Description
In an effort to encourage ecologically sound, sustainable fisheries management policies, this study explores the assessment of fish stock. New techniques which overcome many of the limitations of older methods are emphasized.
Commences with a discussion of biological and statistical considerations involved in designing an effective survey. Examines sampling equipment and techniques used in conducting direct surveys with equal attention to trawl, acoustic, ichthyoplankton and sighting studies. Alternative approaches used in each type of survey are reviewed and numerous case histories illustrate successful applications.
