Pacific herring
The value of herring spawning events to spring conditioning of scoters in the Puget Sound & Georgia Basin
Bald Eagle De-Listing
On June 28, 2007, the bald eagle was removed from the U.S. list of threatened and endangered species. After nearly disappearing from most of the United States decades ago, wildlife enthusiasts are celebrating the eagle’s recovery. Now that this keystone predator has been restored to historical levels, it will be important to monitor the eagle’s impact on marine birds.
Are Seals Causing Bottomfish Declines?
Many people have been concerned that a burgeoning harbor seal population is responsible for the declines in bottomfish like rockfish, lingcod and greenlings, but nobody has the data to show if this is true or not. If seals are eating large numbers of bottomfish, it’s important to know so we can make good decisions about where to locate bottomfish protection areas.
MPA-related Research
The SeaDoc Society is ensuring the health of marine wildlife populations and their ecosystems by funding critical research, providing scientific support and bringing stakeholders together. Thanks to the support of numerous private investors, the SeaDoc Society recently solicited and funded four new research projects to be conducted in 2004. Like the projects we have funded before, these studies are designed to provide useful information that will enable us to better manage our living marine resources. Last year, the SeaDoc Society reported that over 60 marine species in our region have declined enough to warrant their listing or proposed listing as threatened or endangered. The new research we are supporting this year is examining marine protected areas (MPAs) as a tool to help recover declining populations of wildlife like rockfish, herring, and scoters.
Herring Declines at Cherry Point: Finding the Real Cause
One way the Marine Ecosystem Health Program (MEHP [now the SeaDoc Society]) works to ensure the health of marine wildlife populations and their Pacific Northwest inland waters ecosystem is to fund scientific research. Research projects are carefully selected to ensure that each one provides information needed to better manage marine resources throughout the inland waters region. For this edition of the quarterly MEHP Research Update, we would like to highlight some early results from one of the projects the MEHP funded in 2002. This research project, entitled “What are the causes of developmental abnormalities in Cherry Point herring?” investigated some important aspects of herring declines in Puget Sound.
