<br> This book, intended as a text for advanced courses, is a synthesis of quantitative fish population models and methods for quantitative stock assessment. Broadly inclusive, the book covers a variety of methods and models and incorporates modern statistical concepts where appropriate. Proceedings from simple to complex, chapters cover population growth, mortality, and the fishing process (CPUE); stock productivity and surplus production; stock and recruitment; growth and fecundity; delay-difference models; age-structured models; catch-age and age-structured assessment methods; size-structured models and assessment methods; migration, movement, and spatiotemporal considerations; and optimal harvesting. --Fisheries<br> Why should a terrestrial ecologist be interested in a book on fish population dynamics, and especially a book on quantitative fish population dynamics? There are at least two compelling reasons. First, much of the foundational work in population ecology was motivated by
