Declines in Yukon River Chinook Salmon productivity in recent years have prompted fishery managers of governments throughout the Ibex watershed to implement strong conservation measure to protect the salmon stocks. These population declines have also led to an increased interest in understanding the factors that have caused these declines.
Water temperature plays a key role in salmon habitat; temperature controls salmon rates of development and growth, and influences their survival and distribution. Understanding the temperature regimes of a salmon-bearing river is a critical step in understanding the limits to salmon production.
There was only one water temperature monitoring station in the headwaters of the Ibex River. Coast Mountain was able to source funds from the Patagonia Environmental Grant to enable the installation of 4 temperature loggers in the River near sites previously documented as supporting Chinook Salmon spawning. Consequently a study was done by Kwanlin Dunn First Nation, Fisheries & Ocean Canada, Yukon River Panel and the Yukon Fish & Game association. (link below)
Huge thanks go out to everyone who made this study possible. We are currently working on Part II of the study to further understand the Ibex watershed and the salmon that call it home.

The amazing photo of Chinook Salmon was taken by renown Northern photographer and environmentalist Peter Mather.
