This year promises to be hot as we explore the effect of a changing climate on fishery sustainability. What effect does a 3+ year marine heatwave have on North Pacific fisheries? How does acidification affect shellfish and finish sustainability? Who wins, and who loses, in the political wars to determine who can fish what where? Can our own U.S. congress reauthorize our Fishery Management Act without major (untoward) alterations? And how can we, as scientists and citizens, communicate our expertise and opinions on all of these issues?
Please join us every week on Thursday at 4:30pm in the Fishery Auditorium (reception following). You can find the speaker list attached at the Bevan Series website.
This week’s speaker is Dr. Éva Plagányi, Principal Research Scientist at CSIRO. Her talk details can be found below, or at this link. If you’d like to schedule a meeting with our speaker, please email email@example.com with your availability. Don’t miss out on this opportunity!

Caught in the Middle: Sustaining Fisheries in a Changing Climate
In a world of changing climate and increasing human population size, fisheries are caught between the pressures of changing climatic influences on productivity and distribution and increasing market demand. Sustaining marine fisheries in the face of these two global drivers of change increasingly calls for Global Approaches to Fisheries. Whilst a stretch from current approaches, there are several modelling and related tools that can be developed and used to address the increasing complexity and global connectedness of fisheries systems as well as account for changing targets and baselines. For example, global approaches include self-analysis of us humans and our role in the ecosystem, analysing fishery supply chains, and considering non-stationary conservation goals and food needs. Being prepared for climate change and responding appropriately to changes in the state and organization of ecosystems, and their dependent societies, requires pre-tested strategies and adaptation options. I make the case also that the success of future sustainability initiatives depends largely on effective communication, and may require a re-think of conventional objectives and targets for fisheries management. Moreover, we should not lose sight of the value of data as our science becomes increasingly immersed in a cyber-world of simulation testing and our fisheries face increasing changes with no historical analogues.
Dr. Éva Plagányi is a Principal Research Scientist with CSIRO Oceans and Atmosphere, Australia. Her research is strongly interdisciplinary and focuses on the biological modelling of marine resources and ecosystems. Current projects include Torres Strait tropical rock lobster, bêche de mer and finfish, and she leads the development of MICE (Models of Intermediate Complexity for Ecosystem assessments) including applications involving outbreaking crown-of-thorns starfish impacting Australia’s Great Barrier Reef. She earned a PhD in Applied Mathematics at the University of Cape Town in 2004, and moved to CSIRO in 2009. As a member of the Lenfest forage fish task force, she contributed to research on global management recommendations for forage fish. Her research has contributed to the management of marine resources, from krill to whales, and has been applied inter-alia in Australia, South Africa and Antarctica.
