From the perspective of the impact of ocean currents on fishing grounds, there are four major fishing grounds in the world:

1. Hokkaido Fishing Ground: It is formed by the intersection of the Japanese warm current and the cold current of Thousand Islands.

2. Newfoundland Fishing Ground: It is formed by the intersection of the Gulf of Mexico warm current and the Labrador cold current. Once one of the four largest fishing grounds in the world, but after centuries of wanton fishing, especially after the large mechanized trawlers began to operate in the fishing grounds in the 1950s and 1960s, the Newfoundland fishing grounds gradually disappeared. visible. The Newfoundland fishing grounds are now history.

3. The North Sea fishing ground: It is formed by the intersection of the North Atlantic warm current and the cold water southward of the Arctic Ocean (Eastern Greenland cold current).
4. Peru fishing grounds: It is formed by the rising compensation current of the Peruvian cold current, which causes the deep seawater to rise.

Comprehensively considered, marine fishery resources are mainly concentrated in the coastal continental shelf, that is, the part of the continental bottom extending from the coast to the depth of about 200 meters underwater. Here the sunlight is concentrated, the biological photosynthesis is strong, and the rivers entering the sea bring rich nutrients, so the plankton is prosperous. They are bait for fish, generally in temperate sea areas.

Seasonal changes in temperate sea areas are significant. In winter, surface seawater and bottom seawater are exchanged. The flooded seawater is rich in nutrients, which is beneficial to plankton reproduction.

In addition, the cold and warm currents converge and the cold seawater floods, and the bait is also very rich.
Considering these aspects comprehensively, there are five major fishing grounds in the world:

1. North Pacific fishing grounds: It is a vast area including Hokkaido fishing grounds, my country's Zhoushan fishing grounds, and many fishing grounds on the west coast of North America;

2. Southeastern Pacific Fisheries: It is a vast area including Peruvian fisheries;

3. Northwest Atlantic Fishing Ground: It is a vast area including Newfoundland Fishing Ground;

4. Northeast Atlantic Fishing Ground: It is a vast area including the North Sea Fishing Ground;

5. Southeast Atlantic fishing ground: It is a vast area including coastal fishing grounds in southwestern Africa
