Deep Sea Demersal Fish And Fisheries

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.

A comprehensive account of deep-sea fishes, covering evolution, ecology and the potential threats posed by the growing fishing industry.

The technological advances of the last twenty years have brought huge advances in our understanding of the deep sea and of the species inhabiting this elusive and fascinating environment. Synthesising the very latest research and discoveries, this is a comprehensive and much-needed account of deep-sea fishes. Priede examines all aspects of this incredibly diverse group of animals, reviewing almost 3,500 species and covering deep-sea fish evolution, physiology and ecology as well as charting the history of their discovery from the eighteenth century to the present day. Providing a global account of both pelagic and demersal species, the book ultimately considers the effect of the growing deep-sea fishing industry on sustainability. Copiously illustrated with explanations of the deep-sea environment, drawings of fishes and information on how they adapt to the deep, this is an essential resource for biologists, conservationists, fishery managers and anyone interested in marine evolution and natural history.

The Law of the Seabed reviews the most pressing legal questions raised by the use and protection of natural resources on and underneath the world’s seabeds. While barely accessible, the seabed plays a major role in the Earth’s ecological balance. It is both a medium and a resource, and is central to the blue economy. New uses and new knowledge about seabed ecosystems, and the risks of disputes due to competing interests, urge reflection on which regulatory approaches to pursue. The regulation of ocean activities is essentially sector-based, and the book puts in parallel the international and national regimes for seabed mining, oil and gas, energy generation, bottom fisheries, marine genetic resources, carbon sequestration and maritime security operations, both within and beyond the national jurisdiction. The book contains seven parts respectively addressing the definition of the seabed from a multidisciplinary perspective, the principles of jurisdiction delimitation under the United Nations Convention on the Law of the Sea (UNCLOS), the regimes for use of non-living, living and marine biodiversity resources, the role of state and non-state actors, the laying and removal of installations, the principles for sustainable and equitable use (common heritage of mankind, precaution, benefit sharing), and management tools to ensure coexistence between activities as well as the protection of the marine environment.

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.

The deep ocean is home to some of the most unusual of all fishes. This book is the first Fish Physiology volume devoted to these bizarre undersea creatures. Practically every organ system is affected by the constraints imposed by benthic pressure, the absence of light, and the relatively scarce supply of both food and mates. Deep Sea Fishes demonstrates how these fishes living in extremely harsh conditions metabolize, behave, and evolve.

Includes the keynote addresses and papers presented on the conference themes that covered: environment, ecosystem biology, habitat, diversity and oceanography; population biology and resource assessment; harvesting and conservation strategies for resource management; technology requirements; monitoring, compliance and controls; a review of existing policies and instruments; and governance and management. It also provides the perspectives of participating experts and the conference Steering Committee. The general conclusions of the conference contain the elements that must be addressed and undertaken if deep-sea fish resources are to be sustained and their habitat protected to ensure productivity and safeguard deep-sea biodiversity. The second volume of the proceedings includes posters and corresponding papers presented at the conference as well as papers from workshops held prior to the main conference.
