Book Synopsis Arctic Climate Impact Assessment - Scientific Report by : Arctic Climate Impact Assessment
Download or read book Arctic Climate Impact Assessment - Scientific Report written by Arctic Climate Impact Assessment and published by Cambridge University Press. This book was released on 2005-11-07 with total page 1053 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Arctic is now experiencing some of the most rapid and severe climate change on earth. Over the next 100 years, climate change is expected to accelerate, contributing to major physical, ecological, social, and economic changes, many of which have already begun. Changes in arctic climate will also affect the rest of the world through increased global warming and rising sea levels. Arctic Climate Impact Assessment was prepared by an international team of over 300 scientists, experts, and knowledgeable members of indigenous communities. The report has been thoroughly researched, is fully referenced, and provides the first comprehensive evaluation of arctic climate change, changes in ultraviolet radiation and their impacts for the region and for the world. It is illustrated in full color throughout. The results provided the scientific foundations for the ACIA synthesis report - Impacts of a Warming Arctic - published by Cambridge University Press in 2004.

Book Synopsis Effects of Temperature on the Growth of Arctic Charr Salvelinus Alpinus in Ungava and Labrador, Canada by : Alyssa D. Murdoch
Download or read book Effects of Temperature on the Growth of Arctic Charr Salvelinus Alpinus in Ungava and Labrador, Canada written by Alyssa D. Murdoch and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Arctic surface air temperatures have been warming at twice the global rate, making it one of the most susceptible regions to current climate change. Effects on cold-adapted aquatic species, such as the culturally and ecologically important Arctic charr (Salvelinus alpinus), are difficult to anticipate and may vary depending on site-specific attributes. Temperature has a direct influence on aspects of species' fitness, including growth, reproduction and, ultimately, survival. Previous research on temperature-growth patterns in Arctic charr has yielded variable results, particularly for studies observing these patterns in the wild. Two field-based studies are presented in this thesis, in an attempt to better understand temperature-growth patterns for wild populations of Arctic charr. In the first study, individual measurements of annual, or within-season growth were determined from tag-recaptured Arctic charr and examined in relation to summer sea surface temperatures and within-season capture timing in the Ungava and Labrador regions of eastern Canada. Differences in among-year growth were significant for Ungava Bay Arctic charr, with growth being positively correlated with temperature. Growth of Labrador Arctic charr did not vary significantly among years. Regional comparisons demonstrated that Ungava Arctic charr had significantly higher annual growth rates, with differences among years in all regions being positively correlated with temperature. Within-season growth rates of Labrador Arctic charr peaked in June, declined toward August, and were negatively correlated with the length of time spent at sea and mean experienced sea surface temperatures. A quadratic model relating growth rate to temperature best explained the pattern of within-season growth. The higher annual growth of Ungava Bay Arctic charr was attributed to the high sea surface temperatures experienced in 2010-11 and the localized differences in nearshore productivity as compared to Labrador. Results suggest that increases in water temperature may have profound consequences for Arctic charr growth in the Canadian sub-Arctic, depending on the responses of local marine productivity to those same temperature increases. In the second study, oxygen stable isotope temperature reconstruction methods were used to estimate mean experienced summer temperatures from growth zones within individual otoliths of Arctic charr sampled from contrasting lake environments. For either lake, otolith-estimated temperatures were not significantly related to back-calculated growth. Significant negative effects on back-calculated growth were observed due to increasing air temperatures in the smaller lake, owing to warmer surface waters and a limited amount of preferred cool-water habitat available. A similar relationship was not observed in the larger lake, indicating that the cooler, deeper lake provides ample preferred cool-water habitat for Arctic charr despite climate warming. In addition, young-of-the-year temperatures negatively related to zone 2 growth for the smaller lake, whereas no significant correlation was found for the larger lake. Results here provide evidence for differing climate-influenced growth outcomes depending on the site-specific fish density: preferred thermal habitat volume ratio as dictated by local attributes including lake morphometry, upstream catchment area and life-history strategy. Conclusions from this thesis include the increased need for detailed site- and population-specific assessments of the impacts of increasing temperatures on Arctic charr growth. Better understanding of the drivers of temperature-growth relationships in wild Arctic charr populations will facilitate more accurate stock forecasts with the overall goal of sustaining exploited Arctic charr populations as the climate warms and becomes increasingly variable.

