Reef fish spawning aggregations, ranging from small groups to many tens of thousands of individuals, are spectacular but poorly known natural phenomena whereby fish assemble at specific times and locations to spawn. For some species these large groups may be the only form of reproduction, the high fish numbers briefly giving a false impression of stability and abundance—an ‘illusion of plenty’. They are often a focus for intensive seasonal fishing because of their predictability and because many important commercial fishes form them. Highly vulnerable to overexploitation, many aggregations and their associated fisheries, have disappeared or are in decline. Few are effectively managed or incorporated into protected areas. Aggregations are not well understood by fishery scientists, managers and conservationists and their significance little appreciated by fishers or the wider public. To ensure their persistence to replenish important fisheries in coral ecosystems, maintain their ecosystem function and continue to delight divers, a significant change in perspective is needed to foster protection and management. This book provides comprehensive and practical coverage of the biology, study and management of reef fish aggregations, exploring their how, when, where, and why. It explores ways to better protect, study, manage and conserve them, while identifying key data gaps and questions. The text is extensively illustrated with many unique, never before published, photographs and graphics. Case studies on over 20 interesting and important fishes are included, outlining their biology and fisheries and highlighting major concerns and challenges.
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.
Fish and fish products are amongst the most highly traded food items in the world today, with most of the world’s countries reporting some fish trade. This assessment of commercial trade in CITES-listed marine species occurs within a broader context of globalization and a more general rapid expansion of the international trade in fish and fish products. It summarizes ten years (2007–2016) of trade in a subset of commercially exploited marine taxa listed in CITES Appendix II. We examine both CITES trade data reporting processes (including information on the practical elements of reporting by CITES Parties) and analyse CITES trade records. The analysis shows how, for Appendix II CITES-listed marine species, the overall number of direct export transactions reported by CITES Parties has increased sevenfold during 1990–2016 and how trade for each CITES-listed marine species sub-group has changed through time. An assessment is made, with assistance from species and trade experts, on the strengths and challenges of collating and reporting on trade in CITES-listed marine species. Additional datasets of relevance to marine species trade are highlighted, and recommendations for further refining and improving CITES trade reporting for marine species are provided.
Coral Reef Fishes is the successor of The Ecology of Fishes on Coral Reefs. This new edition includes provocative reviews covering the major areas of reef fish ecology. Concerns about the future health of coral reefs, and recognition that reefs and their fishes are economically important components of the coastal oceans of many tropical nations, have led to enormous growth in research directed at reef fishes. This book is much more than a simple revision of the earlier volume; it is a companion that supports and extends the earlier work. The included syntheses provides readers with the current highlights in this exciting science. * An up-to-date review of key research areas in reef fish ecology, with a bibliography including hundreds of citations, most from the last decade * Authoritative and provocative chapters written to suggest future research priorities * Includes discussions of regulation of fish populations, dispersal or site fidelity of larval reef fishes, sensory and motor capabilities of reef fish larvae, and complexities of management of reef species and communities
In recent years, an increasing number of commercially exploited and managed aquatic species, including sharks and rays, have been listed in the Appendices to the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). The listing of some species in CITES Appendix II has necessitated attention from the fisheries sector of States on how listing would impact on the management of the relevant fisheries. This sourcebook and the research process involved in its development highlighted the opportunity to implement CITES through national fisheries legal frameworks. Indeed, in certain cases, doing so can prove to be vital in giving practical effect to CITES while simultaneously enhancing fisheries management regimes and ensuring that all activities along the fisheries value chain, especially the international trade in CITES-listed aquatic species, are legal, traceable and sustainable. The study recognizes that communities operating within the CITES regime and in the fisheries sectors have their own particular areas of work. However, they should cooperate and coordinate their work where they share the common high-level objectives of ensuring responsible, legal and sustainable utilization of resources, including species, biodiversity and ecosystems, and implementing the relevant Sustainable Development Goals. This sourcebook was first published in 2020, designated as a "super year" for nature and biodiversity. The second edition of this sourcebook was developed to take into account and reflect the outcomes of the 19th meeting of the Conference of the Parties to CITES, in 2022. The sourcebook is a timely and useful contribution to fisheries management as it seeks to provide support in: (i) raising awareness of CITES; (ii) enhancing comprehension of the CITES regime and its relationship with the fisheries sector; and (iii) where a deliberate decision is made by a country to implement CITES through its national fisheries legal frameworks, providing guidance on what to do and how to do it.
