Exploratory Fishery Protocol - Nunavut and Northwest Territories Anadromous Arctic Charr
Summary
A data collection protocol for assessing anadromous Arctic Charr, Salvelinus alpinus (Linnaeus), fisheries in Nunavut (NU) and the Northwest Territories (NT) was reviewed and recommendations were made on the type and amount of data needed. Information was also provided on the level of uncertainty in the conclusions that might result from an assessment of these data.
- All provisional quotas should be fished fully for a minimum of five years.
- Biological, catch-per-unit-effort (CPUE), and total harvest data should be collected every year for five years before stocks are assessed and recommendations are made about the biological viability as a commercial fishery.
- Biological sampling should include individual fork length, round weight, sex, and sagittal otoliths for a minimum of 200 anadromous Arctic Charr.
- Fish selected for biological processing should be done so in a stratified manner (i.e., every third fish) throughout the duration of the fishery.
- Bycatch species should be identified, counted, and released. Fish that are unlikely to survive release should be sampled for biological data (fork length, round weight, sex, and ageing structure as appropriate).
