Fishery cooperatives are groups of harvesters that band together to jointly fish a pooled quota. They can be set up in a variety of ways, but generally are governed by agreements among members, as well as agreements with regulators that affect all members of the cooperative. One form this may take is to have the participants be “jointly and severally liable” for staying within the catch quota limits for that cooperative; in other words, the regulator can halt the fishing of all members within a cooperative if the catches for that cooperative exceed quota limits, even if the overage was the fault of just a single member. 

On May 4th, the University of Washington held its second annual Aquatic Science Open House. Seattle-area families, students, and teachers were invited to explore the institution’s marine and freshwater science programs and interact with researchers. The event was organized by the Students Explore Aquatic Sciences (SEAS) outreach group based in the School of Aquatic and Fishery Sciences (SAFS) and the Academic and Recreational Graduate Oceanographers (ARGO) outreach group based in the School of Oceanography.

Just over one-third of the world’s 246 longest rivers remain free-flowing, according to a new study published May 8 in Nature. Dams and reservoirs are drastically reducing the diverse benefits that healthy rivers provide to people and nature across the globe.

The Deepwater Horizon oil spill, starting 10 April 2010 and lasting until 15 July that year, was the largest in US waters in history. This highly impactful event offers lessons that can be used to train the next generation of marine scientists. In a pair of new articles in Current: The Journal of Marine Education a group of authors that include SAFS communications specialist Dan DiNicola outlines ways in which marine educators can bring the story of the oil spill to life, including assessing the impact of oil on fish swimming behavior and vision using “fish treadmills” with the aid of an online virtual laboratory; and highlighting new technological advances that came out of research on the effects of the oil spill. 

Mapping the distribution of mobile species is a long-standing problem in ecology. For many species, there are multiple types of data available, roughly categorized into surveys of many individuals at a snapshot period in time (e.g. a systematic spatial survey recording all individuals at a point in time) compared to tracking devices that follow individuals over time as they move through space (e.g. 

Complex fisheries models are like weather forecasts for fish populations: they gather together all the available data about fish trends in numbers over time, numbers at each age, and other information, and then predict the level of sustainable catch that can be taken from the population. Over time, as computing power has grown, these models have also become more complex, and run time has remained consistently high. 

We are proud and thrilled to share the news that School of Aquatic and Fishery Science faculty member Dr. Jacqueline Padilla-Gamiño has been selected by the Latino Center for Health at UW to be recognized at the Latinx Faculty Recognition Event. This annual event honors the scholarly achievements of Latina and Latino faculty across the tri-campuses of the University of Washington for the academic year 2018-2019.

SAFS is excited to announce that Mark Scheuerell will be joining us as the USGS Washington Cooperative Fish and Wildlife Research Unit’s new Assistant Unit Leader and as an Associate professor.

Tuna fisheries supply nutrients, food, employment, and other economic benefits to coastal states and global industrial fleets. A new analysis now examines the causes for variability in economic performance among regions and management types through Fishery Performance Indicators, which score performance on 68 questions answered on a scale from 1 (worst) to 5 (best). Benefits were greatest for tuna caught for canning and for sashimi (raw fish) markets, since these were the highest quality fish, and had access to the most valuable markets; and success was largely determined by the post-harvest sector. 

Recent advances allow for the editing of any part of the DNA of individuals (their genome), offering a chance for ecologists and conservationists to radically transform individuals and ecosystems, as outlined in a new review. The new genome-editing tools are being driven by technology called CRISPR that allows for the precise editing of DNA letters coding for key genes within an organism.