Available in PDF, EPUB and Kindle. Book excerpt: Among the fishes. a remarkably wide range of biological adaptations to diverse habitats has evolved. As well as living in the conventional habitats of lakes. ponds, rivers, rock pools and the open sea, fish have solved the problems of life in deserts. in the deep sea. in the cold antarctic. and in warm waters of high alkalinity or of low oxygen. Along with these adaptations, we find the most impressive specialisations of morphology, physiology and behaviour. For example we can marvel at the high-speed swimming of the marlins. sailfish and warm-blooded tunas, air-breathing in catfish and lungfish. parental care in the mouth-brooding cichlids and viviparity in many sharks and toothcarps. Moreover, fish are of considerable importance to the survival of the human species in the form of nutritious. delicious and diverse food. Rational exploi management of our global stocks of fishes must rely upon a detailed tation and and precise insight of their biology. The Chapman [.,. Hall Fish and Fisheries series aims to present timely volumes reviewing important aspects of fish biology. Most volumes will be of interest to research workers in biology. zoology. ecology and physiology but an additional aim is for the books to be accessible to a wide spectrum of non-specialist readers ranging from undergraduates and postgraduates to those with an interest in industrial and commercial aspects of IIsh and t1sheries.

Book excerpt: Over the past few years, it has become more and more obvious that fish farming will become increasingly important in the future. As fish farming moves into its industrial phase, technology will be an important factor in determining its successful development. It is therefore important for scientists & representatives from the aquaculture industry to meet to define state of the art and explore future development of fish farming technology for different fish species. 81 papers and abstracts were presented at the conference. The proceedings reflect the different sections of the conference: the plenum sessions and three parallel sessions: Juvenile marine fish, open production plants, closed production plants and poster sessions.
Book Synopsis Food Intake in Fish by : Dominic Houlihan
Download or read book Food Intake in Fish written by Dominic Houlihan and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: The intake of food by fishes is an area of study that is of great importance to the applied sciences of fisheries and aquaculture for a number of reasons. For example a thorough knowledge of factors influencing the ingestion of feed can lead to successful manipulation of the rearing environment of cultured fishes, thereby ensuring improved growth performance and feed utilisation, and decreasing the amount of waste (and consequent pollution) per unit of fish produced. This important book, which has arisen out of a European Union COST programme, illustrates how insights into the biological and environmental factors that underlie the feeding responses of fish may be used to address practical issues of feed management. Food Intake in Fish contains carefully edited contributions from internationally recognised scientists, providing a book that is an invaluable tool and reference to all those involved in aquaculture, especially those working in the aquaculture feed industry and scientific personnel in commercial and research aquaculture facilities. This book should also find a place on the shelves of fish biologists and physiologists and as a reference in libraries of universities, research establishments and aquaculture equipment companies.
Book Synopsis The Fish Production Potential of the Baltic Sea by : Lars Håkanson
Download or read book The Fish Production Potential of the Baltic Sea written by Lars Håkanson and published by Springer Science & Business Media. This book was released on 2010-06-25 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: It presents a new approach to set fish quota based on holistic ecosystem modeling (the CoastWeb-model) and also a plan to optimize a sustainable management of the Baltic Sea including a cost-benefit analysis. This plan accounts for the production of prey and predatory fish under different environmental conditions, professional fishing, recreational fishing and fish cage farm production plus an analysis of associated economic values. Several scenarios and remedial strategies for Baltic Sea management are discussed and an "optimal" strategy motivated and presented, which challenges the HELCOM strategy that was accepted by the Baltic States in November 2007. The strategy advocated in this book would create more than 7000 new jobs, the total value of the fish production would be about 1600 million euro per year plus 1000 million euro per year related to the willingness-to-pay to combat the present conditions in the Baltic Sea. Our strategy would cost about 370 million euro whereas the HELCOM strategy would cost about 3100 million euro per year. The "optimal" strategy is based on a defined goal - that the water clarity in the Gulf of Finland should return to what it was 100 years ago.
