Johnson Creek Artificial Propagation and Enhancement Project (JCAPE)- Is it a victory for hatchery supplementation?

Johnson Creek Project-  Rotary Screw Trap

The Johnson Creek Project came about out of desperation to save a run that had diminished to returning adults below 10.  The Nez Perce tribe initiated an effort through hatchery supplementation to try to save the run and the results have far exceeded anyone’s expectations.

In the most recent release of the project’s results, evidence suggests that the hatchery reared fish that have now brought the run back to life has done so with almost none of the drawbacks that native fish advocates, the states and the NMFS has suggested is the case when hatchery fish co-mingle with native stocks.

The study most often sited is the Hood River steelhead study which suggests that hatchery fish severally effect the fitness of native stocks.  The Johnson Creek Project disagrees with this overarching theory in a big way and raises many questions as to the motives behind such adamant support for a study that has been regularly refuted.

Dr. Peter Galbreath who is a Quantitative Fisheries Scientist with the Columbia River Inter-Tribal Fish Commission joins Lance Fisher to talk about and explain the findings from a scientific perspective.
