Question

Match List I with List II:

LIST I (Aquaculture system)	LIST II (Potential Environmental Impact)
A. Coastal Pond	I. Transfer of diseases
B. Inland Pond	II. Introduction of exotic species
C. Mollusk Culture	III. Destruction of mangroves
D. Net Pen/Cage	IV. Degradation of land

Choose the correct answer from the options given below:

• (A) - (III), (B) - (II), (C) - (IV), (D) - (I)
• (A) - (I), (B) - (IV), (C) - (III), (D) - (II)
• (A) - (III), (B) - (IV), (C) - (II), (D) - (I)
• (A) - (IV), (B) - (I), (C) - (II), (D) - (III)

Hint:

Aquaculture impacts vary: coastal ponds often destroy mangroves, inland ponds degrade land, mollusk cultures may introduce exotic species, and net pens/cages can transfer diseases.

Answer 1

The Correct Option is C

• Coastal Pond (A): Linked to mangrove destruction (III), stemming from the clearing of mangrove forests for pond establishment.
• Inland Pond (B): Causes land degradation (IV), notably through soil erosion and salinization during construction.
• Mollusk Culture (C): May prompt the introduction of exotic species (II), originating from the import of non-native mollusks for aquaculture.
• Net Pen/Cage (D): Leads to disease transfer (I), as high fish densities in cages accelerate pathogen dissemination.
