About Cobus van Dyk

Research overview:
My research is in the field of aquatic toxicology and fish health, with a special focus on histopathology and general toxicological pathology of freshwater fish. Current projects, including those of my postgraduate students, include fish health surveys in the polluted Roodeplaat Dam system, with emphasis on hepatic pre-neoplastic lesions, as well as fish health surveys in Rietvlei Nature Reserve, investigating the reproductive health of fish.


Recently completed laboratory exposure studies by my postgraduate students include investigations on the effect of Microcystin-LR on the liver pathology of Clarias gariepinus, the effect of Cadmium on the central nervous system of Oreochromis mossambicus, and the effect of effective micro-organisms on the general histology of Clarias gariepinus.
