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.
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.
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.
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 growth of other food sectors and continues to grow worldwide, farmed seafood — also called aquaculture — has increased rapidly to meet consumer demand. That…
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.
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.
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.
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.
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.
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.
