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 data-for example underreporting or changes in the likelihood that fish can be caught with a given type of gear-can seriously degrade the quality of stock assessments. The volume makes recommendations for means to improve stock assessments and their use in fishery management. 606 $aFish stock assessment$zUnited States 606 $aFishery management$zUnited States 615 0$aFish stock assessment 615 0$aFishery management 676 $a333.95/611 712 02$aNational Research Council (U.S.).$bCommittee on Fish Stock Assessment Methods. 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910970416003321 996 $aImproving fish stock assessments$94368279 997 $aUNINA
