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. Such programs contribute to broader development goals, including food security, adaptation to climate change, biodiversity conservation, improved governance and rule of law, poverty reduction, population and family planning, and sound economic growth. USAID’s work in these fields has also shown that well-designed programs can reform the aquaculture sector, reducing threats to biodiversity and the environment while contributing to sound economic growth, food security, increased trade, livelihoods, and foreign trade. The guide addresses the following questions: • Why is it essential for reform to focus on maintaining ecosystem resilience and biodiversity, especially in light of global climate change and other global stressors? • Why is it essential for reform to focus on sustainability and responsibility? • What should a USAID manager know to design, implement, manage, and evaluate capture fisheries and aquaculture programs? • How does one design activities to ensure that sustainable development goals are addressed using environmentally responsible practices? • What are the recognized best practices for sustainable fisheries and responsible aquaculture?

SUSTAINABLE FISHERIES AND RESPONSIBLE AQUACULTURE: A Guide for USAID Staff and Partners June 2013 DISCLAIMER The authors’ views expressed in this publication do not necessarily reflect the views of the United States Agency for International Development or the United States Government. This guide is made possible by the generous support of the American people through the United States Agency for International Development (USAID). It was funded through Cooperative Agreement No. EPP-A-00-04-00014-00 to the University of Rhode Island. AUDIENCES This guide is intended primarily for USAID staff and implementing partners, but should also be useful to a broader audience, including multiple stakeholders within and across sectors. CONTENT This guide addresses capture fisheries and aquaculture in separate sections, except for the discussion of post-harvest issues where many of the topics are common to both sectors. In practice, capture fisheries and aquaculture are usually dealt with as separate sectors. However, greater attention needs to be paid to the real and potential interactions between the two sectors, especially negative impacts of aquaculture on the productivity of capture fisheries. Greater attention must also be given to the growing demand for water, the loss of biodiversity, and the encroachment and ecological degradation from coastal and inland development. Much of the capture fisheries discussion focuses on coastal and marine fisheries. However, many of the approaches and principles presented apply as well to freshwater and inland fisheries found in most of the world’s lakes, rivers, and seasonal water bodies. The fisheries section of the guide focuses on nearshore marine and inland fisheries, as this segment of the industry employs more people and comprises a larger percentage of total catch, by weight and value, in most developing countries. The emphasis in the guide is on small-scale fisheries. That said, in many cases it is impossible to address problems of the small-scale sector without including analysis and simultaneous reforms in the large-scale industrial sector. The aquaculture section concentrates on reforming the sector for environmental, financial, and social sustainability, with an emphasis on food production for the poor and the utilization of local or native species. The introductory section also emphasizes the important linkages of capture fisheries and aquaculture to other sectors such as biodiversity conservation, economic growth, food security, and public health, as well as governance reform that supports participatory democracy and conflict mitigation.

    journal of international humanitarian legal studies 11 (2020) 295-310 brill.com/ihls Apocalypse Now? Initial Lessons from the Covid-19 Pandemic for the Governance of Existential and Global Catastrophic Risks Hin-Yan Liu, Kristian Lauta and Matthijs Maas Faculty of Law, University of Copenhagen, Copenhagen, Denmark [email protected]; [email protected]; [email protected] Abstract This paper explores the ongoing Covid-19 pandemic through the framework of exis- tential risks – a class of extreme risks that threaten the entire future of humanity. In doing so, we tease out three lessons: (1) possible reasons underlying the limits and shortfalls of international law, international institutions and other actors which Covid-19 has revealed, and what they reveal about the resilience or fragility of institu- tional frameworks in the face of existential risks; (2) using Covid-19 to test and refine our prior ‘Boring Apocalypses’ model for understanding the interplay of hazards, vul- nerabilities and exposures in facilitating a particular disaster, or magnifying its effects; and (3) to extrapolate some possible futures for existential risk scholarship and governance. Keywords Covid-19 – pandemics – existential risks – global catastrophic risks – boring apocalypses 1 Introduction: Our First ‘Brush’ with Existential Risk? All too suddenly, yesterday’s ‘impossibilities’ have turned into today’s ‘condi- tions’. The impossible has already happened, and quickly.

