Product Description
Reef ecosystems extend throughout the tropics. Exploited bysmall-scale fishers, reefs supply food for millions of people, but,worldwide, there are growing worries about the productivity andcurrent state of these ecosystems. Reef fish stocks display manyfeatures of fisheries elsewhere. However, habitat spatial complexity,biological diversity within and among species, ecosystem intricacyand variable means of exploitation make it hard to predictsustainable modes and levels of fishing. ...

Product Description
Expanded and updated, this second edition considers fish diseases in the context of the fish's environment, and includes coverage of many aspects of microbiology. The authors provide information on the structure of fish in order to help familiarize readers with general fish anatomy. All the bacterial taxa which have been reported as fish pathogens are included, and the material is subdivided for easy reference into sections which deal with characteristics of the diseases, isolation methods, characterization of the pathogens, diagnosis, epizootilogy, pathogenicity mechanisms and control.

Written by bacteriologists for microbiologists, the book tabulates the identification procedures, and gives characteristics of pathogens, the diseases and their control. As farmed fish are of greater commercial importance, and the consequences of losses attributable to bacterial fish pathogens therefore of greater economic consequence, the authors concentrate on these rather than on wild stocks. ...

Product 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.
