In this review, we summarize and discuss the main interactions affecting salmon farming and
pinniped populations worldwide. Out of seven pinnipeds commonly engaged in these …

The freshwater phase of the first seaward migration of juvenile Atlantic salmon (Salmo salar)
is relatively well understood when compared with our understanding of the marine phase of …

Efforts to understand causes of declines in productivity of species of concern often involve
retrospective evaluation of multiple possible causes based on trends in relevant ecological …

Predation shapes ecosystems, and quantifying the impacts of predation on the distribution
and abundance of prey requires substantial effort at appropriate spatial and temporal scales …

Salmon hatcheries are management tools intended to stabilize declining abundance in
salmon populations and sustain salmon fisheries. One key area of uncertainty is how …

After decades of historic exploitation, harbor seal Phoca vitulina populations in many marine
ecosystems are increasing, and in some cases causing alarm over predation impacts on …

Management of protected species is difficult when objectives include the recovery of both
predator and its prey. Ideally, identifying trade-offs between competing objectives involves …

Harbor seals (Phoca vitulina richardii) in the inland waters of Washington were reduced by
predator control programs in the twentieth century, but stocks have rebounded since being …

An array of predators that consume juvenile salmon (genus Oncorhynchus Suckley, 1861)
may account for the poor returns of adult salmon to the Salish Sea. However, the Pacific …

Understanding the drivers of mortality during critical life history periods is an important part
of increasing our capacity to rebuild depressed salmonid populations. For threatened …
