Question

Given below are two statements:
Statement (I): African catfish is a fast growing one and recommended for culture in India.
Statement (II): Pangasius catfish is a suitable species for freshwater aquaculture.
In light of the above statements, choose the most appropriate answer from the options given below.

• A. Both Statement (I) and Statement (II) are correct.
• B. Both Statement (I) and Statement (II) are incorrect.
• C. Statement (I) is correct but Statement (II) is incorrect.
• D. Statement (I) is incorrect but Statement (II) is correct.

Hint:

Be careful with the word "Recommended." Just because a fish is grown everywhere (like African catfish) doesn't mean it is legally recommended or permitted.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
Aquaculture species are regulated based on their impact on native biodiversity. While some species grow fast, they might be ecologically harmful.
Detailed Explanation:
Analysis of Statement (I): The African catfish (Clarias gariepinus) is indeed extremely fast-growing. However, it is an invasive species in India. It is a voracious predator that threatens native fish populations. Consequently, its culture is banned or strictly prohibited by the Government of India (National Committee on Introduction of Exotic Species). Only the indigenous catfish Clarias batrachus (Magur) is recommended. Thus, the part of the statement saying it is "recommended" is incorrect.
Analysis of Statement (II): Pangasianodon hypophthalmus (Sutchi catfish) is a highly suitable species for freshwater aquaculture. It has been legally introduced and is widely cultured in cages and ponds across India (especially Andhra Pradesh) due to its high growth rate, acceptance of pelleted feed, and tolerance of high stocking densities. Thus, Statement (II) is correct.

Step 2: Final Answer:
Statement (I) is incorrect, but Statement (II) is correct.
