Dr. Paul Orina

Dr. Paul Sagwe Orina, a top KMFRI scientist, is based in Kegati Station, Aquaculture Division, and specializes in Freshwater Fish Breeding and Culture Systems. He holds a BSc in Zoology from the University of Eastern Africa, Baraton (Kenya), an MSc in Zoology from Moi University (Kenya), and a PhD in Animal Ecology from University of Eldoret also in Kenya. Dr. Orina is currently involved in breeding of indigenous species to assess their culture potential and inducting
the aquaculture value chain actors with commercialization concept through technology in line with the Blue Economy and Sustainable Development Goals (SDGs).
