Question

Match List I with List II
List I: A. Seasoning, B. Light fishing, C. Electric fishing, D. Line fishing
List II: I. Galvanotaxis, II. Bait, III. Fish attraction, IV. Timber
Choose the correct answer from the options given below:

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

Hint:

Galvanotaxis is the "forced swimming" toward the positive electrode (anode) in electric fishing. It is highly efficient for sampling in small freshwater streams.

Answer 1

The Correct Option is D

Step 1: Understanding the Question:
The question connects different fishing-related processes or methods with their underlying technical principles or materials.

Step 2: Detailed Explanation:

• A - Seasoning: In the context of fishing boat construction, seasoning refers to the controlled drying of Timber (IV) to reduce moisture content and increase durability against rotting and warping in marine environments.

• B - Light fishing: This method involves using artificial light sources at night. The light acts as a stimulus for Fish attraction (III), as many pelagic species are phototactic and gather around the light source.

• C - Electric fishing: This is a specialized fishing technique that uses an electric field in water. The electric current induces an involuntary movement in the fish called Galvanotaxis (I), causing them to swim toward the anode where they can be easily collected.

• D - Line fishing: This traditional method (hooks and lines) relies on deceiving the fish into biting a hook. This is achieved using a Bait (II), which can be natural (food) or artificial (lures).

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

Step 3: Final Answer:
The correct match is A-IV, B-III, C-I, D-II.
