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): Associated with destruction of mangroves (III), as ponds are often created by clearing mangrove forests.
• Inland Pond (B): Leads to degradation of land (IV), as constructing ponds can result in soil erosion and salinization.
• Mollusk Culture (C): Can cause the introduction of exotic species (II), due to the importation of non-native mollusks for aquaculture.
• Net Pen/Cage (D): Results in transfer of diseases (I), as dense fish populations in cages facilitate the spread of pathogens.
