Question

Given below are two statements, one is labelled as Assertion A and the other is labelled as Reason R
Assertion A: In the Indian freshwater aquaculture Catla is a predominantly farmed fish
Reason R: Catla do not have great export overseas market
In light of the above statements, choose the most appropriate answer from the options given below

• A. Both A and R are correct and R is the correct explanation of A
• B. Both A and R are correct but R is NOT the correct explanation of A
• C. A is correct but R is not correct
• D. A is not correct but R is correct

Hint:

Always check if the "Reason" represents the actual cause of the "Assertion" by adding "because" between them.
"Catla is predominantly farmed *because* it does not have a great export market." This statement is logically incorrect.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
Evaluating species choice in regional aquaculture requires analyzing biological suitability alongside local and international market economics.

Step 2: Detailed Explanation:
- Assertion A: Catla (Labeo catla) is indeed a predominantly farmed freshwater fish in India, acting as the surface feeder in the classic Indian Major Carp polyculture.
Hence, Assertion A is correct.
- Reason R: Catla is mostly consumed domestically within the South Asian region and does not possess a large, highly lucrative international export market compared to species like shrimp, salmon, or tilapia.
Hence, Reason R is correct.
- Is R the correct explanation of A? No, Catla is predominantly farmed in India because of its exceptionally rapid growth rate, efficient utilization of surface plankton, and high domestic consumer demand, not because it lacks an export market.

Step 3: Final Answer:
Both A and R are correct but R is NOT the correct explanation of A, which corresponds to option (B).
