In a Perfect Ocean: The State of Fisheries and Ecosystems in the North Atlantic Ocean

Description

Recent decades have been marked by the decline or collapse of one fishery after another around the world, from swordfish in the North Atlantic to orange roughy in the South Pacific. While the effects of a collapse on local economies and fishing-dependent communities have generated much discussion, little attention has been paid to its impacts on the overall health of the ocean's ecosystems.
In a Perfect Ocean: The State of Fisheries and Ecosystems in the North Atlantic Ocean presents the first empirical assessment of the status of ecosystems in the North Atlantic ocean. Drawing on a wide range of studies including original research conducted for this volume, the authors analyze 14 large marine ecosystems to provide an indisputable picture of an ocean whose ecology has been dramatically altered, resulting in a phenomenon described by the authors as "fishing down the food web." The book:
* provides a snapshot of the past health of the North Atlantic and compares it to its present status
* presents a rigorous scientific assessment based on the key criteria of fisheries catches, biomass, and trophic level
* considers the factors that have led to the current situation
* describes the policy options available for halting the decline
* offers recommendations for restoring the North Atlantic
An original and powerful series of maps and charts illustrate where the effects of overfishing are the most pronounced and highlight the interactions among various factors contributing to the overall decline of the North Atlantic's ecosystems.
