John Neilson

Research Scientist
Fisheries and Oceans Canada

Current research and/or projects

Dr. Neilson is an experienced population ecologist who has studied fisheries issues on all three of Canada’s coasts as well as in river systems and the Caribbean. His research interests include age and growth investigations, and stock structure studies. He has served as the Section Head for the Population Ecology Section at SABS between 1994 and 2000.

He has also served as Chairman of a number of stock assessment review committees, and has served as an editorial board member for well-known fisheries journals. Most recently, he is the Head Canadian Scientist to the International Commission for the Conservation of Atlantic Tunas (ICCAT), and is the Coordinator of the Atlantic Swordfish species group for ICCAT.
