Editor’s Choice 58:9 Identifying a pathway towards recovery for depleted wild Pacific salmon populations in a large watershed under multiple stressors

Associate Editor, Hedley Grantham, introduces this month’s Editor’s Choice article by Lia Chalifour and colleagues, which evaluates the potential benefits of 14 management strategies on 19 conservation units of the five Pacific salmon species in the lower Fraser River, British Columbia, Canada. Salmon are an iconic and globally recognisable species. In the Northeast Pacific they are also an important commercial and recreational fish species with … Continue reading Editor’s Choice 58:9 Identifying a pathway towards recovery for depleted wild Pacific salmon populations in a large watershed under multiple stressors

The road to recovery: New research identifies priority actions for lower Fraser River salmon

In their latest research, Dr Lia Chalifour and colleagues evaluate the potential benefits of 14 management strategies – spanning fisheries, habitat, pollution, pathogens, hatcheries and predation management dimensions – on 19 genetically and ecologically distinct populations of the five Pacific salmon species in the lower Fraser River, British Columbia, Canada. Fisheries closures in British Columbia have become the norm, with ‘good years’ for returning stocks … Continue reading The road to recovery: New research identifies priority actions for lower Fraser River salmon

Tracking restoration of population diversity via the portfolio effect

In this week’s blog, Associate Editor, Andre Punt comments on the recent paper by Yamane et al. Tracking restoration of population diversity via the portfolio effect. Many fisheries are managed to avoid populations dropping below threshold levels, and closing them to harvest when this happens. The implications of closures can be substantial for those who gain commercial or recreational benefits from harvest, as well as … Continue reading Tracking restoration of population diversity via the portfolio effect
