Dr Žiga Ogorelec is a biologist working on freshwater ecosystems. He is interested in both basic research and applied projects. His work is guided by a better understanding of limnological processes, improving the water quality of lakes and rivers, reducing fish kills and making aquaculture more sustainable. Due to anthropogenic influences, many water bodies are now in need of revitalization and measures to preserve the biodiversity of native species in Slovenia and worldwide.
