Dr. Esther Wairimu

Dr. Esther Wairimu is a Research Scientist at Kenya Marine and Fisheries Research Institute (KMFRI). She has been working under marine aquaculture research division with an experience of more than 8 years. Her research interest covers; culture systems with specific interests in Integrated Multitrophic Aquaculture, fish nutrition, selective breeding, brood stock management, seed production, ornamental fish culture and population genetic studies on fish.

She is involved in on farm training of fish farmers and coastal community groups for technology transfer.

She has been involved in collaborative projects in the region and has been a project investigator of three donor funded projects one from Western Indian Ocean Marine Science Association (WIOMSA) investigating on fish nutrition for marine cultured fish and two from The National Research Fund (NRF) a research fund on seaweed farming methods and an innovation grant on seaweed value addition.

She is currently a co-investigator in two projects, The first is on undertaking research in validating and promoting Improved Fish Strains and Health Management Practices for Climate Smart Aquaculture in Western Kenya under the Kenya Climate Smart Agriculture Project (KCSAP) funding, 2020 -2022.

The second is by the Western Indian Ocean Marine Association (WIOMSA) MASMA programme to undertake a research on Blue Growth Initiative through Farming of Silver Pompano (Trachinotus Blochii) and Rabbit Fish (Siganus Sutor) for Food Security and Improved Livelihood in East Africa (BLUEGRASI), November 2020 - December 2022.


Esther has published 12 papers in peer reviewed journals, developed technical reports, policy briefs, and participated in regional and local seminars, workshops, conferences, and open days.
