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.

Available in PDF, EPUB and Kindle. Book excerpt: It is usually the case that scientists examine either ecological systems or social systems, yet the need for an interdisciplinary approach to the problems of environmental management and sustainable development is becoming increasingly obvious. Developed under the auspices of the Beijer Institute in Stockholm, this new book analyses social and ecological linkages in selected ecosystems using an international and interdisciplinary case study approach. The chapters provide detailed information on a variety of management practices for dealing with environmental change. Taken as a whole, the book will contribute to the greater understanding of essential social responses to changes in ecosystems, including the generation, accumulation and transmission of ecological knowledge, structure and dynamics of institutions, and the cultural values underlying these responses. A set of new (or rediscovered) principles for sustainable ecosystem management is also presented. Linking Social and Ecological Systems will be of value to natural and social scientists interested in sustainability.

Download or read book Conflicted Colony written by Kurt Korneski and published by McGill-Queen's Press - MQUP. This book was released on 2016-10-01 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nineteenth-century Newfoundland was an archetypal borderland - a space where changes in the authority of imperial, national, and indigenous territorial claims shaped the opportunities and identities of a socially diverse population. Conflicted Colony elucidates processes of state formation in Newfoundland through a reassessment of key moments in the country's history. Kurt Korneski closely examines five conflicts from the late nineteenth century - the Fortune Bay Dispute of 1878, the St George's Bay Dispute of 1889-92, the 1890s Lobster Controversy, the Battle of Foxtrap, and disputes over salmon grounds in Hamilton Inlet, Labrador - to explain how local regimes received, challenged, and reworked formal and informal diplomatic and commercial arrangements, as well as policies set out by the colonial and imperial government. The chapters examine antagonisms and divisions that grew out of clashes between the distinct commercial and social identities of regions in the borderlands and the sensibilities of merchants, politicians, and working people on the Avalon Peninsula. Providing new insight into the social history of Newfoundland and Labrador, these disputes illuminate contending perspectives driven by informal systems of governance, political movements, and local economic, social, demographic, and ecological circumstances. Conflicted Colony broadens, deepens, and clarifies our understanding of how Newfoundland became an integrated Dominion in the British Empire.

This book was released on 1999 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Describes a survey conducted in Placentia Bay in 1997 and 1998 to identify which physical and biotic factors may be associated with strong year classes of cod, and to identify important nursery sites in the bay. Results are presented on the distribution and size of 0- and 1-group cod catches throughout the bay in the two study years. The distribution and relative abundance are compared among sites and between years. A prediction is made of the relative strength of the 1996, 1997, and 1998 year-classes for Placentia Bay cod.

Download or read book Exploitation Rates and Population Size of Cod in Placentia Bay Subdivision 3Ps written by John Brattey and published by . This book was released on 1998 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper describes findings of a new mark-recapture study initiated in 1997. This study was designed to provide estimates of the exploitation rates on sub-components of the 3Ps cod stock, and in this paper we focus on the components of the stock inhabiting Placentia Bay. The study includes methods to estimate tag reporting rate, short-term tagging mortality, and short-term and long-term tag loss. We also develop a model that uses information on commercial catches and tag returns over time to estimate (1) overall exploitation rates on Placentia Bay cod associated with commercial fishing activity during 1997, and (2) population size of cod in Placentia Bay prior to the reopening of the commercial fishery in 1997.

Available in PDF, EPUB and Kindle. Book excerpt: This document summarizes scientific information used to determine the status of the cod stock in NAFO Subdivision 3Ps off the south coast of Newfoundland on 1 January 1999 and evaluates alternative TAC options for 1999. The current population biomass is estimated to be 250,000 t and the spawner biomass is estimated to be 145,000 t. The increase in spawning stock in recent years is due to the growth, maturation and good survival of the 1989 and 1990 year classes over the moratorium period, a strong 1992 year class, as well as reduction in age at maturity. Mixing of northern Gulf (3Pn, 4RS) cod with 3Ps cod in the Burego Bank-Hermitage Channel area of 3Ps during winter continues to present problems. This area was closed to directed cod fishing in the winter of 1998-1999; significant landings from this area during winter could have detrimental effects on the recovery of the neighbouring 3Pn, 4RS stock.