    Glossary of Biosecurity Management† A Abiotic stress (Cekaman abiotik) [Bio] Outside (nonliving) factors which can cause harmful effects to plants, such as soil conditions, drought. Absorbed dose (Dosis terserap) [Bio] Quantity of radiating energy (in gray) absorbed per unit of mass of a specified target. Action research (Penelitian tindakan) [Soc] (1) Kind of research methods that aims to contribute both to the practical concerns of people in an immediate problematic situation and to the goals of social science by joint collaboration within a mutually acceptable ethical framework; (2) a flexible spiral process which allows action (change, improvement) and research (understanding, knowledge) to be achieved at the same time. Action research is concerned to enlarge the stock of knowledge of the social science community. It is this aspect of action research that distinguishes it from applied social science, where the goal is simply to apply social scientific knowledge but not to add to the body of knowledge. †The compiler of the Glossary of Biosecurity Management is Professor Sang Putu Kaler Surata, one of the team members involved in authoring this book. The Glossary was prepared as a stand-alone publication in both English and Bahasa Indonesian languages in response to the lack of international clarity, consistency and information about terms related to biosecurity. The process and a great deal of detail about the Glossary and its preparation are contained in Professor Surata’s Chap. 7 of this volume, and additional detail regarding translation aspects is found in Ms Jayantini’s Chap. 8. Due to its cross-disciplinary and often contested nature, the Glossary of Biosecu rity Management draws on a wide range of sources.

In 2005, the Snohomish Basin Salmon Recovery Forum (Forum) adopted the Snohomish River Basin Salmon Conservation Plan1 (Salmon Plan), defining a multi-salmon strategy for the Snohomish Basin that emphasizes two ESA-listed species, Chinook salmon and bull trout, and the non-listed coho salmon. These species are used as proxies for other Basin salmon to help prevent future listings. The Salmon Plan, developed by the 41-member Forum, incorporates habitat, harvest, and hatchery management actions to bring the listed wild stocks back to healthy, harvestable levels. 1 Snohomish Basin Salmon Recovery Forum, 2005.

  • What Is a Bottom Trawl?
    What is a Bottom Trawl? Bottom trawls are a type of mobile fishing gear consisting of very large nets that are dragged on the seafloor to catch groundfish and other species. Bottom trawls are used in virtually all East Coast, West Coast and Alaska fisheries to catch shrimp and fish such as cod, flounder and rockfish. Trawls are used from shallow, inshore depths of 50-feet to extreme depths of 6,000-feet on the continental slope. The National Academy of Sciences found in its 2002 report, “Effects of Trawling and Dredging on Seafloor Habitats,” that U.S. trawlers have damaged over 230,000 square nautical miles of seafloor, an area greater than California. The most common type of bottom trawl in the United States is the otter trawl, in which the net is held open vertically by the force of water moving against two massive otter doors/boards. The trawl net can stretch 40-feet in height and spread over 200 feet wide between the doors, depending on factors such as the depth fished and the type of fish targeted. A large, fully-rigged net weighs well over a ton and requires a large, powerful boat to drag the net, particularly when loaded with a catch of hundreds or thousands of pounds of fish and bycatch (unwanted, non-target species) in the codend, or back of the net. The impact to the seafloor from trawling is a compound of the weight of the net and the forward momentum of the gear as it is dragged forward. The opening of a bottom trawl net is lined with floats on the headrope and with weighted ground gear on the footrope.

  • The Role of Sustainable Fisheries and Aquaculture for Food Security and Nutrition
    The Role of Sustainable Fisheries and Aquaculture for Food Security and Nutrition James Rohan CPA MBA WorldFish, FAO and World Resources Institute has conducted research recently which will support many of the questions suggested. Principles of sustainable business should be considered as the framework seeks to have minimal negative impact on the global or local environment, community, society, or economy,while achieving an industrious objective. Local environment will require an understanding of marine life and a model similar to planetary boundaries may promote education, research opportunities and continuous improvement principles. Many of the researchers have commented on the lack of research activity in this area and justifies the request by FSN for consideration. Rather than calories, I have proposed in the past a nutritional mass balance approach to recognise nutrition for health in food security. This would require consideration of yield and while some researchers have identified process capability, we should also explore product capability. Is nutrition compromised under stress or can it be enhanced with management? Over 90% of the world's living biomass is contained in the oceans, which cover 71% of the Earth's surface. At present, we harvest about 0.2% of marine production. ● Marine sources provide about 20% of the animal protein eaten by humans. Another 5% is provided indirectly via livestock fed with fish. ● 60% of fish consumption is by the developing world. ● The fishing enterprise employs some 200 million people worldwide. http://www.globalchange.umich.edu/globalchange2/current/lectures/fisheries/fisheries.html Data exists which suggests some fisheries are over and under exploited.

