Artificial reproduction of Koi carp in Vietnam (Video)

The inserted video was filmed in a private fish hatchery in Vietnam. The video began with the egg stripping upon the ovulation of two females. One can notice that the egg volume varied among the two females with much more eggs in the second female compared to the first one. The video shows the gentle pressing on the female’s body and eggs stop free flowing, the female was considered a spent and was taken to a recovery pond. The two batches of eggs were mixed and dry-fertilized by the sperm directly stripped from one male. As shown in the video, a bird feather is used for the gentle mixing of eggs with the sperm. Typically, after the water-hardening of eggs, they will be incubated until hatching.
