生态系统相关文件Models for an ecosystem approach to fisheries. This report reviews the methods available for assessing the impacts of interactions between species and fisheries and their implications for marine fisheries management. A brief description of the various modelling approaches currently in existence is provided, highlighting in particular features of these models which have general relevance to the field of the ecosystem approach to fisheries (EAF). The report concentrates on the currently available models representative of general types such as bionergetic models, predator-prey models and minimally realistic models. Short descriptions are given of model parameters, assumptions and data requirements. Some of the advantages, disadvantages and limitations of each of the approaches in addressing questions pertaining to EAF are discussed. The report concludes with some recommendations for moving forward in the development of multi-species and ecosystem models and for the prudent use of the currently available models as tools for ...Building an ecosystem approach to aquaculture. FAO/Universitat de les Illes Balears Expert Workshop. 7–11 May 2007, Palma de Mallorca, Spain. Aquaculture growth worldwide involves the expansion of cultivated areas, a higher density of aquaculture installations and farmed individuals, and greater use of feed resources produced outside the immediate culture area. To ensure that such development of the sector does not carry negative impacts on the environment and on parts of society due to weak regulation or poor management, an ecosystem approach for aquaculture (EAA) is encouraged. “An ecosystem approach for aquaculture is a strategy for the integration of the activity within the wider ecosystem in such a way that it promotes sustainable development, equity, and resilience of interlinked social and ecological systems”. This strategy should be guided by three main principles that should ensure the contribution of aquaculture to sustainable development: i) aquaculture should be developed in the context of ecosystem functions and services with no degradation of these beyond their resilience capacity; ii) aquaculture should ...Putting into practice the ecosystem approach to fisheries. Although the principles of an ecosystem approach to fisheries (EAF) are not new, there is very little practical experience in their implementation. Translating high-level policy goals on EAF into operational objectives and actions is now the key challenge to sustainable fisheries. This booklet will provide an overview of EAF, for marine capture fisheries, and its benefits; consider what is required to implement EAF; consider the range of management measures available; provide an overview of the management process; outline any outstanding research requirements; and list the main threats to the implementation of EAF. Book Ecosystems Fisheries Marine fisheries Fishery management Fisheries and aquaculture - General aspectsThe ecosystem approach to fisheries. Issues, terminology, principles, institutional foundations, implementation and outlook. Ecosystems are complex and dynamic natural units that produce goods and services beyond those of benefit to fisheries. Because fisheries have a direct impact on the ecosystem, which is also impacted by other human activities, they need to be managed in an ecosystem context. The meaning of the terms "ecosystem management", "ecosystem-based management", "ecosystem approach to fisheries" (EAF), etc., are still not universally defined and progressively evolving. The justification of EAF is evident in the characteristics of an exploited ecosystem and the impacts resulting from fisheries and other activities. The rich set of international agreements of relevance to EAF contains a large number of principles and conceptual objectives. Both provide a fundamental guidance and a significant challenge for the implementation of EAF. The available international instruments also provide the institutional foundations for EAF. The FAO Code of Conduct for Responsible Fisheries is particularly ...Fisheries management. 2. The ecosystem approach to fisheries These guidelines have been produced to supplement the FAO Code of Conduct for Responsible Fisheries. The Code and many international agreements and conferences highlight the many benefits that can be achieved by adopting an ecosystem approach to fisheries (EAF) and elaborate a number of agreed principles and concepts relating to EAF. documents and articles Fishery management Fisheries development Ecosystems Fisheries and aquaculture - General aspectsHuman dimensions of the ecosystem approach to fisheries: an overview of context, concepts, tools and methods This document aims to provide a better understanding of the role of the economic, institutional and sociocultural components within the ecosystem approach to fisheries (EAF) process and to examine some potential methods and approaches that may facilitate the adoption of EAF management. It explores both the human context for the ecosystem approach to fisheries and the human dimensions involved in implementing the EAF. For the former, the report provides background material that is essential to understand prior to embarking on EAF initiatives, including an understanding of key concepts and issues, of the valuation of aquatic ecosystems socially, culturally and economically, and of the many policy, legal, institutional, social and economic considerations relevant to the EAF. With respect to facilitating EAF implementation, the report deals with a series of specific aspects: (1) determining the boundaries, scale and scope of the EAF; (2) assessing the various benefits and costs ...Ecosystem-Based Management of Fisheries; Opportunities and Challenges for Coordination between Marine Regional Fishery Bodies and Regional Seas Conventions Meeting Fishery policies Fishery management Government International cooperation Law of the sea Fishing rights Marine ecology Ecosystems Public administration Development economics and policies Fisheries and aquaculture - General aspectsThe Rome Declaration on the Implementation of the Code of Conduct for Responsible Fisheries. Adopted by the FAO Ministerial Meeting on Fisheries. Rome, Italy, 10-11 March 1999 At the invitation of the Director-General of FAO, the Ministers responsible for fisheries met in Rome on 10 and 11 March 1999 as a sign of their attachment to the implementation of the Code of Conduct for Responsible Fisheries adopted by the FAO Conference at its Twenty-eighth Session in October 1995. In this regard, the Ministerial Meeting was especially appreciative of FAO¿s role in promoting the application of the Code of Conduct for Responsible Fisheries and the increasingly wide adoption of the Code by States and concerned organizations.
