Available in PDF, EPUB and Kindle. Book excerpt: "Makes you feel as if you're part of an engaging dinnertime conversation." --Science News Krill. It's a familiar word that conjures oceans, whales, and swimming crustaceans. Scientists say they are one of most abundant animals on the planet. But few can accurately describe krill or explain their ecological importance. Eminent krill scientist Stephen Nicol wants us to know more about these enigmatic creatures and how we can protect them as Antarctic ice melts. This engaging account takes us to the Southern Ocean to learn firsthand the difficulties and rewards of studying krill in their habitat. From his early education about the sex lives of krill in the Bay of Fundy to a krill tattoo gone awry, Nicol uses humor and personal stories to bring the biology and beauty of krill alive.

Download or read book Krill written by Inigo Everson and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Krill written by Jonah Young and published by Ice Press. This book was released on 2015-01-06 with total page 79 pages. Available in PDF, EPUB and Kindle. Book excerpt: Note that this book is based on Wikipedia and other public domain resources. Krill are small crustaceans of the order Euphausiacea, and are found in all the world's oceans. The name krill comes from the Norwegian word krill, meaning "young fry of fish", which is also often attributed to other species of fish. Krill are considered an important trophic level connection – near the bottom of the food chain – because they feed on phytoplankton and to a lesser extent zooplankton, converting these into a form suitable for many larger animals for whom krill makes up the largest part of their diet. In the Southern Ocean, one species, the Antarctic krill, Euphausia superba, makes up an estimated biomass of around 379 million tons, more than that of humans. Of this, over half is eaten by whales, seals, penguins, squid and fish each year, and is replaced by growth and reproduction. Most krill species display large daily vertical migrations, thus providing food for predators near the surface at night and in deeper waters during the day.

Download or read book Biology and Ecology of Antarctic Krill written by Volker Siegel and published by Springer. This book was released on 2016-08-03 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book gives a unique insight into the current knowledge of krill population dynamics including distribution, biomass, production, recruitment, growth and mortality rates. Detailed analysis is provided on food and feeding, reproduction and krill behaviour. The volume provides an overview on the aspects of natural challenges to the species, which involve predation, parasites and the commercial exploitation of the resource and its management. A chapter on genetics shows the results of population subdivision and summarizes recent work on sequencing transcriptomes for studying gene function as part of the physiology of live krill. The focus of Chapter 4 is on physiological functions such as biochemical composition, metabolic activity and growth change with ontogeny and season; and will demonstrate which environmental factors are the main drivers for variability. Further discussed in this chapter are the bottle necks which occur in the annual life cycle of krill, and the mechanisms krill have adapted to cope with severe environmental condition.

Download or read book Krill Fisheries of the World written by Stephen Nicol and published by Food & Agriculture Org.. This book was released on 1997 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
