Coastal Indigenous peoples rely on ocean resources and are highly vulnerable to ecosystem and economic change. Their challenges have been observed and recognized at local and regional scales, yet there are no global-scale analyses to inform international policies. We compile available data for over 1,900 coastal Indigenous communities around the world representing 27 million people across 87 countries. Based on available data at local and regional levels, we estimate a total global yearly seafood consumption of 2.1 million (1.5 million-2.8 million) metric tonnes by coastal Indigenous peoples, equal to around 2% of global yearly commercial fisheries catch. Results reflect the crucial role of seafood for these communities; on average, consumption per capita is 15 times higher than non-Indigenous country populations. These findings contribute to an urgently needed sense of scale to coastal Indigenous issues, and will hopefully prompt increased recognition and directed research regarding the marine knowledge and resource needs of Indigenous peoples. Marine resources are crucial to the continued existence of coastal Indigenous peoples, and their needs must be explicitly incorporated into management policies., Competing Interests: The authors have declared that no competing interests exist.

The magenta policy is the reactive policy (fishers increasing total effort when catch is low, decreasing to the minimum encountered in the data if the annual yield is negative). Our work highlights a new framework that embraces the complex processes that drive fisheries population dynamics yet produces simple and robust advice to ensure long-term sustainable fisheries.

Fishers' economic status is hard to assess because fisheries socio‐economic data, including earnings, are often not centrally available, standardized or accessible in a form that allows scaled‐up or comparative analyses. The lack of fishing income data impedes sound management and allows biased perceptions about fishers' status to persist. We compile data from intergovernmental and regional data sets, as well as case‐studies, on income earned from marine wild‐capture fisheries. We explore the level and distribution of fishers' income across fisheries sectors and geographical regions, and highlight challenges in data collection and reporting. We find that fishers generally are not the poorest of the poor based on average fishing income from 89 countries, but income levels vary widely. Fishing income in the large‐scale sector is higher than the small‐scale sector by about 2.2 times, and in high‐income versus low‐income countries by almost 9 times. Boat owners and captains earned more than double that of crew and owner‐operators, while income from fisheries is greater than that from agricultural work in 63% of countries in this study. Nonetheless, incomes are below national poverty lines in 34% of the countries with data. More detailed fishing income statistics is needed for quantitative scientific research and for supporting socio‐economic policies. Key gaps to address include the lack of a centralized database for fisheries income statistics and the coarse resolution at which economic statistics are reported internationally. A first step to close the gap is to integrate socio‐economic monitoring and reporting in fisheries management. [ABSTRACT FROM AUTHOR]

Climate change, mismanaged resource extraction, and pollution are reshaping global marine ecosystems with direct consequences on human societies. Sustainable ocean development requires knowledge and data across disciplines, scales and knowledge types. Although several disciplines are generating large amounts of data on marine socio-ecological systems, such information is often underutilized due to fragmentation across institutions or stakeholders, limited standardization across scale, time or disciplines, and the fact that information is often not searchable within existing databases. Compiling metadata, the information which describes existing sets of data, is an effective tool that can address these challenges, particularly when metadata corresponding to multiple datasets can be combined to integrate, organize and classify multidisciplinary data. Here, using Mexico as a case study, we describe the compilation and analysis of a metadatabase of ocean knowledge that aims to improve access to information, facilitate multidisciplinary data sharing and integration, and foster collaboration among stakeholders. We also evaluate the knowledge trends and gaps for informing ocean management. Analysis of the metadatabase highlights that past and current research in Mexico focuses strongly on ecology and fisheries, with biological data more consistent over time and space compared to data on human dimensions. Regional imbalances in available information were also evident, with most available information corresponding to the Gulf of California, Campeche Bank and Caribbean and less available for the central and south Pacific and the western Gulf of Mexico. Despite existing knowledge gaps in Mexico and elsewhere, we argue that systematic efforts such as this can often reveal an abundance of information for decision-makers to develop policies that meet key commitments on ocean sustainability. Surmounting current cross-scale social and ecological challenges for sustainability requires transdisciplinary approaches. Metadatabases are critical tools to make efficient use of existing data, highlight and address strengths and deficiencies, and develop scenarios to inform policies for managing complex marine social-ecological systems.

