Reproduction of rainbow trout (Oncorhynchus mykiss) in Kenya (Egg stripping and fertilization)

Striping eggs from a gravid female: The  stripping of the female is done under experienced hands of the hatchery  personnel at the Kibaru trout hatchery on the slopes of Mount Kenya, Kenya.

Egg fertilization: The second photo shows the  mixing of the sperm from a male brooder with the previously stripped eggs.

Rainbow trout, Oncorhynchus mykiss, is a cold water species that tolerates optimal tempertures of 15o Centigrade and below. Water used in the hatchery should be constantly flowing, well oxygenated  and crystal clear.

Note: We decided not to watermark the photos in order not to upset its clarity. However, we trust you will notify us if you wish to use a picture or more. This is expected and will be appreciated.
