life habit

During the growth, development and fattening period, the bonito, which is distributed in China's offshore waters, mostly lives in the bottom of the sea where the water quality is turbid, and belongs to the shallow sea bottom fish. The bonito does not integrate into large groups in the ocean, but mostly scatters in the bottom of the coastal and nearby waters, and belongs to the offshore benthic fish. Entering the vicinity of the Yangtze River estuary, large groups gradually integrated, rising from the bottom to the middle and upper layers, mostly inhabiting in turbid waters, but less in clear water.

Stop feeding during reproductive migration. It is widely distributed in the middle and lower reaches of the Yangtze River, from the Yangtze River estuary to Dongting Lake, including rivers and lakes in Tongjiang. Some bonito can enter Qiantang River in early spring and trace back to Tonglu area, but the number is small, mainly distributed in the offshore. They not only overwinter in the bottom of the nearby waters, but also enter the shallows and bays with less wind and waves on the island shore and feed.
