3.6.1. Breeding technique
Unit 3 - Breeding of major carps
- Induced breeding of carps starts with the onset of south-west monsoon, June.
- The male and female brooders are conditioned for a few hours prior to injection.
- Sets of brooders are formed, each consisting of 1 : 2 (female : male) ratio.
- The injected brooders are released in the breeding hapa.
Breeding hapa
- A Breeding hapa is a box-shaped cloth enclosure made of long cloth, generally of size 2 x 1 x 1 m with provision to close its top after releasing brooders.
- The upper flap is attached to one side and the other sides are either tied or buttoned.
- The hapa is fixed in a canal or pond or cement cistern.
-
The four bottom and four top corners are tied to four poles such that the bottom of the hapa should not touch the ground and one-third of the hapa remain above the water level.
