What are the advantages of becoming the largest fishing ground and saltworks?

The beach is flat, hot all year round, sunny, windy, with little rainfall, large evaporation and good salt drying conditions.

The key to the formation of fishing grounds is that two or more ocean currents meet here, some are warm and some are cold.

Such as the four major fishing grounds:

Judging from the influence of ocean currents on fishing grounds, there are four major fishing grounds in the world:

1, Hokkaido fishing ground is formed by the intersection of Japanese warm current and Thousand Island cold current.

2. Newfoundland fishing ground is formed by the confluence of Gulf Warm Current and Labrador Cold Current.

3. Beihai Fishing Ground is formed by the confluence of the North Atlantic warm current and the East Greenland cold current.

4. The fishing grounds in Peru are formed by the rising compensation current along the coast of Peru.

Considering comprehensively, marine fishery resources are mainly concentrated on the coastal continental shelf, that is, the part of the continental seabed extending from the coast to about 200 meters underwater. Here, the sunshine is concentrated, the photosynthesis of organisms is vigorous, and the rivers entering the sea bring rich nutrients, so plankton flourishes. They are the bait of fish, and are generally more in temperate waters. The seasonal changes in temperate waters are remarkable. In winter, surface seawater and bottom seawater are exchanged, and flooding seawater is rich in nutrients, which is beneficial to plankton reproduction. In addition, where cold and warm currents meet and cold seawater overflows, the bait is also very rich.

Therefore, there is a cold current in the North Pacific Ocean and a warm current in the equatorial waters off the east of China, which may form a fishing ground at the second intersection.
