"The Groundfish Analysis Investigation of the Tiburon Laboratory conducts an annual survey of age-0 rockfish (Genus Sebastes). A major long-term goal of these surveys is to estimate the strength of a year class based on their abundance at age 0. This requires that a positive relationship between recruitment to the fishery and age-0 abundance be established. In this report we examine the statistical power for establishing such a relationship."--p.ii

This important and exciting title represents the first authoritative volume focussed on pelagic (open ocean) sharks as a group. Virtually every pelagic shark expert in the world has contributed to this landmark publication which includes the latest data and knowledge on pelagic shark biology, fisheries, management, and conservation. Pelagic sharks face unprecedented levels of exploitation in all the world's oceans through both direct fisheries and by-catch, and effective management for these species is contingent upon solid science and data, which this book brings together for the first time. All those involved in shark biology will need to have a copy of this book.
