Question

Selective breeding technique was followed while developing

• A. Super male tilapia
• B. Super salmon
• C. Jayanthi rohu
• D. Catla-rohu hybrid

Hint:

CIFA's Pride: Jayanthi Rohu.
Method: Selective Breeding.
Benefit: ~17% higher growth rate per generation.
It is the Indian equivalent of the international GIFT Tilapia project.

Answer 1

The Correct Option is C

Step 1: Understanding the Question:
The question requires identifying which of the listed fish strains was specifically developed using selective breeding techniques in India.
Detailed Explanation:

• Jayanthi Rohu: This is the first genetically improved fish strain in India, developed by ICAR-CIFA (Bhubaneswar) in collaboration with AKVAFORSK (Norway). It was officially released in 19

• Technique: It was developed through a multigenerational selective breeding program (family-based selection) starting from founder stocks collected from five major rivers of India. The primary objective was to improve the growth rate and disease resistance of Rohu (Labeo rohita).

• Other Options:
• Super male tilapia: Produced through hormone treatment and progeny testing (Genetic sex determination).

• Super salmon: Usually refers to Transgenic (GMO) salmon (e.g., AquAdvantage).

• Catla-rohu hybrid: Produced through intergeneric hybridization, not selective breeding of a single species.

Step 3: Final Answer:
Jayanthi rohu was developed through selective breeding.
