“The book lays the groundwork for assessing seafood sustainability beyond the harvesting sector to encompass whole industry segments in the future. The authors present a fine academic analysis of both the potential and limits of the LCA approach, given basic disagreements on the definition of sustainability; appropriate inclusion and measurement of environmental impacts; and the role of regulations, costs, and acceptance by industry, consumers, and the public.”  (Journal of Aquatic Food Product Technology, 25 December 2013)
