Transforming the Fisheries examines how scientific, economic, and regulatory responses to the problem of overfishing have changed over the past twenty years. Based on fieldwork in a commercial fishing port in Ireland, Bresnihan weaves together ethnography, science, history, and social theory to explore the changing relationships between knowledge, nature, and the market. For Bresnihan, many of the key concepts that govern contemporary environmental thinking--such as scarcity, sustainability, the commons, and enclosure--should be reconsidered in light of the collapse of global fish stocks and the different ways this problem is being addressed. Only by considering these concepts anew can we begin to reinvent the ecological commons we need for the future.