Fisheries catches are known to be widely underreported, and much of their value flows in informal markets. Goods and services that are not directly sold in a market also have a corresponding economic value, here termed ‘shadow value’, which can apply to discarded fish—or those that are consumed but not sold (e.g., subsistence catches). Here, we estimate the monetary value of fisheries catches in Panama that are landed but not reported, or that are discarded at sea; this includes catches from artisanal and industrial fleets, as well as recreational and subsistence fisheries. Based on available data, we estimate that the market and shadow value of unreported catches in Panama in 2010 was around US$92 million, equal to approximately 43% of the total reported landed value. In the case of discarded fish, the shadow value represents the potential but entirely unrealized economic benefit of landing such fish; in the case of unreported landings, unreported market value represents only the first link in the potentially sophisticated informal seafood economy. One must be careful in considering these results for policy. It is possible that, rather than seeking to capture these ‘lost’ benefits, fish that are discarded or unreported should not have been caught at all, for example, if they are juveniles or of threatened species; conversely, unreported subsistence catches are crucial for food security throughout the world. These results help contextualize the scale of unreported fisheries in economic terms, and can inform subsequent policies and strategies to ensure social, ecological, and economic sustainability.

Fisheries management in northwestern Mexico must fully recognize fisheries as part of socio-ecological systems. This study describes the evolution and status of fisheries management, including the interaction dynamics of management institutions with conservation organizations, and highlights the opportunities and challenges involved in achieving ecological and social sustainability. In this context, recognizing artisanal fisheries as a social, as well as economic, activity would facilitate the evolution of governance and management systems towards greater alignment with social objectives. This approach allows us to fully address key issues, including the challenges that indigenous fishing communities face and the expected impacts of climate change. The scientific knowledge and experience accumulated over five decades provides a significant capacity to develop new strategies for transitioning towards greater system sustainability. The success of this process will depend on the ability to consolidate a unified vision of desired benefits, particularly for fishing communities. [ABSTRACT FROM AUTHOR]

Harmful fisheries subsidies contribute to overfishing leading to environmental and societal impacts. If only fisheries and ecosystems within the subsidising nations' jurisdiction were affected, then unilateral actions might be sufficient to help safeguard our ocean and the people reliant upon it. However, just as fish move between jurisdictions, so too do the subsidised fishing fleets that target them. As such, the impacts and solutions to subsidies-induced overfishing are often matters of international concern. Mapping the distribution and flows of harmful subsidies is therefore key to understanding these concerns, informing multilateral reform, and empowering impacted nations to strengthen the terms of access to their waters and resources. Here we quantify the amount of harmful fisheries subsidies that supports fishing in the high seas, domestic and foreign waters. We estimate that between 20% and 37% of all harmful fisheries subsidies support fishing in foreign waters or the high seas, that is outside the jurisdictions of the subsidising nations. We show that harmful subsidies primarily originate from nations with high-Human Development Index (HDI), strong fisheries management capacity and relatively sustainable fish stocks, yet disproportionately impact nations with low or very low-HDI, lower management capacity and more vulnerable fish stocks—40% of the harmful subsidies that support fishing in very low-HDI nations waters originate from high-HDI and very-high HDI nations. We show that Asia, Europe, and North America, are net subsidy sources; they provide more harmful subsidies to their fishing fleets than their respective ecosystems are impacted by; while Africa, South, Central America and Caribbean, and Oceania are net subsidy-sinks. This discrepancy between the source of harmful subsidies and the nations that are ultimately impacted is unsustainable and unjust. Prohibiting all harmful subsidies to distant-water fishing and fishing in the high seas—with narrow exceptions for Small Island Developing States—should be prioritised to support the advancement of sustainable and equitable fisheries worldwide. • We quantify the amount of harmful subsidies supporting fishing in the high seas, domestic and foreign waters. • Between 20% and 37% of harmful subsidies support fishing in foreign waters or the high seas. • Harmful subsidies unequally affect low or very low-HDI nations, with low management capacity and vulnerable fish stocks. • Asia, Europe and N. America are net subsidy sources; providing more harmful subsidies than their ecosystems are affected by. • Marine ecosystems within Africa, Oceania, South, Central America, and Caribbean, are net subsidy-sinks.

