The Correct Option is C

Solution and Explanation

Step 1: Understanding the Concept:
Indian Major Carps (IMCs) represent the most crucial and dominant group of freshwater culturable fishes in India.
They comprise specifically three native species that share similar breeding habits, high growth rates, and compatibility under composite fish culture.

Step 2: Detailed Explanation:

The primary Indian Major Carps are:
1. Catla catla (Catla) - a fast-growing surface feeder.
2. Labeo rohita (Rohu) - a column feeder.
3. Cirrhinus mrigala (Mrigal) - a bottom feeder.
In contrast, Labeo gonius (commonly known as the Kuria labeo or Gooni) is categorized as a minor carp.
Minor carps have comparatively slower growth rates and do not attain sizes as large as major carps, making them distinct from the IMC group.

Step 3: Final Answer:

Therefore, Labeo gonius is not an Indian Major Carp.
