The yellow croaker, also known as the yellow croaker, is the collective name for a genus of yellow croakers in the family Stenotrichidae. Born in the East China Sea, there are two hard stones in the head of the fish, called otoliths, so it is also known as the stonehead fish. The white swim bladder in the belly of the fish can be used as fish glue, which has the effect of stopping bleeding and can prevent hemorrhagic purpura.
Expanded Information:
. p>The yellow croaker is divided into large yellow croaker (Pseudosciaena crocea) and small yellow croaker (Psendosciaena polyactis), respectively, one of China's four major marine industry species. The big yellow croaker is also called big first, golden dragon, cucumber fish, red melon, golden dragon, cinnamon yellow croaker, big king fish, big yellow replica bags; small yellow croaker is also called plum, plum fish, small king fish, small first, small spring fish, small cucumber fish, thick-scaled boy, flower fish. All belong to the order Scleractinia, Perchiformes, family Stonefish, yellowtail genus .
The yellowtail was once one of China's important economic fish, endemic species unique to China, widely distributed in the south of the Yellow Sea in the north, through the East China Sea, the Taiwan Strait, south to the South China Sea east of the Leizhou Peninsula. The fish is a warm-temperature cluster migratory fish, often inhabiting the offshore middle and lower layers of the water depth of 60 meters or less. The reproductive seasons of the fish are spring and fall, and during the reproductive period, the fish migrate in batches from the offshore wintering area to the offshore for reproduction. As a valuable economic fish, the yellow croaker has long been favored by consumers. However, due to overfishing, the resources have been seriously damaged.
The appearance of the yellow croaker:
1. The body of the yellow croaker is nearly rectangular and laterally compressed, with the dorsal and ventral margins convex in front and low at the back.
The body length is about 30 centimeters. The head is large and laterally compressed, with a rounded muzzle. Eyes equal in size and laterally superior; interocular septum wide and slightly convex. Nostrils 2 on each side, anterior nostrils round and small, posterior nostrils elongate, larger, close to eyes. Mouth anterior, broad and oblique. Upper and lower jaws equal, lips thin; maxilla retractable. Margin of anterior gill cover bone serrulate, posterior end of gill cover bone with a flat spine. Gill pores large, gill cover membrane not connected to isthmus. Gill rakers longer. Scales pectinate, lateral shallow scales 57; lower lateral line scales larger than upper lateral line scales.
More than 2/3 of dorsal and anal fins are covered with small round scales. Lateral line curved anteriorly, straight posteriorly. Dorsal fins VIII-X31, beginning above the beginning of the pectoral fins. Anal fin II 9, beginning about opposite middle of dorsal fin rays, pectoral fin 15, beginning behind gill cover. Ventral fin smaller than pectoral. Caudal fin cuneate. Dorsal side of body grayish yellow, lower side golden yellow; dorsal and caudal fins grayish yellow, pectoral, ventral and anal fins yellow.
Mostly active in the middle and lower layers of seawater, with migratory habits.
2, small yellowtail, similar in shape to the large yellowtail but small. The body length is about 20 centimeters. Lateral line scales 60 to 63. dorsal fin IX 34 to 36, the beginning of the pectoral fin and the beginning of the opposite. Anal fin II 9, starting slightly behind the middle of the dorsal fin rays. Pectoral fin 19, long and pointed, ending beyond the end of the ventral fin. Ventral fin slightly shorter than pectoral fin. Caudal fin cuneate. Dorsal side of body grayish brown, sides and ventral side yellow, dorsal fin margin grayish brown. It has migratory habits.