NIKOMEZE FINNISH INTERNATIONAL DEVELOPMENT AGENCY FOOD AND AGRICULTURAL ORGANIZATION OF THE UNITED NATIONS Bujumbura, January 1998 The conclusions and recommendations given in this and other reports in the Research for the Management of the Fisheries on the Lake Tanganyika Project series are those considered appropriate at the time of preparation. They may be modified in the light of further knowledge gained at subsequent stages of the Project. The designations employed and the presentation of material in this publication do not imply the expression of any opinion on the part of FAO or FINNIDA concerning the legal status of any country, territory, city or area, or concerning the determination of its frontiers or boundaries. PREFACE The Research for the Management of the Fisheries on Lake Tanganyika project (LTR) became fully operational in January 1992. It is executed by the Food and Agriculture Organization of the United Nations (FAO) and funded by the Finnish International Development Agency (FINNIDA) and the Arab Gulf Program for the United Nations Development Organization (AGFUND). LTR's objective is the determination of the biological basis for fish production on Lake Tanganyika, in order to permit the formulation of a coherent lake-wide fisheries management policy for the four riparian States (Burundi, Tanzania, Zaire and Zambia). Particular attention is given to the reinforcement of the skills and physical facilities of the fisheries research units in all four beneficiary countries as well as to the build-up of effective coordination mechanisms to ensure full collaboration between the Governments concerned.

  • Production System Design and Best Management Alternatives
    Research Project Investigations: Production System Design and Best Management Alternatives DEVELOPMENT OF LOW-COST AQUAPONIC SYSTEMS FOR KENYA- PART I Production System Design and Best Management Alternatives/Experiment/13BMA05AU Julius O. Manyala1, Kevin Fitzsimmons2, Charles Ngugi3, Josiah Ani1, and Elizabeth Obado1 1University of Eldoret, Kenya 2University of Arizona, USA 3Kenyatta University, Nairobi, Kenya ABSTRACT The activities of the University of Eldoret involved the designing and testing of small-scale low-cost aquaponics system that can be used for training and extension. This system is specifically suitable for small-scale fish hobbyists in water deficient situations and urban/semi urban areas where land is scarce. The small-scale was developed and its efficiency assessed using different fish stocking densities. The small-scale aquaponic system consisted of a rectangular fish culture tank rising to 460 mm from the bottom and a plant bed rising to 270 mm from a raised platform, both units being arranged in a vertical tier. Water overflow from the fish unit was passed through a bio-filter made of shredded plastic material to increase the surface area. These units acted as a nitrification chamber before the water was flowed by gravity into the plant beds. The effluent water from the plant beds was pumped back to the fish tank units using a submersible lift pump for the small-scale system as shown in the appendices. Water discharge from the plant unit flows back to the fish unit by gravity thereby elimination the need for double pumping in the small-scale system. The prototype units were constructed at University of Eldoret and were tested using all male tilapia (Oreochromis niloticus) fry for 42-105 days to the fingerling and juvenile stages.

  • Groundwater As Essential Salmon Habitat in Nushagak and Kvichak River Headwaters: Issues Relative to Mining
    Groundwater as Essential Salmon Habitat In Nushagak and Kvichak River Headwaters: Issues Relative to Mining Dr. Carol Ann Woody and Dr. Brentwood Higman for CSP2 10 July 2011 Groundwater as Essential Salmon Habitat in Nushagak and Kvichak River Headwaters: Issues Relative to Mining Dr. Carol Ann Woody Fisheries Research and Consulting www.fish4thefuture.com Dr. Brentwood Higman Ground Truth Trekking http://www.groundtruthtrekking.org/ Abstract Groundwater-fed streams and rivers are among the most important fish habitats in Alaska because groundwater determines extent and volume of ice-free winter habitat. Sockeye, Chinook, and chum salmon preferentially spawn in upwelling groundwater, whereas coho prefer downwelling groundwater regions. Groundwater protects fish embryos from freezing during winter incubation and, after hatching, ice-free groundwater allows salmon to move both down and laterally into the hyporheic zone to absorb yolk sacs. Groundwater provides overwintering juvenile fish, such as rearing coho and Chinook salmon, refuge from ice and predators. Groundwater represents a valuable resource that influences salmon spawning behavior, incubation success, extent of overwintering habitat, and biodiversity, all of which can influence salmon sustainability. Recently, over 2,000 km2 of mine claims were staked in headwaters of the Nushagak and Kvichak river watersheds, which produce about 40% of all Bristol Bay sockeye salmon (1956-2010). The Pebble prospect, a 10.8 billion ton, low grade, potentially acid generating, copper deposit is located on the watershed divide of these rivers and represents mine claims closest to permitting. To assess groundwater prevalence and its relationship to salmon resources on mine claims, rivers within claims were surveyed for open ice-free water, 11 March 2011; open water was assumed indicative of groundwater upwelling.

