Sand fish is very greedy, and eats anything that can be swallowed, such as small fish, shrimp and nereis. Therefore, it grows very fast, lays eggs every year, and grows rapidly after hatching. When the first frost comes, some of them can be close to 65,438+0 feet long and weigh more than four ounces. Although the sand light fish grows very fast, it can only be changed once a year and can only grow.

The meat of the sand fish is delicate and delicious. It can be used for braising in soy sauce and making soup. It has been listed in China's famous cookbooks. There is a folk proverb in Lianyungang, "Shaguang mutton soup in October", which shows that winter is the golden season to eat Shaguang fish. According to "Edible Materia Medica" records, Shaguang fish "warms the middle warmer, benefits qi, strengthens yang and tendons, and benefits blood vessels ...", which is very nourishing and nutritious.
