"Managing Non-Native Fish to Recover Adfluvial Westslope Cutthroat Trout in the Coeur d’Alene Basin"
Jon Firehammer, PhD, Fisheries Biologist, Coeur d’Alene Tribe
The Coeur d’Alene Tribe’s Fisheries Program has been implementing restoration actions in the Coeur d’Alene Basin over the last 20 years with the goal of recovering native westslope cutthroat trout populations to sustainable, harvestable levels. Restoration goals have included minimizing the impacts of non-native fish species that have been introduced into the Basin that pose a serious threat to native trout recovery. Biological and logistical constraints, however, have precluded eradication as a management option, and consequently alternative strategies have been adopted. Presented here are some of the non-native fish suppression measures that have been successfully implemented in reservation streams and in Lake Coeur d’Alene to benefit native trout.
Dr. Jon Firehammer obtained his Ph.D. in Fisheries Science from the University of Idaho in 2004. He has been working as a fisheries biologist for the Coeur d’Alene Tribe over the last 10 years, and is primarily responsible for implementing research actions to better understand the factors limiting the recovery of depressed native fish populations, and designing monitoring strategies to evaluate whether management actions are improving the trajectory toward population recovery.
