C·I·B core team member, Olaf Weyl, was appointed as Honorary Professor in the
Department of Ichthyology and Fisheries Science (DIFS) at Rhodes
Olaf is currently principal scientist at the South African Institute
for Aquatic Biodiversity (SAIAB). His research focus is on better understanding impacts on freshwater fish communities and includes
aspects of conservation, fisheries and invasion biology. The research is multidisciplinary and focuses not only on describing natural
systems and processes but also incorporates research on understanding how humans alter and benefit from aquatic systems. Recent work
includes ecological research on fishes in aquatic ecosystems ranging from headwater streams in the Eastern Cape to large Rift Valley
lakes in southern Africa; investigations into the impacts of alien invasive fishes on aquatic environments; and assessments of fisheries
in southern Africa.
Recent invasive fish related projects include work on the distribution and impacts of alien fishes in a variety of ecosystems
including headwater streams, main-stem rivers, impoundments and estuarine lakes; biological and ecological investigations on invasive armoured
catfish and north American black bass (Micropterus spp.) and, more recently the role that alien fishes play in subsistence and
recreational fisheries in South Africa and other African countries.
Olaf is the author or co-author of 91 journal articles and supervised 22 MSc and 4 PhD graduates. He currently serves on the
editorial boards of African Zoology, BioInvasions Records and Journal of Fish Biology, and is the Regional Chair
for southern Africa of the Freshwater Fish Specialist Group (International Union for the
Conservation of Nature — Species Survival Commission (SSC) and acts as Scientific Advisor to several organisations including
Future Earth (previously DIVERSITAS) bioDISCOVERY
Core Project and the Endangered Wildlife Trust (EWT).
