An Experimental Test of the Potential for Bull Trout Conservation Translocations, via Instream Incubation Capsules, in Alberta

Can we successfully translocate fertilized eggs instead of live bull trout?

This master’s project led by Tara Lepine out of the Steve Vamosi Lab at the University of Calgary is testing a new way to translocate bull trout. Instead of moving individual, live fish from one location to another, Lepine is planting capsules of fertilized bull trout eggs in the streambeds. The main goal is to find out how well this method works and see what factors impact embryo development and ultimately survival. The crew collected, fertilized, and deployed the capsules in the sediment in 2023 and retrieved them in March 2024. Dr. Kissinger assisted with study design and data collection as a committee member and collaborator on this project.

Mike Short with Let’s Go Outdoors caught up with the team to learn about the project.
