it grow, right? I'll tell it to reborn once a year." In this way, Tui Lang had to reborn once a year. , so it will never be able to claim hegemony. And because "Pompano" loves to tell stories, everyone gave "Pompano" a nickname - Xiaozui.

Very delicious and cheap. The meat is tender but prickly. Some are dried, some are braised, and some are stir-fried.
