Jacob Abwao

Jacob Abwao is a research scientist based in Sagana aquaculture centre. I have had over 10 years of experience in areas of fish nutrition and fish breeding. Through my job engagement, I have interacted with fish farmers through training.  Am currently leading a team of scientists on selective breeding of both the catfish and Nile tilapia in Sagana centre.  This is one of the activities of the Kenya climate smart Agriculture project. Am also spearheading the domestication of indigenous species like Labeo victorianusOreochromis jipe and tilapia baringoensis. My other research study is on the feasibility of cage culture in the ASAL focusing on the community around the seven folks dams in Embu and Machakos counties. I have performed socio economic studies on the role of women in the cage culture value chain in Homabay County. As part of my doctorate studies am doing assessment of genetic diversity and structure of Nile tilapia, O. niloticus in Kenya for optimization of aquaculture and conservation. I do supervise students on attachment and train farmers and hatchery managers on the good aquaculture practices.  I was involved in proposal development of the Kenya climate smart Agriculture project, which has been awarded.
