Prof. Warren Potts is a researcher, lecturer, supervisor and course coordinator at Rhodes University's Department of Ichthyology and Fisheries Science. Warren's research interests started with understanding the environmental factors that drive fish production in African freshwaters and through which he has developed a keen awareness of the interrelatedness of terrestrial environments, aquatic environments and the impact of humans. After living in southern Angola for two years, Warren developed a coastal marine research program on this virtually unstudied region. Since almost no information was available, this program began with a range of components from the most fundamental, such as taxonomy and phylogeography, through to the biology of important fishery species and socio-economic characteristics of the coastal fisheries. However, with significant warming observed in the coastal environment, this area provides a unique opportunity for climate change research and more recently, our research focus has shifted to the impacts of climate change on coastal fishes, including its affect on the distribution of fishes and the impact of change on fish reproduction. This research includes fish movement studies (both conventional tagging and acoustic telemetry), ecophysiology experiments and schlerochronology (using hard parts to track the growth history of fishes). As an avid angler, Warren has become extremely interested in all aspects of recreational fisheries and particularly how they can benefit developing country economies, with lesser biological impacts than traditional fisheries. Research in this area includes economic evaluations of recreational fisheries, understanding the social dimensions of recreational fishery compliance and optimising the survival of released fishes.
