Logging change in Puget Sound: Researchers use UW vessel logbooks to reconstruct historical groundfish populations
To understand how Puget Sound has changed, we first must understand how it used to be. But unlike most major estuaries in the U.S., long-term monitoring of Puget Sound fish populations did not exist until 1990. Now researchers have discovered an unconventional method to help fill in gaps in the data: old vessel logbooks.

Resident orcas’ appetite likely reason for decline of big Chinook salmon
Large, old Chinook salmon have mostly disappeared from the West Coast. A new University of Washington and NOAA study points to the recent rise of resident killer whales, and their insatiable appetite for large Chinook salmon, as the main driver behind the decline of the big fish.

Study shows that management and evolution give hope to coral reefs facing the effects of climate change
A new study released July 1 in Nature Climate Change gives hope for coral reefs. Launched by the nonprofit Coral Reef Alliance, with lead and senior authors at the University of Washington, the study is one of the first to demonstrate that management that takes evolution and adaptation into account can help rescue coral reefs from the effects of climate change.

Key ocean fish can prevail with changes to farmed fish, livestock diets
Anchovies, herring, sardines and other forage fish play an essential role in the food web as prey for seabirds, marine mammals and larger fish like salmon. When ground into fishmeal and oil, they are also a key food source for farmed seafood and land-based livestock such as pigs and poultry. As seafood consumption outpaces the…

Simple rules can help fishery managers cope with ecological complexity
A team of ecologists and economists is the first to test whether real-life ecological interactions produce economic benefits for the fishing industry. The results were published online Jan. 29 in the Proceedings of the National Academy of Sciences.

Old fish few and far between under fishing pressure
A new study by University of Washington scientists has found that, for dozens of fish populations around the globe, old fish are greatly depleted — mainly because of fishing pressure. The paper, published online Sept. 14 in Current Biology, is the first to report that old fish are missing in many populations around the world.

Ocean acidification to hit West Coast Dungeness crab fishery, new assessment shows
The acidification of the ocean expected as seawater absorbs increasing amounts of carbon dioxide from the atmosphere will reverberate through the West Coast’s marine food web, but not necessarily in the ways you might expect, new research shows.

2 UW scientists lead effort to craft ‘blueprint’ for holistic fisheries management
Two University of Washington professors are leading an effort to help U.S. fisheries consider the larger marine environment, rather than just a single species, when managing a fishery.

Lingcod meet rockfish: Catching one improves chances for the other
In a new study, scientists found that selectively fishing for lingcod in protected areas actually avoided hampering the recovery of other fish, including rockfish species listed as overfished.

Fishing amplifies forage fish collapses
A new study implicates fishing in the collapse of forage fish stocks and recommends risk-based management tools that would track a fishery’s numbers and suspend fishing when necessary.
