摘要

Daniel Pauly is a pioneer of bold new methods for the assessment of marine ecosystems. His methods for estimating natural mortality rates, for interpreting length-frequency distributions and for quantifying energy pathways in marine food webs were all highly controversial when they were introduced, but are now accepted as providing useful rough and ready approximations to reality. In this new book, Pauly and co-author Jay Maclean report the results of another, even bolder, venture: an attempt to undertake a holistic assessment of the state of fisheries and ecosystems in the whole of the north Atlantic Ocean. This work has been carried out as part of the "Sea Around Us Project" (see www.saup.fisheries.ubc.ca), a programme based at the University of British Columbia that involves an international team of researchers and reviewers. In a Perfect Ocean provides an account of this work for a general audience, to supplement several publications in the professional literature. It includes a good historical review of the marine resources (especially the fish stocks) of the north Atlantic, but the centrepiece is the analysis of their decline as a result of exploitation, mostly during the twentieth century.
