This document provides a review, commentary and tabulations of the main trends that have occurred in exploitation of fisheries resources since the 1970s, largely as they are reflected in the FAO database on fishery landings, supplemented with selected information from the fishery literature. Reviews were prepared separately for the 15 main areas into which FAO divides the world's oceans for statistical purposes. They are then compared from a global perspective to reveal relative trends by species and areas, which are highlighted. Several special topics are reviewed, including tuna and tuna-like species, whales and dolphins, and environmental issues in fisheries.

Ocean harvests have plateaued worldwide and many important commercial stocks have been depleted. This has caused great concern among scientists, fishery managers, the fishing community, and the public. This book evaluates the major models used for estimating the size and structure of marine fish populations (stock assessments) and changes in populations over time. It demonstrates how problems that may occur in fisheries dataâ€"for example underreporting or changes in the likelihood that fish can be caught with a given type of gearâ€"can seriously degrade the quality of stock assessments. The volume makes recommendations for means to improve stock assessments and their use in fishery management.
