  • SUSTAINABLE FISHERIES and RESPONSIBLE AQUACULTURE: a Guide for USAID Staff and Partners
    SUSTAINABLE FISHERIES AND RESPONSIBLE AQUACULTURE: A Guide for USAID Staff and Partners June 2013 ABOUT THIS GUIDE GOAL This guide provides basic information on how to design programs to reform capture fisheries (also referred to as “wild” fisheries) and aquaculture sectors to ensure sound and effective development, environmental sustainability, economic profitability, and social responsibility. To achieve these objectives, this document focuses on ways to reduce the threats to biodiversity and ecosystem productivity through improved governance and more integrated planning and management practices. In the face of food insecurity, global climate change, and increasing population pressures, it is imperative that development programs help to maintain ecosystem resilience and the multiple goods and services that ecosystems provide. Conserving biodiversity and ecosystem functions are central to maintaining ecosystem integrity, health, and productivity. The intent of the guide is not to suggest that fisheries and aquaculture are interchangeable: these sectors are unique although linked. The world cannot afford to neglect global fisheries and expect aquaculture to fill that void. Global food security will not be achievable without reversing the decline of fisheries, restoring fisheries productivity, and moving towards more environmentally friendly and responsible aquaculture. There is a need for reform in both fisheries and aquaculture to reduce their environmental and social impacts. USAID’s experience has shown that well-designed programs can reform capture fisheries management, reducing threats to biodiversity while leading to increased productivity, incomes, and livelihoods. Agency programs have focused on an ecosystem-based approach to management in conjunction with improved governance, secure tenure and access to resources, and the application of modern management practices.

Evidence is presented that the Mainstreaming global fishery community incrementally adopted sustainable development principles from both before and after Sustainable development the 1992 adoption of the Convention on Biological Diversity, integrating a broader set of ecosystems goals into Fisheries fisheries. Actions taken by the Food and Agriculture Organization of the United Nations (FAO) and regional and Conservation national fishery agencies to fulfil their mandate are discussed, in addition to objectives for more sustainable Cooperation fisheries that have led to significant expansions in legal frameworks, policies and practices in terms of biodi- versity conservation. The paper also highlights the growing importance of cross-sectoral cooperation in the resolution of historical disagreements between fisheries and environmental interests, in spite of the various sectoral interests. In this evolution, despite many target stocks not yet being sustainably managed, fisheries approaches are progressively focusing on a broader range of biodiversity considerations, whereas conservation interests are increasingly adopting more socially inclusive approaches.

  • Overcoming Overexploitation of Fisheries: Creating a More Sustainable Fishing Industry Along the Gulf of Mexico Coast
    OVERCOMING OVEREXPLOITATION OF FISHERIES: CREATING A MORE SUSTAINABLE FISHING INDUSTRY ALONG THE GULF OF MEXICO COAST By Gwendolyn Ricco University of Colorado at Boulder A thesis submitted to the University of Colorado at Boulder in partial fulfillment Of the requirements to receive Honors designation in Environmental Studies May 2013 Thesis Advisors: Nancy Billica, Political Science, Committee Chair Dale Miller, Environmental Studies Sam Fitch, Political Science © 2013 by Gwendolyn Ricco Abstract With increasing global population coupled with high levels of consumption, natural resource scarcity is a vital issue in the management and restructuring of commercial industries. Resource conservation is a widely studied field to determine the current and past trends of resource availability. As oceans comprise 70 percent of our planet’s surface, the study of marine ecosystems and human impacts due to fishing enterprises is becoming increasingly important, especially as fishing stocks across the world are in danger of collapse. This study focuses on the role of fishery management policies and practices in the United States and in particular, how these policies can be changed to establish industries that promote long-term sustainability. Specifically, a policy recommendation for the Gulf of Mexico fishery system is advanced, drawing from the lessons learned through examination of Alaskan and New England fisheries. This Gulf of Mexico case study is designed to produce a dialogue considering the sustainability of our fishing industries in the United States by considering biological, political, and economic factors of each region in order to create a more local and contextualized policy recommendation for the Gulf of Mexico to transition effectively and efficiently towards a more sustainable future.

