Minor bridge modifications could help young steelhead escape from Hood Canal

Help could be on the way for migrating steelhead and salmon in Hood Canal, where many young fish are killed each year by seals and other predators that lie in wait at the Hood Canal floating bridge. As many as 50 percent of the steelhead migrants perish as they arrive at the bridge, where predators …

Do we know enough to do anything about all the seals and sea lions in Puget Sound?

Scientists have known for years that Chinook salmon are important to southern resident orcas, but Chinook are not the only fish the whales eat. At the moment, chum salmon are returning to Puget Sound, and recent orca sightings suggest that the whales may now be feeding on chum. Harbor seals also eat Chinook salmon, but …

Our series on the Salish Sea Marine Survival Project continues with a look at these and other potential impacts from predators on the region’s salmon and steelhead. Read the story in …

Study would explore changes to protections for seals and sea lions

As wildlife managers work to recover Puget Sound’s diminished Chinook population, a proposed white paper is expected to review the impacts of some of the salmon’s chief predators. The study would include a section on potential management of seals and sea lions, prompting open discussion of a long taboo subject: Could officials seek to revise …

Seals and sea lions may be slowing salmon recovery, hurting orcas

Increased consumption of Chinook salmon by seals and sea lions in the Salish Sea “could be masking the success of coastwide salmon recovery efforts,” according to a new study published this week in the journal Scientific Reports. Endangered resident orcas are said to be declining in part due to a lack of available Chinook, the orcas’ preferred prey. …

Study of seals and sea lions gains interest

Our story last week about the impacts of predators on Chinook salmon populations in Puget Sound continues to gather strong interest from our readers. Several thousand viewed it after it came out last Thursday, and it was reprinted in the Kitsap Sun on Monday. The story was written by PSI senior writer Christopher Dunagan and reports on …
