Book Description
The realization that many of the surveys which have been done in the past achieved little in relation to what could potentially have been gained, stimulated FAO to publish a series of manuals on resource surveys (Alverson 1971, Mackett 1973, Gulland 1975) which have set out ways of improving the quality of the data obtained from such surveys. However, there have been major advances in fisheries science since the earlier of these manuals was written, and accordingly it was decided, in 1976, that they should be updated and incorporated into a single volume covering all the major aspects of resource surveys.

Book Description
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.
