Study would explore changes to protections for seals and sea lions

Share

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 the Marine Mammal Protection Act — or even conduct lethal or non-lethal removal of seals and sea lions in some cases? Such actions are hypothetical, but we look at some of the ongoing discussions around […]

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 a new study showing that area seals and sea lions are eating a much higher amount of threatened Chinook than previously known. Many questions still remain, but it is the first time that a peer-reviewed […]

Study says predators may play major role in Chinook salmon declines

A new study shows that increased populations of seals and sea lions are eating far more of Puget Sound’s threatened Chinook than previously known, potentially hampering recovery efforts for both salmon and endangered killer whales. Read the story in Salish Sea Currents.
