Question

In the induced breeding of Indian major carps, which of the following statements are correct?
(A). Pituitary glands are preferred over Ovaprim.
(B). Ovaprim is ready to use liquid form available in 10 ml vial, has consistency and given reliable results.
(C). Ovatide is an indigenous, cost effective hormonal formulation.
(D). GnRH is a steroidal hormone belongs to class of substances called peptides.
Choose the correct answer from the options given below:

• A. (A), (B), (C), (D)
• B. (A) and (B) only
• C. (C) and (D) only
• D. (B) and (C) only

Hint:

Ovaprim = Canadian/Imported. Ovatide = Indian/Indigenous. GnRH is a peptide (protein-like), NOT a steroid (fat-like). This is a common biological distinction tested in exams.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
Induced breeding involves the use of external hormonal stimuli to trigger ovulation and spawning in fishes that do not breed naturally in stagnant pond environments.
Detailed Explanation:
Statement (A): Incorrect. Synthetic hormones like Ovaprim are now generally preferred over crude pituitary extracts because pituitary glands vary in potency and carry a risk of disease transmission.
Statement (B): Correct. Ovaprim (salmon GnRH analogue + Domperidone) is sold as a ready-to-use liquid in 10 ml vials. It is highly consistent in its hormonal concentration.
Statement (C): Correct. Ovatide is an indigenous (Indian) synthetic hormone produced by Hemmo Pharma. It is similar to Ovaprim but more cost-effective for Indian farmers.
Statement (D): Incorrect. GnRH (Gonadotropin Releasing Hormone) is a peptide hormone, but it is not a steroidal hormone. Steroid hormones (like estrogen or testosterone) have a lipid base, while GnRH is a chain of amino acids.
Thus, only (B) and (C) are correct.

Step 2: Final Answer:
(B) and (C) only is the correct answer.
