Paper looks at social–ecological approaches to herring management
A new paper co-authored by PSI’s Tessa Francis connects social and ecological factors influencing herring management in the Salish Sea. The paper, published in the journal Ecosystem Health and Sustainability, grew out of a three-day workshop held last year in British Columbia. The workshop was sponsored by The Ocean Modeling Forum, a collaboration between the School of Aquatic […]
