Question

Match List I with List II

Choose the correct answer from the options given below:

• A. A - II, B - III, C - IV, D - I
• B. A - II, B - IV, C - III, D - I
• C. A - III, B - II, C - IV, D - I
• D. A - III, B - IV, C - I, D - II

Hint:

Bhattacharya method = cohort separation (using logarithmic differences of frequency).
Jones' Method = Length-based cohort analysis.
Beverton & Holt = Yield per recruit.
Memorizing these combinations is highly useful for stock assessment exams.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Various mathematical models and graphical methods have been developed in fish stock assessment to analyze size frequencies and estimate yield.

Step 2: Detailed Explanation:
Let us match the scientific methods with their authors:
- A. Bhattacharya (1967): Developed a famous graphical method for the Separation of cohorts (II) from a mixed length-frequency distribution.
- B. Alagaraja (1984): Proposed the Relative response model (III) for stock assessment.
- C. Beverton and Holt (1956): Formulated the classic Yield per recruit model (IV) (analytical model).
- D. Jones (1984): Developed the Length-based cohort analysis (I) (or Jones' Length Cohort Analysis, LCA).
The correct matching is: A - II, B - III, C - IV, D - I.

Step 3: Final Answer:
This matches option (A).
