Shrimp and prawn farming are important aquaculture activities in:

Coastal Tamil Nadu
Hilly regions
River deltas
Urban areas

The correct answer is: a) Coastal Tamil Nadu.

Shrimp and prawn farming are important aquaculture activities in coastal areas because these areas have the necessary conditions for shrimp and prawn farming, such as:

  • Abundant water supply
  • Suitable climate
  • Suitable soil
  • Access to markets

Coastal Tamil Nadu has all of these conditions, which is why it is a major shrimp and prawn farming region.

Hilly regions do not have the necessary conditions for shrimp and prawn farming, such as abundant water supply and suitable climate. River deltas do have the necessary conditions for shrimp and prawn farming, but they are not as important as coastal areas for this activity. Urban areas do not have the necessary conditions for shrimp and prawn farming.
