Book Synopsis Biology and Ecology of Antarctic Krill by : Volker Siegel
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 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.

Book Synopsis Krill Fisheries of the World by : Stephen Nicol
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.

Book Synopsis Antarctic Ocean and Resources Variability by : Dietrich Sahrhage
Download or read book Antarctic Ocean and Resources Variability written by Dietrich Sahrhage and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the intensification of research activities in the Southern Ocean in recent years, both at national levels and through international cooperation in such projects as BIOMASS with its FIBEX and SIBEX phases, the need was felt increasingly for closer collaboration between biologists, meteorologists, and oceanographers in the study of the interaction between the atmospheric forces, the water masses, and the living resources. Better knowledge in this regard is not only of scientific interest but also of practical importance, especially for the management of the resources and the protection of the Antarctic marine ecosystem. As a follow-up on a recommendation by the IOC Program Group for the Southern Oceans made in March 1983, the Intergovernmental Oceanographic Commission organized a meeting of experts on oceanography related to the dynamics of the Antarctic ecosystems. During this meeting, held in Kiel, Federal Republic of Ger many, in May 1984, biologists and oceanographers involved in BIOMASS activities met with the oceanographers of SCOR Working Group 74 to discuss ways and means for additional physical and chemical observations in the oceanographic research within BIOMASS. It was the time when large fluctuations in the distribution of krill with subsequent detrimental effects on predator species dependent on krill had just been observed, and the question arose whether this was possibly the result of changes in the Antarctic water circulation.
Book Synopsis Seasonal, Physiological and Genetic Functions in Antarctic Krill, Euphausia Superba, at Different Latitudes in the Southern Ocean by : Flavia Höring

This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Light regime and the endogenous timing system of Antarctic krill, Euphausia superba, are known to play important roles in the regulation of its seasonal cycles of growth, maturity, metabolic activity and gene expression. This dissertation aimed to investigate the effect of different latitudinal light regimes on the seasonal cycle of Antarctic krill. It comprised two main parts: a) a field study with the goal to characterize seasonal processes on the molecular level in Antarctic krill in different latitudinal regions (Publication 1), and b) a two-year laboratory study under constant food and temperature conditions that tested the effect of the latitudinal light regimes 52¡S, and 66¡S, and constant darkness on the seasonal cycle of Antarctic krill (Publication 2 & 3). Our results suggest that the seasonal timing system of Antarctic krill is highly plastic, thereby promoting regional acclimatization to different latitudinal light regimes. We further discuss that the internal 'photoperiodic-controlled' seasonal cycles in Antarctic krill may be adjusted by other environmental cues like temperature and food supply in the field. engl.

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.