Subsidies can directly support unsustainable fishing practices that harm both ecosystems and long-term social and economic benefits. Global fishery subsidies are substantial, yet their impacts on fishing dynamics are specific to given regions or fisheries at local scales. Subsidies thus have markedly different effects when applied to artisanal versus industrial, or managed versus open-access conditions, as shown for Mexican fisheries. Subsidy reform strategies are critically assessed, drawing on a review of over 30 case studies worldwide to determine patterns in their usefulness and conditions for implementation. Strategies with best relative results are reorienting subsidies away from capacity-enhancement, and/or conditioning them on specific sustainable performance metrics. Decoupling subsidies from fishing (e.g. providing direct aid to fishers) has unpredictable and unclear results, whereas buyback programs tend to have poor outcomes. Eliminating subsidies is perhaps the simplest strategy, but is the most difficult to implement from a social and political perspective. Key factors for any policy to succeed are clear short- and long-term goals; creative design; transparent implementation; and strong socio-political will. [ABSTRACT FROM AUTHOR]

The announcement of plans for exploratory oil drilling at a number of offshore sites in Belize raised concerns about the risks associated with drilling, particularly given the socio-economic importance of the marine ecosystem. The current economic value of fisheries and marine ecotourism is estimated, along with the potential revenue from offshore oil and potential economic losses stemming from oil pollution, under various assumptions on risk and uncertainty. Marine fisheries and ecotourism are estimated to generate around US$ 183 million per year. Single-year estimated maximum revenue is higher for oil extraction initially but quickly declines; during a 50 year (two generation) period, total discounted benefits from marine fisheries and ecotourism are estimated at US$ 5.1 billion, compared to US$ 3.2 billion from offshore oil revenue. Following a hypothetical oil spill, discounted losses in marine fisheries and ecotourism due to perception and ecological impacts are estimated at US$ 912 million, with clean-up costs and capital losses of US$ 6.1-10.4 billion. Considering the short extraction life of oil resources compared to fisheries and ecotourism, the difference in benefits increases substantially in favour of the latter with a longer time horizon. A recent public referendum resulted in a 98% vote against oil exploration and a subsequent annulment of oil concessions pending environmental impact assessments. [ABSTRACT FROM AUTHOR]

Labor issues and human rights violations have become the subject of rising concern in fisheries and seafood production. This paper reviews recent research on labor issues in the fishing industry, especially by environmental researchers and nongovernmental organizations (NGOs) which are emerging as key players in research and policy arenas. Recent research has focused largely on severe violations such as forced labor, particularly in 'hotspot' geographies, often relying on indicators and risk-based approaches given the paucity of data and challenges of monitoring working conditions. This paper proposes that decent work – a concept associated with the institutional history of the International Labor Organization (ILO) but with broad implications – can contribute to overcoming gaps in the research landscape, and assessing and improving a range of labor issues in fisheries. The paper elaborates some key considerations for studying and promoting decent work in the seafood industry. Assessing and achieving decent work in the world's fisheries requires (1) a holistic human rights approach to decent work, in which labor concerns are understood in the context of interrelated and interdependent sets of human rights, (2) consideration of the complex political-economic regimes and histories in which seafood production is embedded, and perhaps most importantly, (3) that workers play a central role and have a voice in defining and achieving decent work. The paper concludes with future directions for research and a discussion of promising and emerging policy pathways for promoting decent work in fisheries and seafood production. • Attention is growing on labor issues in fisheries and seafood production. • Recent research focuses largely on severe abuses in hotspot geographies. • Focus is also on harvest stage of production and using indicators and risk-analysis. • Decent work is a holistic, comprehensive concept that can guide future work. • Multiple governance and policy pathways for promoting decent work are examined.

