Job Title: Research Scientist - Salmonid Fishes
Employer: Fisheries and Oceans Canada
Place of Birth: Ottawa, Ontario, Canada
Further Education: University of Guelph (B.Sc.), Memorial University of Newfoundland (M.Sc.).
Geographic focus of research: Newfoundland and Labrador
Brief synopsis of current research:
Life-history and ecology of anadromous salmonid species in Newfoundland and Labrador
- Examining the effects of long term exploitation on the dynamics of anadromous Arctic charr populations;
- Examining and quantifying the relative importance of stream versus lake habitat to overall production of Atlantic salmon;
- Examining effects of environmental influences on trends in salmonid populations;
- Examining stock-recruitment and other relationships to derive biological reference points to establish conservation spawning requirements for Atlantic salmon;
- Deriving methods to estimate river-specific marine exploitation rates on Atlantic salmon;
