Download or read book Global review of orange roughy (Hoplostethus atlanticus), their fisheries, biology and management written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. 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.

Download or read book Submarine Cables and the Oceans written by L. Carter and published by UNEP/Earthprint. This book was released on 2009 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are many things and services in our everyday life that we take for granted, and telecommunications is one of them. We surf the internet, send emails to friends and colleagues abroad, talk to family members in foreign countries over the phone, book airline seats and make banking transactions without actually realizing and appreciating the sophisticated technology that enables us to do so. This report covers the history and nature of cables, their special status in international law, their interaction with the environment and other ocean users and, finally, the challenges of the future. It is an evidence-based synopsis that aims to improve the quality and availability of information to enhance understanding and cooperation between all stakeholders. UNEP-WCMC in collaboration with the International Cable Protection Committee and UNEP has prepared this new report to provide an objective, factual description of the sub-marine cable industry and the interaction of submarine telecommunications (which route 95% of all international communications traffic) with the marine environment. This important report seeks to focus and guide deliberations and decision making on the wise conservation and protection of the oceans in concert with their sustainable management and use.

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.

Download or read book Seamounts written by Tony J. Pitcher and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 552 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seamounts are ubiquitous undersea mountains rising from the ocean seafloor that do not reach the surface. There are likely many hundreds of thousands of seamounts, they are usually formed from volcanoes in the deep sea and are defined by oceanographers as independent features that rise to at least 0.5 km above the seafloor, although smaller features may have the same origin. This book follows a logical progression from geological and physical processes, ecology, biology and biogeography, to exploitation, management and conservation concerns. In 21 Chapters written by 57 of the world’s leading seamount experts, the book reviews all aspects of their geology, ecology, biology, exploitation, conservation and management. In Section I of this book, several detection and estimation techniques for tallying seamounts are reviewed, along with a history of seamount research. This book represents a unique and fresh synthesis of knowledge of seamounts and their biota and is an essential reference work on the topic. It is an essential purchase for all fisheries scientists and managers, fish biologists, marine biologists and ecologists, environmental scientists, conservation biologists and oceanographers. It will also be of interest to members of fish and wildlife agencies and government departments covering conservation and management. Supplementary material is available at: www.seamountsbook.info

Download or read book Life After Logging written by E. Meijaard and published by CIFOR. This book was released on 2005-01-01 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a technical review of ecological and life history information on a range of Bornean wildlife species, aimed at identifying what makes these species sensitive to timber harvesting practices and associated impacts. It addresses three audiences: 1) those involved in assessing and regulating timber harvesting activities in Southeast Asia, 2) those involved in trying to achieve conservation goals in the region, and 3) those undertaking research to improve multipurpose forest management. This book shows that forest management can be improved in many simple ways to allow timber extraction and wildlife conservation to be more compatible than under current practices. The recommendations can also be valuable to the many governmental and non-governmental organisations promoting sustainable forest management and eco-labelling. Finally, it identifies a number of shortcomings and gaps in knowledge, which the hope can interest the scientific community and promote further research. This review is, an important scientific step toward understanding and improving sustainable forestry practices for long-term biodiversity conservation. Even in the short term, however, significant improvements can be made to improve both conservation and the efficiency of forest management, and there is no need to delay action due to a perceived lack of information. In the longer term it is expected that the recommendations from this review will be implemented, and that further research will continue to help foster an acceptable balance among the choices needed to maintain healthy wildlife populations and biodiversity in a productive forest estate.
