This book was released on 2019-04-15 with total page 131 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report covers historical aspects of the regional development of orange roughy fisheries, biology, stock assessment, ecosystem interactions, and key management issues. In light of debate regarding the sustainability of orange roughy fisheries, as well as fisheries for other long-lived deepwater species, this review describes how, by making the right choices and employing the best science available, there are now some demonstrably sustainable orange roughy fisheries. However, there remain considerable challenges. These include improving understanding of deepwater benthic communities in general, their genetics and population distributions, their dispersal, and their ability to recover from fishery-related and other impacts. With regard to the direct management of the fisheries, the report emphasizes important opportunities and needs to improve ageing and acoustic biomass estimation, and to better understand the genetics and population structure of the stocks of orange roughy that are fished and managed.

This book was released on 1995-08-31 with total page 940 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive review of current knowledge of the deep-water fishes of the North Atlantic and their exploitation. Individual countries and research institutions have carried out their own investigations and surveys in the past, but these results have rarely been coordinated, nor has there been a proper sharing of results and data. But there is a need to assess the total size of the deep-water stocks and the extent to which they can safely be exploited. The book also contains a number of papers describing present and past research and the present exploitation of resources, together with papers on the technical problems encountered in capturing and processing these fishes. An assessment of the requirements for future research is presented.

Available in PDF, EPUB and Kindle. Book excerpt: Tree-ring dating (dendrochronology) is a method of scientific dating based on the analysis of tree-ring growth patterns. As author James Speer notes, trees are remarkable bioindicators. Although there are other scientific means of dating climatic and environmental events, dendrochronology provides the most reliable of all paleorecords. Dendrochronology can be applied to very old trees to provide long-term records of past temperature, rainfall, fire, insect outbreaks, landslides, hurricanes, and ice storms--to name only a few events. This comprehensive text addresses all of the subjects that a reader who is new to the field will need to know and will be a welcome reference for practitioners at all levels. It includes a history of the discipline, biological and ecological background, principles of the field, basic scientific information on the structure and growth of trees, the complete range of dendrochronology methods, and a full description of each of the relevant subdisciplines. Individual chapters address the composition of wood, methods of field and laboratory study, dendroarchaeology, dendroclimatology, dendroecology, dendrogeomorphology, and dendrochemistry. The book also provides thorough introductions to common computer programs and methods of statistical analysis. In the final chapter, the author describes "frontiers in dendrochronology," with an eye toward future directions in the field. He concludes with several useful appendixes, including a listing of tree and shrub species that have been used successfully by dendrochronologists. Throughout, photographs and illustrations visually represent the state of knowledge in the field.

This book was released on 2009-08-07 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: Techniques and theory for processing otoliths from tropical marine fish have developed only recently due to an historic misconception that these organisms could not be aged. Otoliths are the most commonly used structures from which daily, seasonal or annual records of a fish’s environmental history are inferred, and are also used as indicators of migration patterns, home range, spatial distribution, stock structure and life history events. A large proportion of projects undertaken on tropical marine organisms involve removal and processing of calcified structures such as otoliths, statoliths or vertebrae to retrieve biological, biochemical or genetic information. Current techniques and principles have evolved rapidly and are under constant modification and these differ among laboratories, and more particularly among species and within life history stages. Tropical fish otoliths: Information for assessment, management and ecology is a comprehensive description of the current status of knowledge about otoliths in the tropics. This book has contributions from leading experts in the field, encompassing a tropical perspective on daily and annual ageing in fish and invertebrates, microchemistry, interpreting otolith microstructure and using it to back-calculate life history events, and includes a treatise on the significance of validating periodicity in otoliths.
