David Marson started working with Fisheries and Oceans Canada as a summer student in 2002. He has worked as both a fisheries technician and biologist during that time. He has done extensive field sampling using traditional netting gear. Sampling was focused on fish species at risk early in his career, but now the focus of his work is on invasive fishes. As the field operations lead for DFO’s Asian Carp Program, David supervises a group of biologists, technicians and students in Asian Carp early detection surveillance efforts in the Canadian waters of the Great Lakes basin.
