Distribution of hairtail

Hairtail is widely distributed, mainly in the western Pacific and Indian Ocean. It can be seen in all coastal provinces of China and can be divided into two categories: north and south. Northern hairtail is larger than southern hairtail. It overwinters in the south of the Yellow Sea. In spring, it swims to Bohai Sea to form spring fishing season. In autumn, it forms a group and returns to the wintering place to form autumn fishing season. Southern hairtail moves north-south along the western edge of the East China Sea every year with different seasons. In spring, it migrates northward for reproduction and winters southward in winter. Hairtail in the East China Sea has spring and winter seasons.

Life Habits of Hairtail

Hairtail swimming ability is poor, floating in the middle of the sea during the day, down to the bottom at night, static head upward, the body was vertical, only by dorsal fin and pectoral fin waving, eyes watching the movement of the head, if found prey, dorsal fin on the rapid vibration, body bending, pouncing on food. Hairtail has the characteristics of queuing in groups. When the water temperature rises every spring, hairtail groups swim to the shore, from south to north in reproductive migration, which is the fishing season. When the winter solstice, the water temperature decreases and swims to the depth of the water to avoid cold.
