Question

Induced breeding (hypophysation) is carried out in case of
A. Pisciculture
B. Apiculture
C. Sericulture
D. Lac culture

Answer 1

Hint: Induced breeding of hypophysation is a breeding technology in which the organisms are bred artificially. This is done by injecting the animals with synthetic or the extracted pituitary hormones. Induced breeding is done generally to increase the organisms’ captivity.

Complete answer:
The technique of induced breeding is used to artificially breed the fishes. Therefore, it is used in pisciculture. Induced breeding stimulates the timely increase of the male and the female gametes, i.e., the sperms and the eggs from their respective gonads. Induced breeding is needed due to environmental conditions like rains, photoperiods, temperature, the insufficient release of hormones, and the unavailability of food naturally.
Induced breeding gives pure spawns of certain species of fishes under cultivation. This is because the spawns that are collected from the natural water sources are not very pure. Some wild and undesirable species always occur with them. Due to this reason, it becomes necessary to breed fishes using hypophysation.
Thus, based on the above information we can conclude that Induced breeding hypophysation) is carried out in the case of Pisciculture.
Hence, the correct answer is option (A).

Note: The technique of Induced breeding is very simple and cost-effective and it can fulfill the demand at any time. In the hypophysation technique, pituitary glands are located in the fishes. They are then removed and preserved in alcohol or acetone. After this, healthy and ripe brooders are selected who have two to four years of age and one to five kilograms of body weights. They are injected with the synthetic or extracted pituitary hormones by hypodermic syringe either intraperitoneal or infra muscular.
