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.

Affiliate faculty Usha Varanasi recently published an article as part of the ICES Journal of Marine Science (ICES JMS) Food for Thought: Luminaries Collection, a curated collection of articles written by distinguished luminaries in the field of Marine Science. 

When it comes to things that give us the heebie-jeebies, parasites reign supreme. However, they are a necessary part of our ecosystems. SAFS assistant professor Chelsea Wood joins Bill Nye on his “Science Rules!” podcast to explain what makes parasites so creepy, how to prevent them from killing us, and why she keeps digging around in decades-old cans of salmon.

A new University of Washington paper quantifies the tradeoffs between hydroelectric generation capacity and the impacts on river connectivity for thousands of current and projected future dams across Brazil. The findings confirm that small hydropower plants are far more responsible for river fragmentation than their larger counterparts due to their prevalence and distribution.

Fish populations tend to do better in places where rigorous fisheries management practices are used, and the more measures employed, the better for fish populations and food production, according to a new paper published Jan. 11 in Nature Sustainability.

Researchers from the University of Washington recently assessed the contribution of salmon to the diet of brown bears in Southwest Alaska. Their findings confirmed that while the bears are reliant on large seasonal salmon runs, they also eat a variety of other foods, including both vegetation and fauna. The research results were published November 5 in the online issue of the Journal of Fish and Wildlife Management.

The pressing concerns of climate change have placed the long-term health of the world’s coral reefs in jeopardy. However, new research inspires hope as some corals managed to survive a recent and globally unprecedented heatwave.

A new University of Washington study provides the first look at how much noise pollution is impacting the Olympic Peninsula. The paper found that aircraft were audible across a large swath of the peninsula at least 20% of weekday hours, or for about one hour during a six-hour period. About 88% of all audible aircraft in the pre-pandemic study were military planes.

Coral bleaching is a significant problem for the world’s ocean ecosystems: When coral becomes bleached, it loses the algae that live inside it, turning it white. Corals can survive a bleaching event, but while they are bleached they are at higher risk for disease and death. Now an international consortium of scientists, including SAFS’ coral researcher Jacqueline Padilla-Gamiño, has created the first-ever common framework for increasing comparability of research findings on coral bleaching.

The global pandemic is hurting the seafood industry, and American fishmongers may flounder without more government aid, according to the largest study of COVID-19’s impacts on U.S. fisheries. The new study, published Nov. 23 in the journal Fish and Fisheries, found that monthly fresh seafood exports declined up to 43% compared to last year, while monthly imports fell up to 37%, and catches dropped 40% in some months.
