Question

6) State four advantages of induced breeding

Answer 1

The artificial process by means of which the extract of the pituitary is introduced inside the body of both the matured male and fishes, then carps after being excited lay eggs in the pond water and subsequently fertilization takes place and the process is called induced breeding of fishes. This process of breeding is also known as hypophysation. The advantages are:-

1)Eggs and spawns of carps at the collected from the river bed, there is no possibility of mixture of other fishes of eggs and spawns. Whereas, in the induced breeding there is no possibility of mixture and as a result the pure form of fish sees are obtained.
2)Desired species of carps can be cultured through the induced breeding.
3)large numbers of eggs are available from a fish through induced breeding.
4)In same season, a carp can be induced to breed more than once.
5)Transportation cost becomes very low as the carps can breed in any desired pond.
6)Between the different species of fishes hybridization can be done and it is possible to get hybrid variety of fishes.

Answer 2

Answer:

• A number of environmental factors, including temperature, pH, rain, photoperiod, inadequate hormone release, and nutrition availability, lead to induced breeding.
• One of the reliable methods for supplying high-quality seeds is induced breeding, which involves injecting pituitary hormones into ponds to encourage the reproduction of large carps. Pituitary extract is frequently used to encourage fish to reproduce in several nations.
• Economically significant fish that are incapable of reproducing under certain circumstances can do so under artificial conditions known as induced breeding. When compared to the expense of using natural resources, the cost of producing seeds by forced breeding is quite low.
• Induced breeding, which is a synthetic process in which the pituitary gland is removed from mature fish or donor fish and implanted into the bodies of male and female fish, is therefore highly successful in pisciculture. As a result, fish deposit eggs in the pond water, and fertilization occurs.
