This book was released on 2019-04-15 with total page 131 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report covers historical aspects of the regional development of orange roughy fisheries, biology, stock assessment, ecosystem interactions, and key management issues. In light of debate regarding the sustainability of orange roughy fisheries, as well as fisheries for other long-lived deepwater species, this review describes how, by making the right choices and employing the best science available, there are now some demonstrably sustainable orange roughy fisheries. However, there remain considerable challenges. These include improving understanding of deepwater benthic communities in general, their genetics and population distributions, their dispersal, and their ability to recover from fishery-related and other impacts. With regard to the direct management of the fisheries, the report emphasizes important opportunities and needs to improve ageing and acoustic biomass estimation, and to better understand the genetics and population structure of the stocks of orange roughy that are fished and managed.

Available in PDF, EPUB and Kindle. Book excerpt: This book deals with the bottom-living fishes of the world's largest ecosystem, the deep-sea. After a brief review of the oceanographic setting, the diversity and ecology of this unique ichthyofauna are considered in detail. The book goes on to deal explicitly with slope fisheries, both developed and developing. The interaction of the ecology of the species involved (examples include orange roughy, grenadier, Greenland halibut and black scabbardfish) with fishing practices and management regimes is then discussed. An ecological framework for management is necessary for the resources to be sustainable it is argued, rather than simply extending approaches used on the Continental Shelf to the deep-sea.

This book was released on 1995-08-31 with total page 940 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive review of current knowledge of the deep-water fishes of the North Atlantic and their exploitation. Individual countries and research institutions have carried out their own investigations and surveys in the past, but these results have rarely been coordinated, nor has there been a proper sharing of results and data. But there is a need to assess the total size of the deep-water stocks and the extent to which they can safely be exploited. The book also contains a number of papers describing present and past research and the present exploitation of resources, together with papers on the technical problems encountered in capturing and processing these fishes. An assessment of the requirements for future research is presented.

Download or read book Thermodynamics and Ecological Modelling written by Sven E. Jorgensen and published by CRC Press. This book was released on 2018-10-03 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thermodynamics is used increasingly in ecology to understand the system properties of ecosystems because it is a basic science that describes energy transformation from a holistic view. In the last decade, many contributions to ecosystem theory based on thermodynamics have been published, therefore an important step toward integrating these theories and encouraging a more wide spread use of them is to present them in one volume. An ecosystem consists of interdependent living organisms that are also interdependent with their environment, all of which are involved in a constant transfer of energy and mass within a general state of equilibrium or dis-equilibrium. Thermodynamics can quantify exactly how "organized" or "disorganized" a system is - an extremely useful to know when trying to understand how a dynamic ecosystem is behaving. A part of the Environmental and Ecological (Math) Modeling series, Thermodynamics and Ecology is a book-length study - the first of its kind - of the current thinking on how an ecosystem can be explained and predicted in terms of its thermodynamical behavior. After the introductory chapters on the fundamentals of thermodynamics, the book explains how thermodynamic theory can be specifically applied to the "measurement" of an ecosystem, including the assessment of its state of entropy and enthalpy. Additionally, it will show economists how to put these theories to use when trying to quantify the movement of goods and services through another type of complex living system - a human society.

Download or read book Defying Ocean's End written by Linda Glover and published by Island Press. This book was released on 2012-09-26 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: If humankind were given a mandate to do everything in our power to undermine the earth's functioning, we could hardly do a better job than we have in the past thirty years on the world's oceans, both by what we are putting into it-millions of tons of trash and toxic materials-and by what we are taking out of it-millions of tons of wildlife. Yet only recently have we begun to understand the scale of those impacts. Defying Ocean's End is the result of an unprecedented effort among the world's largest environmental organizations, scientists, the business community, media, and international governments to address these marine issues. In June 2003, in the culmination of a year-long effort, they met specifically to develop a comprehensive and achievable agenda to reverse the decline in health of the world's oceans. As conservation organizations begin to expand their focus from land issues to include a major focus on preservation of the sea, it is increasingly apparent that we have to approach marine conservation differently and at much larger scale than we have to date. What's also clear is the magnitude and immediacy of the growing ocean concerns are such that no one organization can handle the job alone. Defying Ocean's End is a bold step in bringing the resources needed to bear on this vast problem before it is too late. It offers a broad strategy, a practical plan with priorities and costs, aimed at mobilizing the forces needed to bring about a "sea change" of favorable attitudes, actions, and outcomes for the oceans-and for all of us.

Download or read book Marine Fisheries Ecology written by Simon Jennings and published by John Wiley & Sons. This book was released on 2013-04-16 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: This topical and exciting textbook describes fisheries exploitation, biology, conservation and management, and reflects many recent and important changes in fisheries science. These include growing concerns about the environmental impacts of fisheries, the role of ecological interactions in determining population dynamics, and the incorporation of uncertainty and precautionary principles into management advice. The book draws upon examples from tropical, temperate and polar environments, and provides readers with a broad understanding of the biological, economic and social aspects of fisheries ecology and the interplay between them. As well as covering 'classical' fisheries science, the book focuses on contemporary issues such as industrial fishing, poverty and conflict in fishing communities, marine reserves, the effects of fishing on coral reefs and by-catches of mammals, seabirds and reptiles. The book is primarily written for students of fisheries science and marine ecology, but should also appeal to practicing fisheries scientists and those interested in conservation and the impacts of humans on the marine environment. particularly useful are the modelling chapters which explain the difficult maths involved in a user-friendly manner describes fisheries exploitation, conservation and management in tropical, temperate and polar environments broad coverage of 'clasical' fisheries science emphasis on new approaches to fisheries science and the ecosystem effects of fishing examples based on the latest research and drawn from authors' international experience comprehensively referenced throughout extensively illustrated with photographs and line drawings

Book excerpt: There's so much we don't know about what lies deep beneath the ocean's surface - and the time to find out is growing increasingly precious . . . Professor Alex Rogers is one of the world's leading experts in marine biology and oceanology, and has spent his life studying the deep ocean - and in particular the impact of human activity on the ecosystems of the oceans. In this timely, galvanising and fascinating book - replete with stunning photography of strange and beautiful creatures - Professor Rogers offers a fundamentally optimistic view of humanity's relationship with the oceans - and also a very personal account of his own interaction with the seas.
