Robert Ondiba
Mr. Ondiba a KMFRI Research Officer in Aquaculture Division has a focus in Fish nutrition; fish feed technology and water quality dynamics in different aquaculture systems. Earlier, Mr. Ondiba worked in the Lake Baringo ecosystem and the surrounding water bodies with special interest in water quality and the ecology of aquatic plants. While serving at Lake Baringo, Robert got an opportunity to work as a co-invesigator in a GEF funded cage culture project. While undertaking MSc thesis project, Mr. Ondiba was a Principal investigator in a NACOSTI funded project on use of Prosopis juliflora seeds as fish feed ingredient for replacement of cotton seed in Nile tilapia diet. Further, Mr. Ondiba has been involved in a number of on-station and on-farm aquaculture projects. For instance, he worked in the position of a co-investigator in a DSM collaborative project focusing on impacts of enriching Nile tilapia diets with a DSM additive and binder on performance.  Ondiba through GoK funded projects has been a principal investigator in the following 4 projects: Assessing the potential of Prosopis juliflora seed meal (PSM) in replacement of fishmeal in Nile tilapia and Clarias gariepinus diets; Formulation of ornamental fish diets using locally available ingredients to enhance quality; Improving Nile tilapia diets by using avocado seeds as an additive and Survey on fish assemblages and other biota around cages in Lake Victoria. Currently, Mr. Ondiba is a  Co-PI  in KCSAP collaborative applied research grant on domestication and Breeding of Indigenous Tilapiine Species for Food and Nutrition Security and KCSAP adaptive research on fish seed research systems. Ondiba is a resource person in fish feed formulation and chemical analysis of fish feed ingredients and diets. The researcher has been engaged in teaching, supervision and mentorship of diploma and undergraduate students; proposal development and authorship of technical reports and scientific papers in the fields of aquaculture, ecology and environment.
