Biology and Ecology of Antarctic Krill
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.
The Curious Life of Krill
"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.
Antarctic Ocean and Resources Variability
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...
Krill Fisheries of the World
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 ...
The Utilization of Krill
Discusses biochemistry, processing, marketing and nutritional value of the antarctic krill, the shrimp-like crustacean sought as a new protein source.
