Question

Given below are two statements
Statement I: There exists a high co-relation between dietary amino acid requirements of fish and body compositions of amino acids
Statement II: Research data obtained suggest that essential amino acid requirements of Catla, Rohu and Mrigal do not vary much
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:

All fish species require the same 10 essential amino acids (arginine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine). Their quantitative requirements can be estimated by matching the feed composition with their muscle tissue profile.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Formulating balanced feeds for aquaculture requires precise quantification of essential amino acid (EAA) profiles to maximize muscle deposition and minimize nitrogen excretion.

Step 2: Detailed Explanation:
- Statement I: There is a well-established and highly significant correlation between the quantitative dietary essential amino acid requirements of a fish and the amino acid profile of its whole-body tissue (known as the A/E ratio or tissue-profile matching method).
This biological relationship is used by nutritionists to formulate balanced diets.
Hence, Statement I is correct.
- Statement II: Extensive nutritional research on Indian Major Carps (Catla, Rohu, and Mrigal) has revealed that their quantitative requirements for the 10 essential amino acids are highly similar, showing only minor, negligible differences.
Hence, Statement II is correct.

Step 3: Final Answer:
Both Statement I and Statement II are correct, which corresponds to option (A).
