The breeding season of carps is mainly the rainy season. But in the rainy season the fish breeding is never occur in confined water of pond. But it is possible to breed them even in the confined pond water through two processes such as Bundh breading and Induced breeding. Now let us have some discussion about the above two types of fish breeding.
In this process, the rain water that rolls along the gradual slopping of the high altitude is collected and retained at the base of the sloping by making an earthen wall. The shallow water inside the earthen wall or bundh acts as a breeding place of carp fishes. This technique is known as the Bundh Breeding. The bundh may be of two types, namely the wet bundh and the dry bundh.
What is wet bundh?
The wet bundh consist of two parts, such as ponds and a bundh. The pond that contains water throughout the year is just situated at the base of the hill sloping. So, it is acting as the stocking pond. Surrounding the pond an earthen bundh is constructed on the three sides except on the sloping side of the hill and the sloping side remain open. On the opposite end of the sloping side there is an opening on the bundh which is connected with a tunnel known as bulan. The opening of the bulan remains closed by generally a bamboo made sheet. Through this bamboo sheet only the excess water of the bundh goes out but the fishes cannot go out. The adult carps both female and male are present in the stocking pond. When the monsoon come, the rain water rolls very rapidly along with the sloping of the hill comes down to the bundh. As a result the stocking pond is also over flooded and the fishes migrate to the shallow water of the bundh. This shallow water of the bundh acts as a breeding place of the carps and fish breeding takes place.
What is dry bundh?
There is no stocking pond in the dry bundh as it is in wet bundh. Only the rain water which comes during the monsoons with heavy speed along with the sloping is collected and stored inside the bundh and the bundh is made up mud on three sides. The sloping side remain open as well. The mature male and female carps are released during the rainy season inside the bundh and the fish breeding takes place.
Process of fish breeding and hatching:
When the monsoons come, the rain water comes along the sloping roles into the bundh and than the matured carps of both female and male is excited. After the excitation, the female fish then lays eggs in the shallow water of the bundh and the eggs are fertilized externally by males. This shallow place of bundh where the female fish lays eggs is known as Moan. Then the eggs are collected by a net and are transferred in a more secured area inside a hatching hapa. After two hours of fertilization the spawns are developed from the eggs. Then the spawns come out to the outer hapa from the inner heap. The spawns are allowed to stay in the outer hapa for three days. After that they are transferred to the nursery pond and the fish breeding process by bundh breeding is completed.
