Extended data

Zhoushan Fishing Ground is located at the mouth of the Yangtze River, Qiantang River and Yongjiang River, where the coastal current meets the warm current of Taiwan Province Province. The average annual runoff from the mainland into the sea is nearly 1 trillion cubic meters, forming a strong and low salt water mass with turbid water color, extending outward in spring and summer and retreating to the coast in autumn and winter.

The warm current in Taiwan Province Province is hot and salty, and the water is clear. Wedge from south to north in spring and summer, reaching the coastal waters, deviating from the coast in winter and retreating to the south. Along the coast, it flows south. With the change of warm current intensity in Taiwan Province Province, it extends into the fishing ground like the tip of the tongue in autumn and winter, and gradually retreats to the north in early summer, forming a mixed zone of north and south water masses. The tidal current of fishing ground belongs to the regular semidiurnal tidal area, and the peripheral islands are connected with the eastern sea area, and the flow direction is clockwise. The western sea area and islands are arranged, and the reciprocating flow is prominent.

The average monthly water temperature in fishing ground is 28℃ ~ 29℃ in summer and below 8℃ in winter. The salinity of fishing grounds in the outer sea area is 29 ~ 34 ‰. Due to the influence of continental runoff, the inland sea area changes greatly, which is low in summer and high in winter.
