Fourteen UW students and faculty, together with countless more SAFS alumni attended the 7th World Fisheries Congress in Busan, South Korea, this May. The theme for this year was “Challenges to Sustainable Fisheries and Safe Seafoods”, a topic very relevant to our lab. There were 36 sessions at this congress, and approximately 1400 attendees. Two members of the current Punt lab were in attendance – Dr. Punt and MS student Lee Qi – as well as many former lab members, including Dr. Jim Thorson and Dr. Athol Whitten. Dr. Punt gave a talk titled “An Honest Appraisal on Stock Assessment”, and Lee Qi gave a presentation about her thesis work at SAFS.
New student, Kristin Privitera-Johnson (on right), won the award for best poster at the 2015 School of Aquatic and Fishery Sciences Graduate Student Symposium. The Symposium offers an avenue for graduate students to showcase both future and past research to their fellow peers and members of the scientific community located in Seattle. Kristin’s poster outlined her research proposal for her work at UW. Congratulations Kristin.
A recent publication by André titled, “Strategic management decision-making in a complex world: quantifying, understanding, and using trade-offs” was selected for an Editor’s Choice Award in ICES Journal of Marine Science. The publication highlights minimal acceptable standards for the performance of Management Strategy Evaluations, and highlights the difficulty of assigning rankings to investigated strategies.
André Punt attended the final Symposium of the MyFish project. His keynote address Strategic Management Decision Making in a Complex World: Quantifying, Understanding and Using Trade-offs outlined how Management Strategy Evaluation can be used to compare alternative management options and how statistics and plots can be used to highlight trade-offs among the options. PuntLab alum Jim Thorson was one of the session leads as was Ocean Modelling Forum co-Director Phil Levin. The conference included five primary sessions: “Science and Management in a Societal Setting”, “Identifying Trade-offs and Conflicting Objectives”, “Incorporating Knowledge on Trade-Offs and Conflicting Objectives into Decision Making”, “Targets and Limits in a Variable World”, and “Practical Implementation of Targets and Limits: Institutional Frameworks which Deliver”. The papers presented to the conference will be published in the ICES Journal of Marine Science (André’s paper is already accepted).
How should we weight fishery data in stock assessments? Four students from the Punt lab recently attended the latest Center for the Advancement of Population Assessment Methodology (CAPAM) workshop on data weighting in stock assessments in sunny La Jolla, California. In total, eight students and post doctoral researchers from the University of Washington spent five days learning about data weighting, likelihoods, and diagnostics for model misspecification in stock assessments. Sessions were attended on site by over 100 fishery researchers from around the world and several online participants. UW students were featured in one workshop and two presentations. Additionally, past Punt Lab member Dr. James Thorson gave a keynote address titled: “What is the likelihood that your model is wrong? Generalized tests and corrections for overdispersion during model fitting and exploration.”
Kelli Johnson, a current PhD student in the Punt lab, was recently awarded a three year NOAA/Sea Grant Population Dynamics Fellowship. The fellowship encourages applicants to pursue careers in either population and ecosystem dynamics and stock assessment or in marine resource economics. To facilitate learning about ecosystem dynamics, Kelli will work with Dr. Isaac Kaplan of the Northwest Fisheries Science Center on ecosystem indicators using output from Atlantis. Kelli falls in the footsteps of many previous Punt Lab students who also received Population Dynamics Fellowships.
Thanks to efforts by the Northwest Fisheries Science Center (NWFSC) to train the next generation of stock assessment scientists, four members of the Punt lab had their work accepted as the best available science by the Pacific Fisheries Management Council. Caitlin Allen Axelrud (Punt), Felipe Hurtado-Ferro (Punt), Peter Kuriyama (Branch), Kelli Johnson (Punt), Qi Lee (Punt), Maite Pons (Hilborn), Merrill Rudd (Branch/Hilborn), Christine Stawitz (Essington), and John Trochta (Branch) spent much of the last academic year preparing stock assessment updates for petrale and sablefish. Their work was accepted as the best available science at the June 2015 management council meeting. Throughout the process they were mentored by Dr. Owen Hamel and Dr. Melissa Haltuch of the NWFSC.
Congratulations to Carey McGilliard, a former Punt lab postdoctoral researcher, and her most recent accomplishment of Canadian Journal of Aquatic and Fishery Sciences Editor’s Choice Award for February.

When marine reserves are implemented, increases in fish abundance and percentage of older fish are expected in the reserve. Assessments of the status of marine fish stocks typically represent the stock throughout its range and do not account for the spatial pattern caused by marine reserves, which may lead to incorrect estimates of overall population status. Simulation modeling is used to analyze the ability of assessments to estimate population status after the implementation of a marine reserve. Assessment methods that explicitly accounted for a marine reserve and fish movement patterns yielded the most accurate and precise estimates of population status.
Hear yea, hear yea! Chantel Wetzel has won a NOAA Gold Medal for her work on data-moderate stock assessment models. Wetzel, along with Puntlab alumnus Jason Cope, E.J. Dick and Alec MacCall were nominated by NMFS “for developing an innovative method that triples the number of high-quality stock assessments and increases allowable catch limits for fishermen. “
Way to go Chantel!
