World Fishing Grounds and Ocean Currents

The world's most important fishing grounds are located where warm and cold oceanic currents meet. This occurs because the convergence of these currents creates areas of upwelling and nutrient enrichment. Cold currents bring nutrient-rich water from the depths to the surface, while warm currents carry abundant plankton. The mixture of these currents creates ideal conditions for fish spawning and feeding. Examples include the Grand Banks off Newfoundland (where the cold Labrador Current meets the warm Gulf Stream) and the waters off Japan (where the cold Oyashio meets the warm Kuroshio Current). Option (b) is also important but not the primary reason. > Fishing Grounds Rule: Where warm and cold ocean currents Converge, nutrient upwelling creates rich fish populations and the world's best fishing zones. Answer: (c).
