The scientific name of the nine-bellied fish is the dragonhead fish, which belongs to the family Asteridae. It is also known as a female fish, a shrimp, a tofu fish, a dog spit fish, a dog's milk fish, a dragon fish, etc. Why is the dragon-headed fish called the nine-belly fish? It's quite interesting to say. Calling the dragon-headed fish a female fish (or a fish that spits out dogs) is a common name used by chefs in Guangdong. Perhaps it is because in the catering industry it is too unpleasant to call them fish, and the word "dog" in Cantonese is also used. The pronunciation can easily be mistaken for "Nine", "Mother", "Tu", and the pronunciation of "Di" is similar, so the chef in the kitchen calls it "Nine-Triple Fish", and Nine Bald Fish The names "Nine-Rabbit Fish" and "Nine-Rabbit Fish" are further misinformation based on the "Nine-belly Fish".

The nine-bellied fish has a long body and flat sides, generally about 15 to 26 centimeters, and weighs about 75 to 150 grams. The head is large, the eyes are small, the mouth has a large cleft, and the teeth on both jaws are densely populated, and the teeth are thin and sharp. The body of the fish is soft, mostly smooth and scaleless, except for a row of larger scales on the lateral line that reaches the tail fork. The head and back lines are brown, and the abdomen is milky white. There is one dorsal fin with only fin rays and no fin spines. There is a fin behind the dorsal fin. Small adipose fin, pectoral fin and pelvic fin well developed, approximately equal in length. The caudal fin is trifurcated, with a shorter middle lobe. The nine-bellied fish is mainly found in the Indian Ocean and the Pacific Ocean. It is produced in my country's South China Sea, East China Sea and southern Yellow Sea. Among them, the offshore areas of Wenzhou, Taizhou and Zhoushan in Zhejiang Province and the coastal areas of Fujian have more production. The fishing season is mainly in spring. Nine tripe fish is a fish that "die on exposure to light". It dies after being caught out of the sea and landed on shore. Because it contains a lot of water in its body, it is not easy to store, so it used to be processed into salt-dried products, that is, "faucet grilled".
