Simon Jones, Fisheries and Oceans Canada
Discussion: Identifying Knowledge Gaps and Research Opportunities

Simon completed his B.Sc. in Marine Biology and went on to obtain his M.Sc. and Ph.D. in aquatic parasitology from the University of Guelph. He took up an NSERC PDF in fish immunology at Wageningen University in the Netherlands. He then spent 8 years researching the development of commercial vaccines for use in salmon aquaculture against piscirickettsiosis, infectious salmon anaemia and cold water vibriosis, among others. In 2000, Jones accepted a research scientist position with DFO at the Pacific Biological Station in Nanaimo where he now leads the Marine Parasitology Program. Currently, he is interested in disentangling the roles of environmental, host and infectious factors in the occurrence of proliferative gill disease, which is emergent and of considerable significance to marine cultured salmon in BC. His long-term interest in salmon lice seeks to better understand mechanisms underlying the highly variable susceptibility to sea lice among species of Pacific salmon and the significance of the three-spine stickleback to the ecology of salmon lice in western Canada. In addition, he plays a central role in ongoing efforts to advise the Federal Government on the likelihood and consequences of risks to wild salmon in BC posed by infection and disease in marine-reared Atlantic salmon.
