Opis

Based on an international symposium and workshop hosted by the University of Hull International Fisheries Institute, this new reference includes expert reviews of the advantages and shortcomings of all current techniques and management strategies used in assessment of freshwater fish stocks worldwide. In addition to the core reports, overview papers present a summary of the current status of our knowledge in each of the major subject areas, with a final chapter appraising present and future perspectives on the concept of stock assessment. All contributions are fully illustrated and referenced.
Stock Assessment in Inland Fisheries is likely to become the international, standard reference for all fisheries departments--offering a single source of contemporary and definitive information. Moreover, it is also intended to serve as a course text for students learning about freshwater-fisheries management.

Blurb

Based on an international symposium and workshop to be hosted by the University of Hull International Fisheries Institute, this new reference includes expert reviews of the advantages and shortcomings of all current techniques and management strategies used in assessment of freshwater fish stocks, worldwide. Contributions to this new reference will address the following major areas: Survey Methods, Fisheries Statistics, Population Dynamics, Catch Effort Methods, Stock Assessment in Large Lakes, Stock Assessment in Large Rivers, Management of Freshwater Fish Stocks. In addition to the core reports, overview papers will present a summary of our current status of knowledge in each of the major subject areas, and a final chapter will offer an expert appraisal of present and future perspectives in relation to the concept of stock assessment. All contributions will be fully illustrated and referenced. Stock Assessment in Inland Fisheries will become the international, standard reference for all fisheries departments offering a single source of contemporary and definitive information. It is also intended that the book serve as a course text for all studying within the various areas of freshwater fisheries management.
