Question

Harpadon nehereus forms a major single species along coast of

• A. Northwest
• B. Southwest
• C. Southeast
• D. Northeast

Hint:

Bombay Duck Fisheries: Harpadon nehereus $\rightarrow$ NORTHWEST COAST (Gujarat & Maharashtra, $> 90\%$ catch) harvested by DOL NETS (Bag nets).

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Marine fisheries resource distribution in India: Harpadon nehereus (Bombay duck) exhibits a discontinuous distribution forming a massive commercial fishery along the Northwest coast of India.

Step 2: Detailed Explanation:
In Indian marine fisheries (CMFRI resource distribution):
- {Harpadon nehereus (Family Synodontidae Harpadontidae), commonly known as 'Bombay Duck' (Lote/Bombil):
- Shows a unique, classic discontinuous geographic distribution along the Indian coastline.
- Over 90% of the commercial landings of Bombay duck occur along the Northwest Coast of India (Maharashtra and Gujarat), where tidal amplitudes are exceptionally large (up to $10 - 12\text{ m}$), enabling traditional commercial bag-net (Dol Net) fishing operations in the Gulf of Cambay and coastal waters.

Step 3: Final Answer:
Thus, Harpadon nehereus forms a major fishery along the Northwest coast, corresponding to option (A).
