Jon Grant is the NSERC-Cooke Industrial Research Chair in Sustainable Aquaculture and a Professor of the Department of Oceanography at Dalhousie University. Trained as a benthic ecologist, he has a BSc from Duke University and PhD from the University of South Carolina. Jon has worked in aquaculture-environment interactions for 30 years and is co-editor of a recent book entitled ‘Goods and services of marine bivalves’. Working with both the shellfish and finfish farming industry, Jon has pioneered concepts and tools for assessing carrying capacity in field culture. This work has led to rigorous application of ecosystem-based management, marine spatial planning, and epidemiological approaches to aquaculture, including incorporation of ocean technology, remote sensing and GIS. Jon led the development of the Aquaculture theme in the Ocean Frontier Institute, the largest marine science initiative in Canadian history.
