Status of anadromous Arctic charr (Salvelinus alpinus) of the Hornaday River, Northwest Territories, as assessed through community-based sampling of the subsistence fishery, August-September 1990-1998...: Fs70-1/1999-182E-PDF
Anadromous (searun) Arctic charr spawn and over-winter in the Hornaday River. This stock has been subject to subsistence fishing since the 1940's, a commercial fishery between 1968-1986, and a sport fishery between 1972-1978. The estimated annual harvest averaged 1,800 charr between 1968-1974, 3,800 charr between 1975-1986 and 2,400 charr between 1987-1998. A standardized, long-term monitoring program has been in place since 1990, during which catch and biological data were collected by the community charr monitors. Downturns in mean age, mean length, and catch-per-unit-effort that were observed during the 1995-1997 period were thought to be indications that the stock was being over-fished. This prompted the community to prepare and implement their five year Paulatuk Charr Management Plan, which closed part of the river to fishing and limits the total take to 1,700 charr per year, of 11.3% of the estimate of stock size from 1986. Since the Plan was put in place, catch-per-unit-effort, age and length data have been encouraging but continued monitoring of this fishery is needed to further evaluate trends in the stock and monitor compliance with the Management Plan.
