This book was released on 1997 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: Presents findings of the Fisheries & Oceans Canada Maturity Working Group, assigned the task of developing long-term trends in age and length at sexual maturity for several principal Atlantic Zone stocks of Gadidae (cod, haddock, pollock). Implications of the results for application to fishery science and related conservation issues are discussed, and research recommendations are made to support new initiatives that would assist in maintaining the maturity time series for these fish stocks.

Available in PDF, EPUB and Kindle. Book excerpt: This edited volume collects population and metapopulation models for a wide variety of species, focusing on the use of models in population-level risk assessment for toxins. Each chapter of Demographic Toxicity describes the application of a population model to one species, with the aim of demonstrating how various life history characteristics of the species are incorporated into the model, how ecotoxicological impacts are modeled, and how the results of the model has been or can be used in risk assessment. The model in each chapter is implemented in RAMAS software, which uses matrix modeling of population dynamics. RAMAS software is believed to be the most powerful tool ever invented for this task.Demographic Toxicity includes a CD that contains a demo version of the program and the data files for each species. The book explains how to use these specific tools for modeling, analysis, and interpretation of data. Demographic Toxicity provides a major review of current knowledge on population dynamics in different species, representing both terrestrial and aquatic environments.

Available in PDF, EPUB and Kindle. Book excerpt: "The economic importance of fishes and their societal and culturalrelevance provide powerful incentives for large-scale, sustainedstudies of their dynamics" —the Editors The overall goal of this book is to give a picture of thepresent use of information on fish reproductive biology inassessment and management and its potential for improvingmanagement of these resources. Compiled by an international team of authors, each an expert intheir field, this exceptional volume is divided into three majorsections: Biology, population dynamics, and recruitment Information critical to successful assessment andmanagement Incorporation of reproductive biology and recruitmentconsiderations into management advice and strategies Including over 100 diagrams, this book is essential reading forall fisheries scientists. Libraries in universities and researchestablishments where this subject is studied and taught should havecopies on their shelves. "As one author put it: the goal is to facilitate a 'dialoguebetween assessment scientists and biologists.' Readers of anyspecialty should accept this challenge, and this book is anexcellent resource to aid them." —Fisheries, March 2010

Book excerpt: The Northeast Fisheries Science Center presents the section of "Age Determination Methods for Northwest Atlantic Species," on Atlantic cod, Gadus morhua, by J. Penttila. A major problem in age determination of cod is distinguishing between the settling check and the first annulus. Migration pattern indicate movement toward the south and west in winter and early spring and towards the north and east in late spring and summer.
Download or read book Atlantic Cod written by George A. Rose and published by John Wiley & Sons. This book was released on 2019-02-26 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive handbook, covering all aspects of the Atlantic cod including the biology, ecology, life histories, behaviour, commercial exploitation and conservation Not only is Atlantic cod one of the most valuable food fish in the world’s oceans, it is an important component of North Atlantic ecosystems and has been subject to much research into its biology, ecology and exploitation. After hundreds of years of exploitation, overfishing in the last half of the 20th Century caused many stocks to collapse, most famously the Northern cod stock off Newfoundland and Labrador, Canada. Since then, most cod stocks have been better researched and managed, but remain in a variety of states, from fully recovered to continued decline. This book, written by world experts, describes that research and management, and the importance of cod and its fisheries on North Atlantic cultures and economies, with impacts well beyond the range of the species. Atlantic Cod: Bio-Ecology of the Fish offers insightful chapter coverage of cod nomenclature, taxonomy, phylogeny and morphology; physiology and ecophysiology; reproduction and spawning behavior; early life history and pre-recruitment processes; migrations, movements and stock identity; feeding, growth and energetics; the place of cod in the ecosystem; the exploitation of cod through history and present day commercial fisheries and precautionary management for sustainable fisheries; impacts of climate change on cod biology and ecology; and the future of the species and its fisheries. Discusses the major commercial importance of Atlantic cod through history Provides a comprehensive treatment of the bio-ecology of the most researched and highly exploited fully marine species Examines how the decline (and recovery) of cod stocks is of great political and scientific interest An essential purchase for marine fisheries scientists Atlantic Cod: Bio-Ecology of the Fish is a vital book for all fisheries scientists, managers and fish biologists.