Harmful fisheries subsidies have historically contributed to fleet overcapacity and continue to be allocated to the fishing industry to artificially maintain its profitability. However, in this contribution we show that removing harmful subsidies and reducing overfishing will help to recover the resource biomass, subsequently leading to increased levels of sustainable catches, income and well-being of fishers, and reduces inequities in income and consumption when fish stocks are not effectively managed. Maintaining harmful fisheries subsidies is socially and economically inefficient. Taking the example of the EU fishing fleet, one of the largest fishing fleets in the world, we use the total factor productivity to show that small-scale fishing fleet's productivity is almost two-fold in the North Atlantic and 16% higher in the Mediterranean and Black seas compared to large-scale vessels. This result is explained because the harmful fisheries subsidies disproportionately allocated to large-scale vessels introduce distortions in the efficient allocation of inputs. With critical WTO negotiations ongoing regarding the global rules on fisheries subsidies, the EU must take advantage of the opportunity to lead a desirable transformative change while also supporting developing nations to truly achieve global sustainable and equitable fisheries.

November 2021 could see members of the World Trade Organization (WTO) reach an agreement to prohibit harmful fisheries subsidies, culminating over 20 years of negotiation and discussion. This commentary highlights strengths and places where the current draft text can be improved to ensure the agreement truly contributes to sustainable and equitable fisheries. Overall, conditionalities and exemptions are better streamlined and defined, time periods to enter into compliance are allowed yet reasonably short, types of subsidies to be particularly avoided are clearly noted, and appropriate emphasis is placed on reducing impacts from distant-water and transboundary fishing fleets. Key places for improvement relate to unspecific language on supporting fisher incomes, the uniform handling of illegal, unreported, and unregulated fisheries (IUU), and transparency in distant water fisheries, issues partly stemming from historical definitions that are useful for some fisheries but may not capture the complexity of others. Capacity-enhancing subsidies should be avoided, and it is important to avoid further negative impacts on marginalized fisher populations. Given the importance of reaching an agreement without further delay, we urge members to proactively and inclusively formalize their fishing definitions and practices to prevent inequitable outcomes for vulnerable fishers during the implementation stage of a new agreement. A WTO agreement to prohibit harmful fisheries subsidies is an opportunity to catalyze the design and funding of improved and cooperative national and international fisheries policy and management strategies, to the benefit of fishers, global seafood production, and indeed all who hold relationships with our oceans.

Amid declining shark populations because of overfishing, a burgeoning shark watching industry, already well established in some locations, generates benefits from shark protection. We compile reported economic benefits at shark watching locations and use a meta-analytical approach to estimate benefits at sites without available data. Results suggest that, globally, c. 590,000 shark watchers expend > USD 314 million per year, directly supporting 10,000 jobs. By comparison, the landed value of global shark fisheries is currently c. USD 630 million and has been in decline for most of the past decade. Based on current observed trends, numbers of shark watchers could more than double within the next 20 years, generating > USD 780 million in tourist expenditures around the world. This supports optimistic projections at new sites, including those in an increasing number of shark sanctuaries established primarily for shark conservation and enacted in recognition of the ecological and economic importance of living sharks.

