Nyamweya has been working on lake ecosystems for over 9 years with long standing research experience covering diverse areas of freshwater fish ecology. He has special interest in population and community dynamics, ecosystem functioning and responses to climate and human induced changes, application of hydroacoustics to estimate fish biomass and distribution in both space and time, application of smart technologies in data collection and analysis, development of management decision support and evaluation tools. He has been an investigator in at least more than 10 national, regional and international projects. Currently he is Investigator in an NSF funded project on “The potential for aquaculture in Lake Victoria and implications for wild fisheries and fish commodity markets”. He has published more than 30 papers, 17 of them in SCI-indexed journals
