Question

Why are continental shelves regarded as the best grounds for fishing?

• A. These are the most undisturbed zones in the ocean.
• B. The region has an abundance of algae and plankton which attracts a lot of fishes.
• C. The salinity of water makes laying nets easier.
• D. Fishes can only live in this zone of the ocean.

Answer 1

The correct option is B The region has an abundance of algae and plankton which attracts a lot of fishes.

The continental shelves across the world provide favourable conditions for fishes to thrive in. This zone is shallow, thus allowing the sunlight penetrate though it, facilitating the growth of algae and plankton. The algae and plankton are great sources of food for fishes, and so they are drawn to the continental shelf region.