Abstract: It is well recognized that not all fisheries catches are reported or recorded properly by either government or non-government agencies. These unreported catches can be illegal, of unregulated species, or simply not monitored due to logistical barriers. In Mexico, these barriers are an extensive and often not easily accessible coastline, mostly de facto open access fisheries, poor administrative practices and generalized corruption in the fishing sector as a whole. These conditions were likely promoted early in the last century through the government''s largely successful policies to increase fisheries catches and stimulate employment and economic growth. Many years later and amid declines in fish stocks and subsequent economic benefits, most notably at local scales, it is evidently time for a fundamental change in strategy away from expansion of fishing effort and toward ecological and economic sustainability. An important step in this endeavor is to provide a quantitative pre-mortem analysis of Mexico''s total marine fisheries catches during the last half-century. Results suggest that from 1950 to 2010, total catches were nearly twice as high as the official reports, with an average annual catch of 1.5 million tonnes (t) compared to 796thousandt in official statistics. In the last year of available data, 2010, official and total estimated catches were 1.5million and 2.2milliont, respectively. While these results may be perceived as a criticism of the status quo and ante, this study actually does not single out a responsible party, but is, rather, a call to the many sectors of society who contribute to a lack of control, to help overcome these conditions, and increase and sustain the benefits from Mexico''s marine fisheries.

Marine oil spills usually harm organisms at two interfaces: near the water surface and on shore. However, because of the depth of the April 2010 Deepwater Horizon well blowout, deeper parts of the Gulf of Mexico are likely impacted. We estimate the potential negative economic effects of this blowout and oil spill on commercial and recreational fishing, as well as mariculture (marine aquaculture) in the US Gulf area, by computing potential losses throughout the fish value chain. We find that the spill could, in the next 7 years, result in (midpoint) present value losses of total revenues, total profits, wages, and economic impact of US$3.7, US$1.9, US$1.2, and US$8.7 billion, respectively. Commercial and recreational fisheries would likely suffer the most losses, with a respective estimated US$1.6 and US$1.9 billion of total revenue losses, US$0.8 and US$1.1 billion in total profit losses, and US$4.9 and US$3.5 billion of total economic losses.

The trajectory of the cannonball jellyfish (Stomolophus sp. 2) fishery in the central portion of Mexico's Gulf of California is an all too familiar one, consisting of exploration, rapid development, and, as of now, subsequent collapse. As all of the product is exported to markets overseas, buyers have little incentive to conserve local stocks, with jellyfish now exhibiting a global-scale sequential exploitation experienced by many other marine resources. While historical data gaps are often used as excuses for overexploitation after the fact, the emergence of this modern fishery was accompanied by relatively broad research interest; however, recommendations based on sound science were not followed. The resultant paucity of policy goals, regulation, cooperation, compliance, and enforcement has resulted in the mismanagement of a potentially lucrative fishery for future generations. There are always myriad challenges when attempting to manage a nascent fishery with high uncertainty, particularly in a developing country, and this case further highlights the importance of taking a precautionary approach to emerging resource extraction. Multiple prior experiences with similar outcomes should behoove regulators and managers to exhibit extra caution, and yet, sustainability and forethought still appear to be secondary to short-term profits and employment support. Nonetheless, it is perhaps not too late for cannonball jellyfish fisheries in the Gulf of California, and there are opportunities to implement management strategies that promote collaboration, research, and sustainability. This fishery requires a new management regime that embraces adaptive co-management in order to provide benefits to locals, both now and in the future. • Jellyfish are targeted for food exports in Mexico's Gulf of California. • Catches for one of the targeted species have declined, possibly due to overfishing. • Management challenges are complex due to natural and social factors. • Future strategies should include stakeholder collaboration and adaptive co-management.

