The most important fishing grounds of the world are found in the regions where warm and cold oceanic currents meet.

Here's why

Nutrient-rich waters When warm and cold currents converge, a process known as upwelling occurs. This upwelling brings nutrient-rich deep ocean water to the surface. These nutrients act like fertilizer for plankton, which forms the base of the marine food chain.

Abundant Marine Life The abundance of plankton attracts a vast array of fish species, making these areas highly productive fishing grounds. Examples include The Grand Banks (Newfoundland) - Labrador Current (cold) meets the Gulf Stream (warm) The Humboldt Current (South America) - cold, nutrient-rich current flowing up the western coast The Canary Current (West Africa) - cold, nutrient-rich current flowing up the western coast
