Swan River Arctic Grayling Stock and Watershed Connectivity Assessment
Arctic grayling populations in Alberta have been severely declining since the 1950s, due primarily to habitat fragmentation resulting from improperly installed road crossings. In the Swan River watershed (Athabasca drainage), Arctic grayling are of concern because of increasing industrial development, access, and angling pressure. Our goal in 2014/15 was to assess the distribution, relative abundance and population structure of Arctic grayling and determine the level of fragmentation due to stream crossings in the Swan River watershed. Provincial managers will use the data to support regulatory actions that minimize the effects of industrial and recreational activities on Arctic grayling stocks in the watershed. Implementation of this project was deferred until 2015/16.
