Krill Fisheries of the World


Book Description

Euphausiids, or krill, have been harvested since at least the 19th century and possibly earlier (Fisher et al. 1953). It is, however, only in the last 50 years that large scale commercial harvesting of krill has occurred. Despite the widespread distribution of euphausiids throughout the oceans of the world and their undoubted abundance, they have only been harvested in large quantities in two areas - in Antarctic waters and in the coastal waters off Japan. There are, however, experimental or small-scale krill fisheries in other areas and there has been speculation about the potential for such fisheries in still further areas. This report summarises the available knowledge about the existing fisheries and draws together information on other species of euphausiids that have been thought to have commercial potential. A number of other reports have been written on the commercial potential of krill, particularly Antarctic krill (Budzinski et al. 1985; Eddie 1977; Everson 1977; Grantham 1977). Another relatively recent review (Neal and Maris 1985) asessed the harvest of krill in the context of fisheries biology of other shrimps and shrimp-like animals. This report provides additional material to that provided in these reports but no attempt has been made to summarise their content except where it is necessary to understand new developments. Much of the information on the fisheries for Euphausia pacifica is published in Japanese or is published in reports of fisheries agencies. For this reason, the biology of, and the fisheries on, this species are dealt with in some detail utilising these information sources which have not previously been readily available.




Climate Change Impacts on Fisheries and Aquaculture


Book Description

The first comprehensive review of the current and future effects of climate change on the world’s fisheries and aquaculture operations The first book of its kind, Climate Change Impacts on Fisheries and Aquaculture explores the impacts of climate change on global fisheries resources and on marine aquaculture. It also offers expert suggestions on possible adaptations to reduce those impacts. The world's climate is changing more rapidly than scientists had envisioned just a few years ago, and the potential impact of climate change on world food production is quite alarming. Nowhere is the sense of alarm more keenly felt than among those who study the warming of the world's oceans. Evidence of the dire effects of climate change on fisheries and fish farming has now mounted to such an extent that the need for a book such as this has become urgent. A landmark publication devoted exclusively to how climate change is affecting and is likely to affect commercially vital fisheries and aquaculture operations globally, Climate Change Impacts on Fisheries and Aquaculture provides scientists and fishery managers with a summary of and reference point for information on the subject which has been gathered thus far. Covers an array of critical topics and assesses reviews of climate change impacts on fisheries and aquaculture from many countries, including Japan, Mexico, South Africa, Australia, Chile, US, UK, New Zealand, Pacific Islands, India and others Features chapters on the effects of climate change on pelagic species, cod, lobsters, plankton, macroalgae, seagrasses and coral reefs Reviews the spread of diseases, economic and social impacts, marine aquaculture and adaptation in aquaculture under climate change Includes special reports on the Antarctic Ocean, the Caribbean Sea, the Arctic Ocean and the Mediterranean Sea Extensive references throughout the book make this volume both a comprehensive text for general study and a reference/guide to further research for fisheries scientists, fisheries managers, aquaculture personnel, climate change specialists, aquatic invertebrate and vertebrate biologists, physiologists, marine biologists, economists, environmentalist biologists and planners.




Southern Ocean Ecology


Book Description

BIOMASS (Biological Investigations of Marine Antarctic Systems and Stocks) was a unique, large-scale, long-term, international research programme established in 1977 to investigate the ecology of the Southern Ocean. Its main aim was to gain a greater understanding of the biological systems and stocks in the marine Antarctic environment, thereby providing a sound basis for the future management of the living resources within this immense ocean. The programme was drawn to a close in 1991 and its completion marked by a colloquium which brought together key researchers to summarise and review the results obtained. This volume, arising from that colloquium, provides a succinct, state-of-the-art account of the ecology of the Southern Ocean and serves as a comprehensive record of this unique and successful international project.




Non-Flag State Enforcement in High Seas Fisheries


Book Description

This book is the first comprehensive examination of state practice relating to enforcement by non-flag states of the high seas conservation and management measures adopted by Regional Fisheries Organisations. It demonstrates that an exception is emerging in customary international law to the rule of the primacy of flag state jurisdiction in the high seas fisheries context.




The Utilization of Krill


Book Description

Discusses biochemistry, processing, marketing and nutritional value of the antarctic krill, the shrimp-like crustacean sought as a new protein source.

Krill


Book Description

Krill, or euphausiids, a group of immense importance in marine ecosystems, comprises over 80 species, most of which are planktonic. Krill are widespread with species to be found in all the oceans of the world. Their numerical density in some regions increases their importance to marine ecosystems and has led to commercially successful krill harvesting. This comprehensive volume, thoroughly edited by Inigo Everson, well known for his work in this area, comprises chapters written by internationally acknowledged experts. The contents include coverage of: sampling and distribution, population, aggregation, reproduction and the role of krill in the ecosystem. Further specific chapters include krill harvesting, products and details of management in Japanese, Canadian and Southern Ocean waters. Drawing on the experience in each, the ecosystem approach to management is discussed in detail and how it might be applied more widely for example in forage fisheries. This most important volume draws together, for the first time, a vast amount of vital information for all those involved in work on these important marine organisms. Krill will be of great use to fisheries scientists, marine biologists and ecologists, oceanographers, zoologists and invertebrate biologists and all those involved in the commercial harvesting, exploitation and management of krill, world wide. Libraries in all aquatic and marine research stations and universities where marine and fisheries sciences are studied and taught should have multiple copies of this landmark publication on their shelves. Contributions from internationally-recognised experts in the field. Well-edited to provide an accessible and user-friendly book. Krill are a key part of ocean ecosystems. Part of exciting new Blackwell Science Series.
