Download or read book Rebuilding of Marine Fisheries Global review written by Serge Garcia and published by . This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Rebuilding depleted stocks is a central part of the fisheries governance agenda. By analysing the available literature, Part 1 of "Rebuilding of marine fisheries" provides a global review of the emergence of the rebuilding paradigm, its key concepts, the trends in fishery resources, and the empirical evidence available on stocks depletion, collapse and rebuilding. It addresses the bio-ecological, economic, and human dimensions of rebuilding or restoration of stocks, multispecies assemblages and habitats/ecosystems and touches on the need for rebuilding at the whole sector level when depletion has become widespread and chronic. The human imensions of stocks and fisheries are given particular attention, looking at conflicting objectives, the bio-economy of rebuilding, its costs and benefits, and the distributional effects of the related reform among actors with their potential social consequences in the short and long terms. Governance is addressed in detail: legal and policy frameworks; rationale and objectives of a rebuilding regime; alternative rebuilding strategies; reference values and protocols; regulatory time-frames; risk management and harvest control rules; impacts of climatic oscillations; management tool-box; implementation guidance and performance evaluation. The document ends with a review of the determinants of success of a rebuilding programme."--Publisher's description for part 1.

Available in PDF, EPUB and Kindle. Book excerpt: Recent decades have witnessed strong declines in fish stocks aroundthe globe, amid growing concerns about the impact of fisheries onmarine and freshwater biodiversity. Fisheries biologists andmanagers are therefore increasingly asking about aspects ofecology, behaviour, evolution and biodiversity that weretraditionally studied by people working in very separate fields.This has highlighted the need to work more closely together, inorder to help ensure future success both in management andconservation. The Handbook of Fish Biology and Fisheries has beenwritten by an international team of scientists and practitioners,to provide an overview of the biology of freshwater and marine fishspecies together with the science that supports fisheriesmanagement and conservation. This volume, subtitled Fish Biology, reviews a broadvariety of topics from evolutionary relationships and globalbiogeography to physiology, recruitment, life histories, genetics,foraging behaviour, reproductive behaviour and community ecology.The second volume, subtitled Fisheries, uses much of thisinformation in a wide-ranging review of fisheries biology,including methods of capture, marketing, economics, stockassessment, forecasting, ecosystem impacts and conservation. Together, these books present the state of the art in ourunderstanding of fish biology and fisheries and will serve asvaluable references for undergraduates and graduates looking for acomprehensive source on a wide variety of topics in fisheriesscience. They will also be useful to researchers who needup-to-date reviews of topics that impinge on their fields, anddecision makers who need to appreciate the scientific backgroundfor management and conservation of aquatic ecosystems.

Marine Resources Service and published by Food & Agriculture Org.. This book was released on 1994 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document provides a review, commentary and tabulations of the main trends that have occurred in exploitation of fisheries resources since the 1970s, largely as they are reflected in the FAO database on fishery landings, supplemented with selected information from the fishery literature. Reviews were prepared separately for the 15 main areas into which FAO divides the world's oceans for statistical purposes. They are then compared from a global perspective to reveal relative trends by species and areas, which are highlighted. Several special topics are reviewed, including tuna and tuna-like species, whales and dolphins, and environmental issues in fisheries.
Download or read book Routledge Handbook of Sustainable and Regenerative Food Systems written by Jessica Duncan and published by Routledge. This book was released on 2020-08-13 with total page 481 pages. Available in PDF, EPUB and Kindle. Book excerpt: This handbook includes contributions from established and emerging scholars from around the world and draws on multiple approaches and subjects to explore the socio-economic, cultural, ecological, institutional, legal, and policy aspects of regenerative food practices. The future of food is uncertain. We are facing an overwhelming number of interconnected and complex challenges related to the ways we grow, distribute, access, eat, and dispose of food. Yet, there are stories of hope and opportunities for radical change towards food systems that enhance the ability of living things to co-evolve. Given this, activities and imaginaries looking to improve, rather than just sustain, communities and ecosystems are needed, as are fresh perspectives and new terminology. The Routledge Handbook of Sustainable and Regenerative Food Systems addresses this need. The chapters cover diverse practices, geographies, scales, and entry-points. They focus not only on the core requirements to deliver sustainable agriculture and food supply, but go beyond this to think about how these can also actively participate with social-ecological systems. The book is presented in an accessible way, with reflection questions meant to spark discussion and debate on how to transition to safe, just, and healthy food systems. Taken together, the chapters in this handbook highlight the consequences of current food practices and showcase the multiple ways that people are doing food differently. The Routledge Handbook of Sustainable and Regenerative Food Systems is essential reading for students and scholars interested in food systems, governance and practices, agroecology, rural sociology, and socio-environmental studies.
