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.
Download or read book Biology and Ecology of Atlantic Cod written by Nataliia Kulatska and published by CRC Press. This book was released on 2024-10-31 with total page 301 pages. Available in PDF, EPUB and Kindle. Book excerpt: Atlantic cod is an important fish species in human history and continues to be a major influence on North Atlantic fisheries management, as stock collapses and recoveries impact coastal communities and shelf sea food webs. This book provides an overview of Atlantic cod biology and ecology, focussing on regional differences in life-history and stock dynamics that affect productivity and the challenges faced by management. By comparing the success of management approaches and the local influence of changing climate and food webs, the book highlights the different pressures facing stocks and identifies knowledge gaps across the species’ range.

This book was released on 2016 with total page 576 pages. Available in PDF, EPUB and Kindle. Book excerpt: Atlantic cod (Gadus morhua) have been a principal target species in New England's ground fish fishery since the 17th century. In recent decades, the Gulf of Maine cod stock has experienced substantial declines in abundance, and many historical spawning components have been depleted, reducing stock productivity and stability. Managing stock rebuilding has been difficult because of many uncertainties in population dynamics. Therefore, to support stock rebuilding efforts, the objective of this dissertation was to improve our understanding of the spawning dynamics, seasonal movements, and population structure of Atlantic cod in the Gulf of Maine. An interdisciplinary review of the scientific literature demonstrated that the cod population off New England can be described as a metapopulation that includes genetically-distinct spring- and winter spawning subpopulations which are comprised of many finer-scale spawning components. Available information indicates that current management unit boundaries do not accurately represent the biological population structure. Therefore, a modification of current management units is recommended to provide a more accurate representation of the underlying biological population processes. Review of the cod spawning literature indicated that cod spawn in multiple locations and seasons, and the complex cod mating system can be described as a "lek". The aspects of cod spawning dynamics most important for consideration by fishery managers are the spatial and temporal extent ofspawning, the behavior of spawners, and the reproductive contributions of older age-classes. The application of spawning closures as part of a multidisciplinary approach to fisheries management is recommended to prevent disruption of spawning and extirpation of semi-discrete spawning components. Spawning site fidelity contributes to the formation and maintenance of the observed metapopulation structure and delays the recolonization of abandoned spawning sites by limiting reproductive connectivity. Acoustic telemetry was used to document prevalent, fine-scale spawning site fidelity with respect to an inshore spawning site in the western Gulf of Maine. Movements away from the inshore spawning site were studied using conventional tags, acoustic telemetry, and geolocation utilizing data from archival data storage tags. Connectivity was documented among multiple inshore spawning sites, which is apparently sufficient to promote gene flow within the western subpopulation. Cod were primarily residential within the western Gulf of Maine. After spawning inshore, cod moved to offshore feeding grounds from summer to early winter. Deep offshore basins served as overwintering habitat before initiation of an inshore spring spawning migration. Results from this dissertation have been valuable for informing fishery managers in the development of regulations to protect cod spawning aggregations. Findings are contributing to ongoing processes to investigate cod population structure and reevaluate current management units. This dissertation provides a more holistic understanding of cod population dynamics, which is expected to contribute to the development of future fishery management plans and stock assessment models that work towards achieving stock rebuilding.
Download or read book Fish Reproductive Biology written by Tore Jakobsen and published by John Wiley & Sons. This book was released on 2016-03-21 with total page 500 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fish recruitment is a key process for maintaining sustainable fish populations. In the marine environment, fish recruitment is carried out in many different ways, all of which have different life history strategies. The objective of this book is to argue for greater linkages between basic and applied research on fisheries recruitment, and assessment and management of exploited fish stocks. Following an introductory chapter, this second edition of Fish Reproductive Biology is organized into 3 main sections: Biology, Population Dynamics and Recruitment Information Critical to Successful Assessment and Management Incorporation of Reproductive Biology and Recruitment Considerations into Management Advice and Strategies The authors collectively bring a wide range of diverse experience in areas of reproductive biology, fisheries oceanography, stock assessment, and management. Fully updated throughout, the book will be of great interest to a wide audience. It is useful as a textbook in graduate and undergraduate courses in fisheries biology, fisheries science, and fisheries resource management and will provide vital information for fish biologists, fisheries scientists and managers.

Available in PDF, EPUB and Kindle. Book excerpt: This new edition of Biological Oceanography has been greatly updated and expanded since its initial publication in 2004. It presents current understanding of ocean ecology emphasizing the character of marine organisms from viruses to fish and worms, together with their significance to their habitats and to each other. The book initially emphasizes pelagic organisms and processes, but benthos, hydrothermal vents, climate-change effects, and fisheries all receive attention. The chapter on oceanic biomes has been greatly expanded and a new chapter reviewing approaches to pelagic food webs has been added. Throughout, the book has been revised to account for recent advances in this rapidly changing field. The increased importance of molecular genetic data across the field is evident in most of the chapters. As with the previous edition, the book is primarily written for senior undergraduate and graduate students of ocean ecology and professional marine ecologists.