  • Sustainable Seafood Campaign
    Sustainable Seafood Campaign Overfishing and destructive fishing are among the most significant threats facing our oceans. The UN reports that three-quarters of global fish stocks are either fully exploited or overexploited. Scientists estimate that 90% of top marine predators such as tuna and sharks are already gone. Pirate fishing, estimated to account for up to a third of the global catch, is notorious for targeting at-risk populations and using highly destructive methods. Destructive fishing indiscriminately kills “non-target” species, including marine mammals and seabirds, and destroys habitats that marine species depend on for survival. In addition to the direct and cascading effects on marine ecosystems, overfishing and destructive fishing make our ocean ecosystems more vulnerable to global warming. If current trends continue, scientists predict global fisheries will collapse in forty years. U.S. consumers buy half their seafood at supermarkets, to the tune of $16 billion every year. As consumer interest in sustainable products has grown, so have retailer efforts to promote their eco-friendly initiatives. Yet, few supermarkets have made significant efforts to improve their seafood sustainability. Greenpeace is calling on supermarkets to sell only sustainable seafood and to support positive reforms in fisheries management. By doing so, supermarkets will do their part to help avert the crisis facing our oceans while ensuring their customers quality fish from sustainable fisheries for years to come. Supermarkets have enormous purchasing power, and are well positioned to influence the way the fishing industry operates. What You Can Do! Greenpeace needs your help monitoring supermarket seafood policies and practices. The information you gather will be used to update our supermarket scorecard.

Lawrence Piper www.TheAnglersMark.com [email protected] 904-557 -1027 Table of Contents Tackle and Angling Page 2 Fish and Fishing Page 5 Fishing Spots Page 13 Trailering and Boating Page 14 General Page 15 1 Amelia Island Back Country Light Tackle Fishing Tips Tackle and Angling 1) I tell my guests who want to learn to fish the back waters “learn your knots”! You don’t have to know a whole bunch but be confident in the ones you’re going to use and know how to tie them good and fast so you can bet back to fishing after you’ve broken off. 2) When fishing with soft plastics keep a tube of Super Glue handy in your tackle box. When you rig the grub on to your jig, place a drop of the glue below the head and then finish pushing the grub up. This will secure the grub better to the jig and help make it last longer. 3) Many anglers get excited when they hook up with big fish. When fishing light tackle, check your drag so that it’s not too tight and the line can pull out. When you hookup, the key is to just keep the pressure on the fish. If you feel any slack, REEL! When the fish is pulling away from you, use the rod and the rod tip action to tire the fish. Slowly work the fish in, lifting up, reeling down. Keep that pressure on! 4) Net a caught fish headfirst. Get the net down in the water and have the angler work the fish towards you and as it tires, bring the fish headfirst into the net.

An introduction to the Theme Section on fisheries bycatch Candan U. Soykan1,*, Jeffrey E. Moore2, Ramunas ¯ 5ydelis2, Larry B. Crowder2, Carl Safina3, Rebecca L. Lewison1 1Biology Department, San Diego State University, 5500 Campanile Dr., San Diego, California 92182-4614, USA 2Center for Marine Conservation, Nicholas School of the Environment, Duke University Marine Laboratory, 135 Duke Marine Lab Road, Beaufort,North Carolina 28516, USA 3Blue Ocean Institute, PO Box 250, East Norwich, New York 11732, USA ABSTRACT: Several high-profile examples of fisheries bycatch involving marine megafauna (e.g. dolphins in tuna purse-seines, albatrosses in pelagic longlines, sea turtles in shrimp trawls) have drawn attention to the unintentional capture of non-target species during fishing operations, and have resulted in a dramatic increase in bycatch research over the past 2 decades. Although a number of successful mitigation measures have been developed, the scope of the bycatch problem far exceeds our current capacity to deal with it. Specifically, we lack a comprehensive understanding of bycatch rates across species, fisheries, and ocean basins, and, with few exceptions, we lack data on demographic responses to bycatch or the in situ effectiveness of existing mitigation measures. As an introduction to this theme section of Endangered Species Research ‘Fisheries bycatch: problems and solutions’, we focus on 5 bycatch-related questions that require research attention, building on exam- ples from the current literature and the contributions to this Theme Section.
