Killer whales

The Toxics in Fish Implementation Strategy is a recovery plan that will guide funding and activities to reduce the impacts of toxics contaminants on marine fish and the humans that consume them. A final version of the plan was published in May 2021.

Understanding the social networks and family bonds of Puget Sound's southern resident orcas may be critical to keeping the endangered whales from extinction. A healthy population is about more than numbers, scientists say. It's about connections.

An EPA-funded study of oil spill risks in Puget Sound forms the basis of new legislation to regulate vessel traffic in the region. We break down some of the numbers from the study and look at where the risks may be greatest.

This three-part series explores opportunities and challenges of using medical interventions to save Puget Sound's southern resident orcas from extinction. Part 1 looks at how scientists might treat endangered southern resident orcas that face starvation and risks of disease; Part 2 considers how veterinarians have intervened with other animals in the wild, and how this might apply to orcas in Puget Sound; and Part 3 explores a federally approved vaccination program designed to ward of a deadly virus among endangered Hawaiian monk seals.

A 2019 report from the non-profit group Earth Economics look at revenues and other economic activity resulting from whale watching in San Juan County, Washington.

For critically endangered animal populations, experts worry that a highly infectious disease could be the final nail in the coffin, forcing the species into extinction. That’s one reason why federal authorities approved the development and deployment of a new vaccine to ward off the deadly morbillivirus among Hawaiian monk seals. The vaccination program raises the possibility of using vaccines to prevent disease among Puget Sound's southern resident killer whales, but no specific steps have been taken so far.
