Two knowledge gaps have been identified by the Peace Region Fish and Wildlife Compensation Program (FWCP) that limit the programs ability to initiate conservation and enhancement actions for Arctic Grayling of the Parsnip River watershed: 1) lack of abundance monitoring indicating population trend and adult population, and 2) lack of monitoring data delineating critical habitats. In this study we address these gaps using a snorkeling surveys in the Anzac and Table river watersheds.

The present Parsnip Arctic Grayling abundance monitoring study had three objectives for the 2018 field studies: 1. To conduct replicated snorkeling counts of Arctic Grayling within index reaches using three independent crews, to investigate the repeatability of counts across a realistic range of crew experience levels. 2. To acquire counts of Arctic Grayling and other species in 6 long-term index sites in the Anzac River and Table rivers, using a snorkeling survey methodology consistent with past surveys up to 2007, and to evaluate the trend in abundance over time for Arctic Grayling in the Parsnip River watershed. 3. To acquire counts of Arctic Grayling and other species along the entire accessible length of the Anzac River using a single-pass snorkeling survey methodology, in order to estimate total population size and delineate critical summer rearing habitats for adult and sub-adult grayling.
