3.6.1.b. Spawning
Unit 3 - Breeding of major carps
- After releasing the brooders in the hapa, they should not be disturbed.
- After about 6 hours, splashing will commence for breeding and be involved in courtship which will continue for one hour.
- At the climax of the courtship, both the partners will be seen in an embrace with their bodies twisted around each other. This exerts pressure on the abdomen, resulting the extrusion of gametes.
- The following morning, the spent brooders are removed and then the eggs are collected and transferred for hatching in a suitable hatching device.
