Book Description
The increase in commercial fisheries production over the last 50 years has been accompanied by an increase in the level of incidental catch and discarding of a number of species. Approximately one quarter of the marine commercial catch destined for human consumption is discarded at sea. This has raised the concern of a number of groups in society, including environmentalists, humanitarians and fishers themselves. In this paper, the economic incentives to discard fish are examined. The effects of different managemenet policies on these incentives are also investigated. The concept of an optimal level of discarding is discussed taking into account the externalities that can be created by discarding. Finally, the effectiveness of various measures to reduce the level of discarding is reviewed. these including technical, administrative and economic measures.

Book Description
Under the Magnuson-Stevens Fisheries Conservation and Management Act (FCMA), managers are required to use the "best scientific information available" in the preparation of federal fishery management plans (National Standard 2 in the FCMA). However, the Act provides no further guidance as to how conformance to this standard should be determined. Because adherence to this standard has often been contentious, Congress has considered adding a definition for what constitutes "best scientific information available" in the reauthorization of the FCMA. This report examines both the current application and the controversy over the standard and concludes that a legislative definition would be too inflexible to accommodate regional differences and future advances in science and technology. Instead, the report recommends that NOAA Fisheries adopt procedural guidelines to ensure that the scientific information used in the development of fishery management plans is relevant and timely and is the product of processes characterized by inclusiveness, transparency and openness, timeliness, and peer review.

Book Description
This collection addresses the central question of how the current international framework for the regulation of fisheries may be strengthened in order to meet the challenges posed by changing fisheries and ocean conditions, in particular climate change. International fisheries law has developed significantly since the 1990s, through the adoption and establishment of international instruments and bodies at the global and regional levels. Global fish stocks nevertheless remain in a troubling state, and fisheries management authorities face a wide array of internal and external challenges, including operational constraints, providing effective management advice in the face of scientific uncertainty and non-compliance by States with their international obligations. This book examines these challenges and identifies options and pathways to strengthen international fisheries law. While it has a primarily legal focus, it also features significant contributions from specialists drawn from other disciplines, notably fisheries science, economics, policy and international relations, in order to provide a fuller context to the legal, policy and management issues raised. Rigorous and comprehensive in scope, this will be essential reading for lawyers and non-lawyers interested in international fisheries regulation in the context of profoundly changing ocean conditions.

Book Description
Twenty-five extended abstracts on bycatch management are included in this book, the proceedings of a 1996 American Fisheries Society symposium. The AFS meeting was convened because of increasing concern about bycatch of fishes, crustaceans, mammals, and turtles in commercial and recreational fisheries.

Book Description
The project “Sustainable management of bycatch in Latin America and Caribbean trawl fisheries” was financed by GEF, implemented and executed by FAO. With an overall evaluation rating of Highly Satisfactory, the assessment has identified notable results in strengthening regional collaboration, improving legal frameworks and co-management mechanisms; successful trials of bycatch reduction devices; and building capacity, including of women. The global environment objective (GEO) and the project development objective (PDO) were partially achieved, reflecting the over-ambitiousness of the design. However, the enabling environment created, and the transformational results will contribute towards achievement of these objectives in the long-term. Strategic partnerships and the high level of stakeholder engagement including the private sector contributed to successful delivery. Recommendations include actions to be taken by the project partners and stakeholders to build on the project results to achieve sustainable, long-term impact; thematic areas for follow-up projects; more realistic project objectives and improvement in institutional arrangements and administrative procedures for future projects; sustaining partnerships; enhancing livelihoods and empowerment of women fish workers; and better communication and knowledge management.

Book Description
Congress has promoted fisheries science for over a century and its involvement in fisheries management took a great leap forward with passage of the Fisheries Conservation and Management Act of 1976. In the past decade, Congress has requested advice from the National Research Council (NRC) on both national issues (e.g., individual fishing quotas and community development quotas) and the assessments related to specific fisheries (Northeast groundfish). This report was produced, in part, in response to another congressional request, this time related to the assessments of the summer flounder stocks along the East Coast of the United States. Following the initial request, the NRC, National Marine Fisheries Service (NMFS), and congressional staff agreed to broaden the study into a more comprehensive review of marine fisheries data collection, management, and use.