An increasing number of commercially exploited and managed aquatic species has been listed in the Appendices to the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), triggering the attention from the fisheries sector of States on how listing would impact on the management of the relevant fisheries. CITES regulates international trade in certain aquatic species, including those which are, and can be, commercially exploited and which are being managed by the fisheries sector. The fisheries sector legal frameworks will have to recognize and enable the various requirements provided for in CITES, including the making of non-detriment findings and ensuring that there is a designated management authority and scientific authority to take certain decisions in respect of listed commercially exploited and managed aquatic species. This sourcebook provides clarifications on the relationship of CITES with the fisheries sector and provides guidance on how national fisheries legal frameworks can optimize the implementation of CITES. The realisation of this sourcebook in 2020, designated as a “super year” for nature and biodiversity, represents a timely and useful contribution to fisheries management, by (i) raising awareness of CITES; (ii) enhancing comprehension of the CITES regime and its relationship with the fisheries sector and (iii) where a deliberate decision is made by a country to implement CITES through its national fisheries legal frameworks, providing guidance as to what do it and how to do it.
This excellent second edition of Fisheries Biology, Assessment and Management, has been fully updated and expanded, providing a book which is an essential purchase for students and scientists studying, working or researching in fisheries and aquatic sciences. In the same way that excessive hunting on land has threatened terrestrial species, excessive fishing in the sea has reduced stocks of marine species to dangerously low levels. In addition, the ecosystems that support coastal marine species are threatened by habitat destruction, development and pollution. Open access policies and subsidised fishing are placing seafood in danger of becoming a scarce and very expensive commodity for which there is an insatiable demand. Positive trends include actions being taken to decrease the incidental catches of non-target species, consumer preferences for seafood from sustainable fisheries, and the establishment of no-take areas that provide refuges for marine species. But there is an urgent need to do more. Because there is an increasing recognition of the need to manage ecosystems as well as fish stocks, this second edition of this bestselling text book includes an additional chapter on marine ecology. Chapters on parameter estimation and stock assessment now include step-by-step instructions on building computer spreadsheet models, including simulations with random variations that realistically emulate the vagaries of nature. Sections on ecosystem management, co-management, community-based management and marine protected areas have been expanded to match the increased interest in these areas. Containing many worked examples, computer programs and numerous high quality illustrations, Fisheries Biology, Assessment and Management, second edition, is a comprehensive and essential text for students worldwide studying fisheries, fish biology, aquatic and biological sciences. As well as serving as a core text for students, the book is a superb reference for fisheries and aquatic researchers, scientists and managers across the globe, in both temperate and tropical regions. Libraries in all universities where fish biology, fisheries, aquatic sciences and biological sciences are studied and taught will need copies of this most useful new edition on their shelves.

During the last decade, there has been a shift in the governance and management of fisheries to a broaderapproach that recognizes the participation of fishers, local stewardship, and shared decision-making.Through this process, fishers are empowered to become active members of the management team,balancing rights and responsibilities, and working in partnership with government. This approach iscalled co-management.This handbook describes the process of community-based co-management from its beginning, throughimplementation, to turnover to the community. It provides ideas, methods, techniques, activities, checklists,examples, questions and indicators for the planning and implementing of a process of community-basedco-management. It focuses on small-scale fisheries (freshwater, floodplain, estuarine, or marine) indeveloping countries, but is also relevant to small-scale fisheries in developed countries and to themanagement of other coastal resources (such as coral reefs, mangroves, sea grass, and wetlands). Thishandbook will be of significant interest to resource managers, practitioners, academics and students ofsmall-scale fisheries.
