Question

The scientist/s who developed the hypophysation technique for breeding of Indian major carps for the first time in India ?

• A. S L Hora
• B. Alikunhi K H and H Choudhri
• C. T V R Pillay
• D. V G Jhingran

Hint:

Date of first success: July 10, 1957. Scientists: Chaudhuri and Alikunhi. This date is celebrated annually in India as "National Fish Farmers Day."

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
Hypophysation is the technique of injecting fish with pituitary gland extract (hypophysis) to induce spawning. This was a revolutionary milestone for Indian aquaculture.
Detailed Explanation:
While the concept of using pituitary glands for breeding was initiated globally earlier, in India, the breakthrough success for Indian Major Carps (IMC) was achieved in 10th July 1957.
The primary scientists responsible for this development were Hiralal Chaudhuri and K.H. Alikunhi at the Pond Culture Division of the Central Inland Fisheries Research Institute (CIFRI) in Cuttack (now CIFA). They successfully bred Cirrhinus mrigala and Labeo rohita using carp pituitary extracts. This achievement allowed for a reliable supply of pure fish seed, ending the dependence on riverine seed collection.
1. S.L. Hora: Known for the Satpura Hypothesis regarding fish distribution.
2. T.V.R. Pillay: A pioneer in international aquaculture and brackishwater fisheries.
3. V.G. Jhingran: Author of the seminal book "Fish and Fisheries of India."

Step 2: Final Answer:
Alikunhi K.H. and H. Chaudhri are the correct scientists.
