Brief synopsis of current research:
In general:
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;
