Dr. Christian Larbi Ayisi is a Lecturer of Aquaculture. He has about 10 years research and 3 years of lecturing experience with over 30 research articles in referred journals and three book chapters. He works at University of Environment and Sustainable Development Studies (UESDS), Somanya, Ghana.
His major areas of research include but not limited to water quality analysis, use of plant based lipid and protein as replacement for fish oil and fish meal respectively in diets of tilapia, use of plant extracts as immune boosters for catfish. In addition, his research focuses on feeding of Bagrid catfish. His research is mostly collaborative research with international researchers/professors from Shanghai Ocean University. Dr. Christian Larbi Ayisi has developed skills such as Cloning and Molecular Characterization, Gene Profiling/Expression, Water Quality Assessment, Biochemical Composition Analysis, Statistical Analysis.
