Download or read book A Numeric Scoring Matrix for Use in the Rapid Assessment of Extinction Vulnerability of Marine Fish Species in the NAFO Regions 4VWX 5Zc written by Terry L. Johnston and published by St. Andrews, N.B.. : Fisheries and Oceans Canada. This book was released on 2004 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Accord for the Protection of Species at Risk ( 1996) and the Species at Risk Act (2003) arc initiatives of the Federal government that were established to provide protection and recovery for species at risk in Canada. Fisheries and Oceans Canada (DFO) is the primary source of information and expertise concerning the assessment of extinction vulnerability of aquatic species. The Mari times Region of DFO is responsible for compiling biological information concerning status and potential extinction risk of marine fish species that support fisheries along the Scotian Shelf, northern Georges Bank, and in the Bay of Fundy. Given the breadth and importance of this task, it is necessary that a method for rapid analysis be developed that allows for the assessment of potential extinction vulnerability of fish species, and uses assessment criteria that are explicitly defined and relevant to marine species in Canada. The approach undertaken by the Maritimes Region was to develop a scoring matrix that (1) quantifies the dynamics of a species' abundance and distribution and allows for rapid determination of whether or not that species may be at risk of extinction, and (2) allows for easy comparison across taxa thrnugh standardization of scoring. The intention behind the matrix was to create a more intuitive ranking scheme than has been used in the past. The potential extinction vulnerability of each species is graded out of 100. A high score represents a relatively high risk of extinction or extirpation from Canadian waters. Species assigned high scores by this rapid process can then be subjected to further, indepth evaluation. The criteria and conditions for the matrix were derived from criteria used by COSEWIC, and DFO's General Status Pilot Project. However, a new set of conditions were developed for some criteria to address several of the deficiencies that existed in the General Status approach, and to accentuate factors that may of greater significance to extinction vulnerability than to the assessment of current abundance. This exercise was intended to test the validity and utility of a matrix approach for rapid assessment of extinction vulnerability and ease of comparison among species. The matrix is not intended to replace the formal assessment process, but to identify species that may need higher priority for a formal COSEWIC assessment. A prioritized candidate species list was created based on the results of the matrix analysis

This book was released on 2020-02-28 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Worldwide review of bottom fisheries in the high seas in 2016 is an update to the first Worldwide review of bottom fisheries in the high seas, published in 2009 based on information from 2003 to 2006. It provides states and other interested parties with a summary of the current status of high seas bottom fisheries worldwide. The present, updated review begins with a description of the demersal finfish and shellfish resources, before offering a global perspective on fisheries and management; it then provides specific, regional information over eleven chapters covering the high seas of the world’s oceans, by region. Drawing on data up to and including 2016, it provides a survey of the current state of bottom fisheries since the original Worldwide review, considering these fisheries in the context of their historical evolution.

For most fisheries there is little or no info. on the status of stocks and in many cases we do not even know what is being caught where." Illus. A print on demand report.
Download or read book Exploration of the Seas written by National Research Council and published by National Academies Press. This book was released on 2003-11-04 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the summer of 1803, Thomas Jefferson sent Meriwether Lewis and William Clark on a journey to establish an American presence in a land of unqualified natural resources and riches. Is it fitting that, on the 200th anniversary of that expedition, the United States, together with international partners, should embark on another journey of exploration in a vastly more extensive region of remarkable potential for discovery. Although the oceans cover more than 70 percent of our planet's surface, much of the ocean has been investigated in only a cursory sense, and many areas have not been investigated at all. Exploration of the Seas assesses the feasibility and potential value of implementing a major, coordinated, international program of ocean exploration and discovery. The study committee surveys national and international ocean programs and strategies for cooperation between governments, institutions, and ocean scientists and explorers, identifying strengths, weaknesses, and gaps in these activities. Based primarily on existing documents, the committee summarizes priority areas for ocean research and exploration and examines existing plans for advancing ocean exploration and knowledge.
Download or read book The Last Billion Years written by The Atlantic Geoscience Society (AGS) and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Expanded and updated edition of bestselling full-colour history of geological heritage in Nova Scotia, New Brunswick, and PEI, featuring texts from experts and thousands of illustrations, including paintings, photographs, maps, and diagrams. The rocks and fossils of the Maritime Provinces of Canada (New Brunswick, Nova Scotia, and Prince Edward Island) tell a fascinating story of the last billion years. The story unravels many surprises, for example: Halifax and southern Nova Scotia were once situated near the South Pole and attached to Africa. The positions of present-day Halifax and Saint John were once on separate continents. The red rocks of Prince Edward Island were formed in a monsoonal climate. Cliffs around the Bay of Fundy have yielded the oldest dinosaurs in Canada. As recently as 20,000 years thick ice covered the Maritimes and extended onto the continental shelf. These topics, and many more, are explored in this revised and updated edition of The Last Billion Years, a book for anyone interested in the origin and evolution of the Maritime Provinces. Beautifully and profusely illustrated in full colour, The Last Billion Years features original paintings of ancient vistas, photographs, and informative diagrams and sketches.
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 2013-04-17 with total page 421 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.
