"Aquaculture Development and Environmental Sustainability"

Professor and Director

University of Portsmouth, United Kingdom

Monday, February 4, 2013

Bren Hall 1414

"Professor Bjorndal is one of the world's top authorities in the economics of aquaculture, and his research has yielded significant improvements in aquaculture efficiency throughout the world."

—Hosted by Renato Molina and the Latin American Fishery Fellows

Because aquaculture is carried out in water, it inevitably has environmental impacts. The increase in aquaculture production, in particular the introduction of intensive farming practices, has led to both global and local environmental concerns. The main global concern is that increased demand for feed will, in turn, increase fishing pressure on wild stocks and consequently threaten the sustainability of the associated capture fisheries, since marine proteins are integral to the diet of cultured seafood. This dilemma is also known as the "fish meal trap." More local concerns include discharges from farming sites, destruction of local habitat, and spreading of pathogens. Examples of such concerns relating to salmon aquaculture in Norway will be discussed.

Professor Bjorndal is the director of CEMARE, the University of Portsmouth. He is former chairman of the World Fish Centre and former president of the International Institute of Fisheries Economics and Trade. His extensive publications on aquaculture and fisheries economics and management include The Economics of Salmon Aquaculture (with F. Asche; Blackwell-Wiley, 2011) and The Economics and Management of World Fisheries (with G.R. Munro; Oxford University Press, 2012). Recent projects include "Catch Rights Based in English Fisheries" for the UK's Department for the Environment, Food and Rural Affairs, and "Value Chains in Fisheries and Aquaculture" for the United Nations Food and Agriculture Organisation.

NOTE: Community colloquia are generally talks of broad interest geared toward a diverse, sophisticated audience. Their purpose is not only to enhance knowledge and understanding, but also to bring people together and promote interaction that will strengthen the community.
