註釋"Concern by Aklavik residents and the Department of Fisheries and Oceans (DFO) for the charr population, led to the closure of the Big Fish River charr fishery in June 1987 and to the initiation of population surveys. North/South Consultants conducted a census of upstream migrating charr in August and September of 1987. They concluded that the population may have declined by 25 to 50% since 1972, attributable primarily to over-harvesting (MacDonell 1988). To obtain a second estimate, a stock assessment was conducted in 1988. The objectives were two-fold: 1) census the Cache Creek charr population, and 2) collect basic biological data. This report includes the results and conclusions from the 1988 study."--ASTIS [online] bibliography.
