rich fishing ground are located on the pacific coast of north america. give reason
Answers
ANSWER:
Due to the convergence of warm and cold currents the Pacific coast of North America has rich fishing grounds .
EXPLANATION:
The Pacific coast of North America is affected by the warm Kuroshio currents (north-flowing warm ocean current on the west side of the north Pacific ocean) and cold Oyashio currents (cold current that flows via the Bering strait in southerly direction and transports the Artic sea’s cold water into the Pacific ocean) and is the famous fishing grounds of different species of fishes.
Due to the meeting of the warm and cold currents in this place, large amount of fog is generated which controls temperature conditions that is ideal for fishes. Currents are crucial in marine (fish) ecosystems since they re-distribute heat, water, oxygen and nutrients, about the ocean.
When cold and warm currents met, the regions have high biological productivity, since plankton, algae and other plants growth is encouraged by the blending of cold and warm currents.
Many of the globe’s most productive and rich fishing grounds are situated where cold and warm currents converge.
Answer:
Rich fishing ground are located on the pacific coast of North America due to convergence of the warm Kuroshio current and cold Oyashio current.