  • Adaptive Fisheries Management for Nearshore Fisheries Jono Wilson, Gavin Mcdonald, Rod Fujita, Kendra Karr
    Adaptive Fisheries Management for Nearshore Fisheries Jono Wilson, Gavin McDonald, Rod Fujita, Kendra Karr “If you don’t know where you’re going, you’ll end up someplace else” -Yogi Berra Introduction Effective management of marine capture fisheries promotes social and economic returns to fishery stakeholders while maintaining a portfolio of ecosystem benefits that society values. For some fisheries, management actions are determined using quantitative stock assessments to estimate the status of the resource relative to predefined targets or “reference points,” such as the biomass that achieves maximum sustainable yield (Walters and Martell 2002). However, more than 80% of global fisheries catch occurs in fisheries that lack the necessary data, resources, infrastructure, and expertise to use conventional stock assessment models to set sustainable management actions (Costello et al 2012). Instead, these fisheries often go unmanaged, or are managed with little scientific input, resulting in suboptimal harvest rates, ineffective regulations, and poor social and economic welfare for communities dependent on fishing. Management decisions in data- and resource-limited situations regarding how to appropriately adjust fishing pressure, and by how much, can be the most difficult assignment managers must undertake. Too often, fisheries are not managed at all or management measures are based on standard practices without an adequate scientific basis; this creates a high risk of overfishing and the loss of economic and social benefits from fisheries. Here we describe a way to make fishery management decisions based on science, even when data and capacity are limited. Designing this adaptive management framework starts by defining goals for key target species or ecosystem values using the input of both managers and stakeholders (e.g., fisherman, non-profits, etc.).

  • The Legal Context of United States Fisheries Management and the Evolution of Rights-Based Management in Alaska
    369 The legal context of United States fisheries management and the evolution of rights-based management in Alaska K.R. Criddle School of Fisheries and Ocean Sciences University of Alaska Fairbanks 11120 Glacier Highway, Juneau, AK, United States of America 99801 [email protected] 1. LEGAL CONTEXT OF UNITED States FISHERIES MANAGEMENT 1.1 Overview Fisheries in the United States are governed under a composite of overlapping federal, multi-state, state, and tribal authorities and are conditioned by treaties and compacts. In general, individual states have jurisdiction over fisheries in lakes, streams, and rivers within state boundaries, and in marine waters within three miles of their coast. For Texas and the Gulf of Mexico coast (i.e. the west coast) of Florida, state jurisdiction extends to nine miles. Before 1976, federal jurisdiction included fisheries in lakes, streams and rivers within federal lands and in waters from three to twelve miles (or nine in Texas and Florida) offshore. That authority was extended to 200 miles pursuant to the Magnuson Fisheries Conservation and Management Act of 1976 (renamed the Magnuson-Stevens Fisheries Conservation and Management Act, MSFCMA, in the 1996 reauthorisation). Multi-state compacts, such as the Atlantic States Marine Fisheries Commission, the Gulf States Marine Fisheries Commission and the Pacific States Marine Fisheries Commission, coordinate state management of shared stocks of migratory species. Subsistence, sport, and commercial fisheries in lakes, streams, and rivers that flow through or abut certain tribal lands are governed under treaties negotiated with indigenous peoples. In addition, the management of some fisheries operates within bounds established under international treaties.

  • Bridging the Divide Between Fisheries and Marine Conservation Science
    BULLETIN OF MARINE SCIENCE. 87(2):251–274. 2011 doi:10.5343/bms.2010.1089 BRIDGING THE DIVIDE BETWEEN FISHERIES AND MARINE CONSERVATION ScIENCE Anne K Salomon, Sarah K Gaichas, Olaf P Jensen, Vera N Agostini, NA Sloan, Jake Rice, Tim R McClanahan, Mary H Ruckelshaus, Phil S Levin, Nicholas K Dulvy, and Elizabeth A Babcock ABSTRACT Researchers from traditionally disparate disciplines and practitioners with typically incongruent mandates have begun working together to better understand and solve marine conservation and sustainable yield problems. Conservation practitioners are recognizing the need to achieve conservation goals in seascapes that are a source of livelihood and food security, while fisheries management is realizing that achieving economically and ecologically sustainable fisheries requires an understanding of the role of biodiversity and ecosystem dynamics in fishery production. Yet, tensions still exist due to the unique histories, epistemologies, cultures, values, and quantitative techniques of fisheries and marine conservation science, and the often-divergent objectives of the institutions and organizations these academic disciplines inform. While there is general agreement on what needs to be achieved (less overfishing, recovery of depleted fish stocks, reduction in bycatch and habitat impacts, jobs, food production), specific objectives and how best to achieve them remain contentious and unresolved. By analyzing three contemporary yet controversial marine policies (ecosystem-based fishery management, marine protected areas, and catch shares) and specific case studies, we demonstrate how both fisheries and marine conservation science can be used to provide clear scientific advice to practitioners and provide empirical evidence of the benefits of bridging the disciplinary divide. Finally, we discuss future prospects for collaboration in an emerging issue at the nexus of conservation and fishery management: eco-certification.
