Book Synopsis The Use of CITES for Commercially-exploited Fish Species by : Solène Guggisberg
Download or read book The Use of CITES for Commercially-exploited Fish Species written by Solène Guggisberg and published by Springer. This book was released on 2015-12-11 with total page 469 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book examines the legality, adequacy and efficacy of using the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) for commercially-exploited fish species and assesses whether the existing institutional cooperation with the Food and Agriculture Organization (FAO) and regional fisheries management organizations (RFMOs) is efficient. This case-study also provides an interesting lens to approaching wider international law issues. Indeed, finding ways to achieve effective governance of transboundary or global natural resources is central to the peaceful use of oceans and land. Furthermore, the role of science in advising decision-makers is a sensitive issue, which deserves scrutiny and is similar in many regimes. Finally, the complex problem of fragmentation of international law is acute in various fields of environmental law, as in all rapidly developing areas of international regulations.
Book Synopsis Remote Sensing of Reef Fish Communities by : Anders Jensen Knudby
Download or read book Remote Sensing of Reef Fish Communities written by Anders Jensen Knudby and published by . This book was released on 2009 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the last three decades of coral reefs studies, the large areal coverage of data derived from satellite images has increasingly been used to complement the more detailed but spatially limited data produced by conventional fieldwork. Continuous improvement in sensor capabilities, along with the development of increasingly refined methods for image processing, has lead to ever more accurate maps of physical and biological variables of importance to reef ecology. During the same period, an abundance of field studies have documented statistical relationships between aspects of the reef habitat and its fish community. Despite numerous stochastic influences, such as spatially concentrated and temporally variable fish recruitment pulses or the selective and patchy mortality caused by fishing, several aspects of habitat have been shown to significantly influence the fish community. Fortunately the most important of these, water depth, the structural complexity of the reef, and the cover of live coral, are possible to estimate from currently available satellite imagery. The research presented in the following pages has combined the statistical relationships between the fish community and its habitat with the capability of satellite imagery to map that habitat, thereby answering the research question: How can remote sensing be used to map coral reef fish communities? In the process, a set of new techniques for predictive modeling of complex relationships have been compared, the influence of a range of habitat variables on the fish community quantified, the spatial scales at which the fish-habitat relationships are strongest have been explored, and new methods for deriving estimates of some aspects of the coral reef habitat from satellite imagery have been developed. The results presented in this thesis thus contribute to the further understanding of fish-habitat relationships, while providing a template for producing spatially explicit predictive models of fish community variables. This is not only of scientific interest, but also of substantial value to the conservation community that tries to protect the world's remaining healthy coral reef ecosystems, and their fish communities, from an array of man-made influences.

Book Synopsis Defining and Mapping Essential Fish Habitat for Reef Fishes in Kosrae, Federated States of Micronesia by : Mark H. Tupper
Download or read book Defining and Mapping Essential Fish Habitat for Reef Fishes in Kosrae, Federated States of Micronesia written by Mark H. Tupper and published by . This book was released on 2006 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The objective of this project was to determine spawning and nursery habitat (as defined by Beck et al. 2001) for 3 species of commercially valuable reef fishes in Kosrae: humphead wrasse Cheilinus undulatus, blacktail snapper Lutjanus fulvus, and humpback red snapper Lutjanus gibbus. L. fulvus and L. gibbus are moderately large (maximum size 40-50 cm) snappers that are common throughout Micronesia and are important reef fisheries species. Specifically, mark -- recapture techniques were used to compare density, persistence, growth, and movement of newly settled and adult snappers and humphead wrasse in a variety of habitat types. Another objective was to create detailed habitat maps for key areas of Kosrae. In order for fisheries management to incorporate essential fish habitat, information on the location and extent of such habitat must be available to managers in a format that is intuitive and readily accessible. Digital habitat maps created in a Geographic Information System (GIS) format are particularly useful in that they allow the merging of habitat data with other thematic layers, such as fish or coral abundance and distribution, fishery catch and effort, pollution sources, etc. Such maps can be used to support a wide range of coastal management activities in addition to fisheries managemen"--Page 3.

