Living habits:

The warm pelagic fish in the offshore mainly inhabit the shallow continental shelf, sometimes appear on steep slopes or lagoons, and even in estuary waters. I like living in coastal areas and waters where coastal water meets external seawater. Fierce sex, strong swimming ability, like clustering. The phenomenon of vertical movement day and night is obvious. The weather is clear, the tide is slow, the morning light is weak or it is raining in Mao Mao, and fog often floats on the water and jumps out of the water. When the water temperature is low, it often sinks into the middle water. The wintering ground is located at the water depth of 80~ 100 m from the southeast of the Yellow Sea to Wudao, 80~ 150 m from the south-central part of the East China Sea to the north of Diaoyu Island, and from the south of the East China Sea to the north of the South China Sea.

At the end of winter and the beginning of spring, the fish gradually moved away from the wintering ground for breeding and migration. The main food is small fish such as dike fish and shrimp. Male 1 year-old, female 2 years old, all reached maturity. The breeding period is from May to July.
