Anterior gill cover with smooth margins, posterior margin of gill cover with a flattened blunt spine. Gill pores very short, about 6 times as long as eye diameter.

The body is covered with thin, weak pectinate scales, and the head is covered with scales except for the interocular septum, the anterior gill cover bones, and the muzzle. Dorsal and anal fin spines with well-developed scale sheaths, fin bases scaly, lateral line complete, arcuate.

The yellowfin seabream does not have long-distance migratory habits, but has obvious reproductive migration behavior. About two months before spawning, it moves from the nearshore or living in brackish and freshwater waters to the deeper zone of high salt, a process that takes about two months, and then returns to the nearshore after spawning. It is widely distributed in the Red Sea, Arabian Sea, India, Indonesia, Korea, South Korea, Japan (Honshu, Shikoku, and Kyushu), Philippines, Australia, and the southeastern coastal waters of China.

1, wild yellow finfish pectoral fins, ventral fins and anal fins in the body of the fish will be fresh fresh yellow, yellow finfish caught offshore will be bright pinkish-yellow, yellow finfish farmed these fins due to the relationship between the quality of the aquaculture waters will be presented with the earthy yellow, not so bright;

2, the tail tail shank part of the yellow finfish wild yellow finfish and yellow finfish farmed compared to the fish body Slender, the tail stalk is also longer, which is its life in the natural environment, the tide changes, the sea is different, the fish's ability to move is not the same, farmed yellowfin fish by the breeding net box restrictions, the activities of the region is small, not how to withstand the impact of the tide, the fish body is relatively more rounded, the fish tail stalk is also shorter;

3, bought back the yellowfin fish to kill the time can be seen whether the wild or farmed, the farmed fish belly There is usually a thick layer of grease in the belly of the farmed fish, and the food supply of wild yellow fins is not regular and guaranteed, so there is usually not a very thick layer of grease.

4, wild yellowfin fish taste delicious, meat tough enough, farmed yellowfin fish taste sandy flavor, meat loose;

5, there are vendors on the market will be cheaper "head" as wild yellowfin fish, "head" of the head is rounded, yellowfin is pointed.