Book Synopsis While Stocks Last by : Yvonne Sadovy
Download or read book While Stocks Last written by Yvonne Sadovy and published by Adb Pacific Studies. This book was released on 2003 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study brings together the work of many researchers to arrive at suggestions for solving the environmental problems caused by the long-running live-fish trade in Southeast Asia. With strong demand coming from mainland China, this trade has caused rampant over-fishing in Asia and consequent damage to outside subsistence or commercial fisheries. This work discusses the role of regional organizations in regulating the trade as well as ways to decrease nontarget fish mortality in an industry that often employs cyanide solution as a fishing tool.
Book Synopsis Ecological Connectivity among Tropical Coastal Ecosystems by : Ivan Nagelkerken
Download or read book Ecological Connectivity among Tropical Coastal Ecosystems written by Ivan Nagelkerken and published by Springer Science & Business Media. This book was released on 2009-09-23 with total page 617 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mangrove forests, seagrass beds, and coral reefs are circumtropical ecosystems that are highly productive, and provide many important biological functions and economic services. These ecosystems cover large surface areas in the shallow tropical coastal seascape but have suffered from serious human degradation, especially in the last few decades. Part of their diversity, productivity, and functioning seems to be based on their juxtaposition. Especially in the last decade significant advances have been made on new insights into their ecological connectivity. This authoritative book provides a first-time comprehensive review of the major ecological interactions across tropical marine ecosystems that result from the mutual exchange of nutrients, organic matter, fish, and crustaceans. A group of leading authors from around the world reviews the patterns and underlying mechanisms of important biogeochemical and biological linkages among tropical coastal ecosystems in 15 chapters. Included are chapters that review cutting-edge tools to study and quantify these linkages, the importance of such linkages for fisheries, and how tropical ecosystems should be conserved and managed for sustainable use by future generations. The book uses examples from all over the world and provides an up-to-date review of the latest published literature. This book is a ‘must read’ for professionals working on the conservation, management, and ecology of mangrove, seagrass and coral reef ecosystems.

Book Synopsis Food Webs and the Dynamics of Marine Reefs by : Tim McClanahan
Download or read book Food Webs and the Dynamics of Marine Reefs written by Tim McClanahan and published by Oxford University Press. This book was released on 2008-04-16 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biologists have made significant advances in our understanding of the Earth's shallow subtidal marine ecosystems, but the findings on these disparate regions have never before been documented and gathered in a single volume. Now, in Food Webs and the Dynamics of Marine Reefs, Tim R. McClanahan and George M. Branch fill this lacuna with a comparative and comprehensive collection of nine essays written by experts on specific aquatic regions. Each essay focuses on the food webs of a respective ecosystem and the factors affecting these communities, from the intense and direct pressure of human influence on fisheries to the multi-vector contributors to climate change. The book covers nine shallow water marine ecosystems from selected areas throughout the world: four coral reef systems, three hard bottom systems, and two kelp systems. In summarizing their organization, human influence on them, and recent developments in these ecosystems, the authors contribute to our understanding of their ecological organization and management. Food Webs and the Dynamics of Marine Reefs will be a useful tool for all benthic marine investigators, providing an expert, comparative view of these aquatic regions.
Book Synopsis Endangered Forested Wetlands of Sundaland by : Gianluca Polgar
Download or read book Endangered Forested Wetlands of Sundaland written by Gianluca Polgar and published by Springer. This book was released on 2017-08-31 with total page 163 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book informs readers on the ecology, ecosystem services, and management of Sundaland wetland ecosystems, discussing the concepts and tools necessary to conserve these imperiled habitats. Sundaland is a biogeographically defined area of South East Asia characterised by an exceptional concentration of endemic species. The unprecedented loss of wetland habitats within Sundaland warrants urgency in implementing conservation actions. The authors are both researchers who have witnessed the ongoing losses of wetland habitats in Sundaland. The first chapter introduces fundamental concepts of ecosystems, ecological processes and ecosystem services of coastal and inland wetlands. The second chapter provides an overview of the global and regional conservation status of these ecosystems. The third chapter advances the importance of wetlands management at the landscape level (drainage basins), and proposes to adopt the concept of Ecotonal Networks (ENTs) as a sustainable management method, within the theoretical framework of Resilience Theory. The fourth chapter showcases potential flagship species that can aid in raising awareness on these endangered but poorly-known ecosystems. The fifth chapter discusses sustainable ecotourism as a viable and profitable industry to manage non-urban wetland areas of Sundaland, while providing specific suggestions for future developments. The book is written for ecosystem managers, conservation scientists, ecologists, and nature enthusiasts. It consists of a coherently arranged set of scientifically accurate tools that consider societal, cultural, and economic factors to succeed in the conservation of the Sundaland wetlands, as well as other wetland habitats in the world.

Book Synopsis Biology of Parrotfishes by : Andrew S. Hoey
Download or read book Biology of Parrotfishes written by Andrew S. Hoey and published by CRC Press. This book was released on 2018-03-05 with total page 556 pages. Available in PDF, EPUB and Kindle. Book excerpt: Parrotfish are found on almost every coral reef in the world. This ubiquity and uniqueness of their feeding action make them one of the most important groups of fishes within coral reef ecosystems. But why, exactly, are parrotfish so important to reefs? Can the evolution of a particular jaw morphology and feeding action really have had such a large impact on the health and functioning of the world's coral reefs? This book introduces the reader to this fascinating group of fishes (Labridae, Scarinae), from the morphological innovation of a jaw that has the power to bite through solid calcium carbonate, to the threats currently faced by parrotfish populations around the world. It contains new insights into their diet and food processing ability, and lifehistories, and concludes with an overview of emerging and future research directions.