The demand for fish maw (i.e., dried swim bladder) has apparently intensified during the past decades in Hong Kong and mainland China; currently, maw has similar annual import volumes but far higher mean unit values than other important seafood delicacies like shark fins and sea cucumber. Escalated demand for seafood delicacies can significantly contribute to the depletion of marine resources; yet a comprehensive understanding of maw value and the fisheries that supply it is lacking. We review available information on eight important maw-supplying species in major and largely undocumented source countries to examine the susceptibility and exposure of fisheries to the maw trade, which primarily serves Chinese demand. Comparing ex-vessel price ratios of maw to flesh (USD/kg), the overall mean price of maw can be as much as 72 times higher (range between 12:1 and 8389:1). Catch, price and export trends demonstrate that demand for maw is likely intensifying in countries already supplying it, shifting or expanding to new species, and emerging in new regions. We find that most maw-supplying species are under high fishing pressure, poorly or not protected. Those that yield the highest maw prices exhibit spawning aggregations, making them exceptionally vulnerable to overexploitation. While management interventions are needed to sustain fishery resources and capture economic benefits, their effectiveness will be challenged by the high value of maw. [ABSTRACT FROM AUTHOR]

The World Trade Organization (WTO) is in the final stages of negotiating an agreement to prohibit harmful fisheries subsidies, thereby achieving UN Sustainable Development Goal (SDG) 14.6. An effective agreement should be viewed as an opportunity for nations to proactively transition towards sustainable and equitable fisheries and pave the path for other SDGs. Supporting fishers does not require harmful subsidies, and we provide evidence-based options for reform that highlight equity needs while reducing environmental harm. Subsidy reforms need clear goals, co-design, transparency, and fair implementation. An agreement on SDG 14.6 could be a turning point for the oceans and for the well-being of those that depend on the oceans for livelihoods and nutrition. Responsible seafood production will require international cooperation not only at WTO, but among governments, fisher organizations, civil society, and the wider public. [ABSTRACT FROM AUTHOR]

• More transboundary fish stocks are expected under climate change, complicating fisheries management. • Linked game theory—ecosystem models test ecosystem-based co-management strategies. • Cooperative, ecosystem-based management of Pacific sardine improves profitability over all fisheries. • Managers must account for the key role of forage fish for ecosystems as well as other fisheries. Transboundary fish stocks complicate sustainable fishing strategies, particularly when stakeholders have diverse objectives and regulatory and governance frameworks. Pacific sardine (Sardinops sagax) in the California Current is shared by up to three fishing nations— Canada, the United States, and Mexico—and climate-driven abundance and distribution dynamics can complicate cooperative fisheries, leading to overfishing. This study builds on previous analyses by integrating ecosystem linkages into a game theory model of transboundary sardine fisheries under various climate scenarios. Cooperative fishing strategies that account for the ecosystem-wide value of sardine as forage for other species result in increased economic benefits compared to strategies that only account for the single-species value of sardine fisheries to a given fishing country. Total ecosystem landed value is maximized at a sardine fishing rate only somewhat lower than sardine F MSY , which is more precautionary but still allows the fishery to operate. Incorporating ecosystem dynamics into management-applicable models can highlight ways in which ecosystem-based fisheries management can improve both sustainability and profitability and help managers prioritize wider ecological research. Ecosystem-based management will be increasingly required to understand and adapt to the observed rapid shifts in species distributions due to climate change, and to design strategies to achieve sustainable and profitable fisheries amidst changing ecosystems.

The World Trade Organization's (WTO) has committed to achieving a multilateral and legally binding agreement to eliminate fisheries subsidies that contribute to overcapacity and overfished stocks, and to illegal, unreported, and unregulated fisheries. This agreement is due in December of 2019 and also represents UN Sustainable Development Goal 14.6. A strong agreement would benefit fishers and marine environments, represent a milestone for multilateralism and both international and national fisheries policy, and become the first global achievement of a SDG target. To help discussions and negotiations focus on real challenges, we briefly dispel five myths related to harmful fisheries subsidies. Harmful fisheries subsidies are not effective at competing with large fishing nations and worsen poverty in the long-term. The worst effects of harmful subsidies occur when management capacity is limited, and overexploitation and overcapacity in one region can impact others. Because most global stocks are already exploited at least at maximum sustainable levels, more fishing capacity is unnecessary. Turning away from harmful subsidies can enable new investments to benefit fishing communities, national economies, and marine ecosystems. [ABSTRACT FROM AUTHOR]
