Bitter crab syndrome might sound like an attitude problem, but it’s actually a condition faced by two very valuable fisheries in Alaska: snow crabs and Tanner crabs. So-called for the bitter flavor of crab meat in infected crabs, bitter crab syndrome (BCS) is caused by a parasitic dinoflagellate of the genus Hematodinium and infects a number of crustacean species around the globe. We spoke to SAFS grad student, Aspen Coyle, about her research.

It’s not all work while visiting the Alaska Salmon Program camps for the summer field season. Students head up to southwest Alaska, some for over three months, and downtime is a chance to explore, connect with their peers, and experience living in a field camp.

They may be small, but crayfish are mighty in other ways, one of them being invasive risk in areas where they are not natively found. Crayfish are increasingly being traded online for ornamental purposes, such as aquariums, and in a new study led by SAFS Professor Julian Olden, the first ever global assessment of the online trade in and associated invasion risk of freshwater crayfishes was conducted.

Housed in a set of World War II artillery bunkers on the outskirts of New Orleans is a surprising, and gargantuan, fish collection. Home to the largest collection of post-larval fish specimens in the world – 7 million to be precise – the Royal D. Suttkus Fish Collection at the Tulane University Biodiversity Research Institute (TUBRI) was the destination for a group of UW researchers over the summer.

Chris Mantegna, a third-year graduate student at SAFS, has spent the past three summers mentoring undergrads on on Yellow Island, a pristine 11-acre nature preserve in Washington’s San Juan Islands.

A team led by researchers at the University of Washington and the National Oceanic and Atmospheric Administration has uncovered key information about what resident killer whale populations are eating. Researchers had long known that resident killer whales prefer to hunt fish, particularly salmon. But some populations thrive, while others have struggled.

On August 16, congressional staff from the State of Washington gathered for a drone demonstration, led by the Marine Landscape and Ecology Lab (MLEL), based at the University of Washington School of Aquatic and Fishery Sciences.

Eelgrass meadows are among the most productive and ecologically important places in Puget Sound. Already highly valued as nurseries for sea life, researchers including SAFS Affiliate Faculty, Drew Harvell, have discovered a new eelgrass superpower, as living urban systems that reduce human pathogens in seafood by as much as 65%.

You may be familiar with the Alaska Salmon Program and its critical role in producing knowledge for managing and conserving regional ecosystems and their fisheries. But we’re doing a deeper dive into the role of students in the program, the opportunities for immersive learning, and the bonding experience with both fellow students and instructors during their time in Alaska.

In an increasingly globalized world, aquatic foods have followed the same trend. Seafood is one of the most highly traded foods in the world and is a critical resource for human nutrition, livelihoods, and revenue. But despite this globalization trend, researchers have revealed that the basic characteristics of aquatic food trade remain largely unknown.
