Download or read book Deep Water Fisheries of the North Atlantic Oceanic Slope written by Alan G. Hopper and published by Springer Science & Business Media. 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.
Download or read book Age Determination Methods for Fishes Studied by the Groundfish Program at the Pacific Biological Station written by D. E. Chilton and published by Government of Canada, Fisheries and Oceans, Scientific Information and Publications Branch. This book was released on 1982 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: This manual describes methods and equipment used to estimate the ages of groundfish species studied by the Pacific Biological Station. Procedures for routine identification of annuli on scales, otoliths, otolith section, fin-ray sections, and spines are described and illustrated. Although the techniques are applied to species found off Canada's west coast, they should be applicable to other marine and freshwater fishes from temperate and arctic waters. Because some of the procedures are experimental and many have not been validated, it is expected that this manual will be revised several times.

Download or read book Age Determination Manual of the Alaska Fisheries Science Center Age and Growth Program written by Mary Elizabeth Matta and published by . This book was released on 2012 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Age and Growth Program at the Alaska Fisheries Science Center is tasked with providing age data in order to improve the basic understanding of the ecology and fisheries dynamics of Alaskan fish species. The primary focus of the Age and Growth Program is to estimate ages from otoliths and other calcified structures for age-structured modeling of commercially exploited stocks; however, the program has recently expanded its interests to include numerous studies on topics ranging from age estimate validation to the growth and life-history of non-target species. Because so many applications rely upon age data and particularly upon assurances as to their accuracy and precision, the Age and Growth Program has developed this practical guide to document the age determination of key groundfish species from Alaskan waters. The main objective of this manual is to describe techniques specific to the age determination of commercially and ecologically important species studied by the Age and Growth Program. The manual also provides general background information on otolith morphology, dissection, and preparation, as well as descriptions of methods used to measure precision and accuracy of age estimates. This manual is intended not only as a reference for age readers at the AFSC and other laboratories, but also to give insight into the quality of age estimates to scientists who routinely use such data.
Download or read book Overview of World Elasmobranch Fisheries written by Ramón Bonfil and published by Food & Agriculture Org.. This book was released on 1994 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: Major world fisheries for elasmobranchs are described in regard to their importance, recent trends, problems for assessment and management, conservation and the outlook for their sustainability. The analysis considers trends and outlooks in FAO's statistical areas, individual accounts of fisheries by the major elasmobranch fishing nations and the high seas fisheries that have significant by catches of elasmobranchs. Information on species, gears, patterns of exploitation, research and management of elasmobranchs is summarized for each of these countries. The general problems in appraising and managing elasmobranch fisheries and the need for conservation are discussed and possible solutions for some of these problems are proposed.

This book was released on 2007-04-05 with total page 213 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume offers a collection of papers on the quantitative assessment of age and growth in Chondrichthyan fishes. It details new hard parts for assessments of age, such as caudal thorns; new techniques like bomb radiocarbon for validation; and reexaminations of previous age and growth models. It also examines the importance of assessing the precision and accuracy of statistical formulas, analyses, and models used in age and growth studies.

Download or read book The Archaeologist s Laboratory written by Edward B. Banning and published by Springer Nature. This book was released on 2020-07-27 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: This second edition of the classic textbook, The Archaeologist’s Laboratory, is a substantially revised work that offers updated information on the archaeological work that follows fieldwork, such as the processing and analysis of artifacts and other evidence. An overarching theme of this edition is the quality and validity of archaeological arguments and the data we use to support them. The book introduces many of the laboratory activities that archaeologists carry out and the ways we can present research results, including graphs and artifact illustrations. Part I introduces general topics concerning measurement error, data quality, research design, typology, probability and databases. It also includes data presentation, basic artifact conservation, and laboratory safety. Part II offers brief surveys of the analysis of lithics and ground stone, pottery, metal artifacts, bone and shell artifacts, animal and plant remains, and sediments, as well as dating by stratigraphy, seriation and chronometric methods. It concludes with a chapter on archaeological illustration and publication. A new feature of the book is illustration of concepts through case studies from around the world and from the Palaeolithic to historical archaeology.The text is appropriate for senior undergraduate students and will also serve as a useful reference for graduate students and professional archaeologists.
