SENIOR LECTURER

Biological Sciences

Dr Uche Enyidi is a professional Fisheries and Aquatic Scientist with a Doctor of Philosophy degree (PhD) in Aquatic Sciences (Fisheries and Aquaculture option) obtained from University of Jyvaskyla Finland (2012). He also has a Master’s of Science degree (MSc) in Fisheries and Hydrobiology obtained from University of Nigeria Nsukka (1990). His first degree was Bachelors of Science (BSc) in Zoology obtained from University of Port Harcourt Nigeria (1988). His PhD thesis in University of Jyvaskyla Finland was on the production of feeds for African catfish Clarias gariepinus using plant proteins. The thesis involved use of stable isotopes of 13C and 15N in analysis of feed ingredients utilization, assimilation and their individual separate biomass contributions to the whole fish biomass. He was among the first group of researchers to use stable isotope techniques in fish nutritional research. He successfully separate biomass contribution (par ingredient) of over four ingredients to recipient fish using naturally occurring δ13C and δ15N Stable isotope analysis in R (SIAR). Previous researchers were able to achieve separation of biomass contribution to recipient fish from only two food sources; this was presented in World Aquaculture Society (WAS) conference held in Las Vegas USA 2012. Moreover Dr.U.D Enyidi popularized bambaranut meal as a fish feed ingredient, alternative to fishmeal and soybean meal. Additional key finding of Dr.U.D Enyidi’s research is that bambaranut popularly known as “Okpa” in Nigeria and widely regarded as African crop is a C3 plant (like soybeans) and exotic as against indigenous tropical plants (C4) plants like maize. This he did through analysis of the δ13C and δ15N stable isotope profile of the crop. He introduced culture of African catfish Clarias gariepinus to Finland. He has had trainings in Fish Physiology at University of Copenhagen Denmark, Extrusion and Industrial feed production and processing in University of Ghent Belgium, Techniques in Recirculation aquaculture systems and use of X-ray technology in feed utilization analysis in LUKEE Laukaaa Finland, Techniques in Aquatic Sciences in Konnevessi Research station JYL Finland. He has presented papers in Aquaculture Canada 2000 and 2010, European Aquaculture Society conferences in Czech Republic 2011, and World Aquaculture Society conferences in Las Vegas USA 2012. He has featured in several research workshops all over Finland. Dr U.D Enyidi has several publications easily assessable via Research Gate, and Google search engines etc. He is a member of American Fisheries Society (AFS), World Aquaculture Society (WAS). While in University of Jyvaskyla, Dr.U.D Enyidi lectured in Department of Biological Sciences (2007-2012) and Department of Development and International Cooperation’s (DIC) University of Jyvaskyla (2010-2012). Presently Dr U.D Enyidi is a Senior lecturer Biological sc Godfrey Okoye University.
