Show answer
Answer: C. Warm and cold oceanic currents meet
Analysis
The world's major fishing grounds are generally located in regions where warm and cold ocean currents meet. The mixing of these currents creates ideal conditions for the growth of plankton, which are microscopic marine organisms forming the base of the aquatic food chain.
The abundance of plankton attracts large numbers of fish, making such areas highly productive fishing zones.
Examples include:
- Grand Banks near Newfoundland
- Coastal regions of Japan where the Kuroshio and Oyashio currents meet
Extra UPSC info
Cold currents are usually nutrient-rich because they bring nutrients from deeper ocean layers to the surface through upwelling, increasing marine productivity.
