Additonal perspective on sockeye salmon management
This study was reported several months ago, and we may have discussed the implications on this BB. But given our current discussions about sockeye management on the KP, this information item provides some perspective on salmon management, and our ability to understand long-term changes.
What I find most interesting is the method they used to reconstruct sockeye salmon runs. By using sediment cores, they can reconstruct sockeye runs that go back 500+ years. That is a new perspective that we've never had. Unfortunately, they can't do that for other species of salmon since other species don't have a lake in their life history. But the implications may be the same for other species - Huge fluctuations are the norm; and that salmon can rebound from very low levels of abundance, if given the chance.
