question 1: where is Zhoushan fishing ground? That's a good question to ask. Well, if it's a geographical location, I think these friends have answered it in detail. The ocean near Zhoushan Archipelago (the northern part of the East China Sea and the southeast coast of the Yangtze River estuary are located outside the mouth of Qiantang River and the south of the Yangtze River estuary) is one of the four major fishing grounds in the world. The Zhoushan Archipelago is dominated by Dinghai and shenjiamen, surrounded by more than 1,111 small islands such as Daishan, Putuo Mountain, Zhujiajian Island and Taohua Island.

question 2: which river is the estuary of Zhoushan Fishing Ground? Zhoushan Fishing Ground is located outside the Qiantang River estuary, with a range of 29 31 @ ~ 31 11 @ n, 125 11 @ e and an area of about 14,351 square nautical miles.

question 3: in which sea area is Zhoushan fishing ground located, and how is Zhoushan fishing ground formed? Zhoushan fishing ground is located in the East China Sea east of Hangzhou Bay and southeast of the Yangtze River estuary, with latitude of 29 31 ′ ~ 31 11 ′ north latitude and longitude of 121 31 ′ ~ 125 11 ′ east longitude, covering an area of about 53,111 square kilometers. It is the largest fishing ground in China, and it is a traditional fishing area for fishermen in Zhejiang, Jiangsu, Fujian and Shanghai provinces, and in Taiwan Province.

Zhoushan fishing ground is located at the mouth of the Yangtze River, Qiantang River and Yongjiang River, where coastal current, Taiwan Province warm current and Yellow Sea cold water mass meet. The main reasons for the formation of fishing grounds are as follows: < P > The East China Sea has a vast continental shelf with sufficient light and nutrients;

Yangtze River water flows in, bringing a lot of nutrients;

Taiwan Province warm current and coastal cold current meet here, which makes the water flow stir and the nutrients float;

There are many surrounding islands, which provide favorable conditions for the life and reproduction of fish;

Proper placement is the only way for many economic fish to swim back;

The rising compensation current at the confluence of cold and warm ocean currents brings deep-sea nutrients;

Question 4: Where is Zhoushan Fishing Ground? Zhoushan Fishing Ground is located in the north of the East China Sea, southeast of the Yangtze River estuary, outside the Qiantang River estuary and south of the Yangtze River estuary fishing ground. Its range is: the sea area west of 29 31 @ ~ 31 11 @ n, 125 11 @ e, with an area of about 14,351 square nautical miles. It is the largest fishing ground in China.

question 5: where is Zhoushan fishing ground in the waters around Zhoushan city, Zhejiang province? Specifically, the northern part of the East China Sea and the offshore southeast of the Yangtze River estuary are located outside the Qiantang River estuary and south of the fishing ground of the Yangtze River estuary, with a range of 29 31 @ ~ 31 11 @ n, 125 11 @ e and an area of about 14,351 square nautical miles.

question 6: where is the largest fishing ground in China? Zhoushan Fishing Ground Zhoushan Fishing Ground is the largest fishing ground in China and one of the world-famous fishing grounds, covering an area of 116,111 square kilometers. The outer side is not only a vast fishing ground in the East China Sea, but also a relatively open marginal sea area in the Northwest Pacific Ocean, with a fishing ground on the continental shelf covering an area of 572,911 square kilometers.

Zhoushan fishing ground is the largest offshore fishing ground in China, which is as famous as Thousand Islands fishing ground in the Soviet Union, Newfoundland fishing ground in Canada and Peru fishing ground in Peru. Fishermen are used to dividing Zhoushan fishing ground into Dakun fishing ground, Shengshan fishing ground, Langgang fishing ground, Huang Ze fishing ground, Daiqu fishing ground, Zhongjieshan fishing ground, Yang 'an fishing ground and Jintang fishing ground according to each operation sea area.

Zhoushan Fishing Ground has been a fishing ground for coastal fishermen since its development. Since liberation, the number of fishing boats from Zhejiang, Jiangsu, Fujian and Shanghai (referred to as "three provinces and one city" for short) has been increasing, and some fishing boats from Liaoning, Hebei, Shandong, Tianjin and other provinces and cities have once come to Zhoushan Fishing Ground for fishing. During the 1961s and 1971s, fishing boats gathered in Shengshan Fishing Ground to catch hairtail in winter. At the peak of flood season, there were 11,111 fishing boats and more than 51,111 fishermen.

geographical location Zhoushan fishing ground is located at 29 3o' ~ 31 oo' north latitude and 121 3o' ~ 125 11' east longitude, with an area of about 53,111 square kilometers to the east, Yushan fishing ground to the south and Changjiang estuary fishing ground to the north. The seabed is mainly composed of fine-grained sedimentary mixtures such as silty ooze and clayey ooze, which is an integral part of the continental shelf of the East China Sea. The water depth is generally 21 ~ 41 meters. The 81-meter isobath from north to south is 281 ~ 151 kilometers wide from the shore.

Hydrological elements Zhoushan Fishing Ground is located at the mouth of Yangtze River, Qiantang River and Yongjiang River, where coastal current, Taiwan Province warm current and Yellow Sea cold water mass meet. On average, the Jingliu River in the mainland flows into the sea every year, reaching nearly 1 trillion cubic meters, forming a powerful 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 is hot and salty, and the water color is clear. It wedges from south to north in spring and summer, reaching the coastal waters, deviating from the coast in winter and retreating to the south. The Yellow Sea cold water mass moves southward. With the change of the intensity of the warm current in Taiwan Province, it extends into the fishing ground like the tip of the tongue in autumn and winter, and gradually retreats northward in early summer, forming a mixed zone of the north and south water masses. The tidal current of fishing ground belongs to the regular semidiurnal tidal area, and the outer islands connect with the east sea area, and the flow direction is clockwise, and the west sea area and islands are arranged, and the reciprocating flow is prominent. The water temperature of fishing ground is the highest monthly average of 28℃ ~ 29℃ in summer and below 8℃ in winter. The salinity of fishing ground is 29 ~ 34 ‰ in the outer sea area. The inner sea area changes greatly due to the influence of the continental current, which is low in summer and high in winter.

The continuous injection of biological resources from rivers and rivers in mainland China brings a large number of plankton to the fishing ground, which combines with seawater nutrients to promote its rapid growth and reproduction. The contents of phosphorus and silicon in offshore fishing grounds are 31 ~ 41mg/m3 and 2111 ~ 3111mg/m3 respectively. There are 151 species of phytoplankton in shallow waters, among which phytoplankton account for more than 91%. The annual average content of phytoplankton in water is 1.17× 1.14/m3, which is high in summer and low in winter. There are 123 species of zooplankton, with an average annual content of 87.7 mg/m3, and the highest in summer is 1.633 mg/m3.

The superior natural conditions such as geography, hydrology and biology make Zhoushan Fishing Ground and its adjacent waters a living habitat suitable for breeding, growth, feeding and wintering of many kinds of fish. Among them, Pseudosciaena crocea, Pseudosciaena crocea, hairtail and squid are the resource groups with the largest catch in Zhoushan fishing ground, which are called "four major fish production".

The main fishing season started from the end of 1971s, with small yellow croaker in spring, large yellow croaker and squid in summer, jellyfish in autumn and fish in winter. With a large number of motor boats put into production all the year round, there is no obvious boundary in the fishing season. Since the 1981s, small yellow croaker, large yellow croaker, cuttlefish and jellyfish have failed to form a fishing season, and the fishing season with fish also appears to be not prosperous and the net production tends to be low.
