First, Find Fish While salmon, cod, and tuna fisheries are regularly monitored assessed, this is not the case for about 80% of fish species harvested throughout world. Costello et al. (p. 517 published online 27 September; see Perspective by Pikitch ) used a model that integrates harvest, population, ecological data to estimate status unassessed fisheries, based on ecologically analogous, assessed fisheries. Generally, in worse condition with declining stocks compared
Significance What would extensive fishery reform look like? In addition, what be the benefits and trade-offs of implementing alternative approaches to fisheries management on a worldwide scale? To find out, we assembled largest-of-its-kind database coupled it state-of-the-art bioeconomic models for more than 4,500 around world. We that, in nearly every country world, recovery simultaneously drive increases food provision, profits, fish biomass sea. Our results suggest that suite providing...
The world's oceans supply food and livelihood to billions of people, yet species' shifting geographic ranges changes in productivity arising from climate change are expected profoundly affect these benefits. We ask how improvements fishery management can offset the negative consequences change; we find that answer hinges on current status stocks. poor many stocks combined with potentially maladaptive responses range shifts could reduce future global fisheries yields profits even more...
Abstract The argument persists that the continued overexploitation by many fisheries around world is evidence current approaches to management are failing, and more precautionary needed. We review available estimates of status fish stocks from three sources: FAO's “State Marine Resources”, a database on scientific stock assessments, recent statistical models designed determine unassessed stocks. two key results (i) scientifically assessed in better shape indeed not typically declining but...
Sustainable development aspires to "leave no one behind"1. Even so, limited attention has been paid small-scale fisheries (SSF) and their importance in eradicating poverty, hunger malnutrition. Through a collaborative multidimensional data-driven approach, we have estimated that SSF provide at least 40% (37.3 million tonnes) of global catches 2.3 billion people with, on average, 20% dietary intake across six key micronutrients essential for human health. Globally, the livelihood 1 every 12...
Abstract The exploitation status of marine fisheries stocks worldwide is critical importance for food security, ecosystem conservation, and fishery sustainability. Applying a suite data‐limited methods to global catch data, combined through an ensemble modeling approach, we provide quantitative estimates 785 fish stocks. Fifty‐three percent (414 stocks) are below B MSY these, 265 estimated be 80% the level. While 149 above conventionally considered “fully exploited,” staying at this level...
Significance The incidental catch of threatened species is still one the main barriers to fisheries sustainability. What would happen if we closed 30% ocean fishing with goal reducing bycatch? Analyzing 15 different around globe, found that under static area management, such as classic no-take marine closures, observed bycatch could be reduced by 16%. However, dynamic management based on and closing same total but fragmented in smaller areas can move year year, reduction increase up 57% at...
Abstract Fishery managers must often reconcile conflicting estimates of population status and trend. Superensemble models, commonly used in climate weather forecasting, may provide an effective solution. This approach uses predictions from multiple models as covariates additional “superensemble” model fitted to known data. We evaluated the potential for ensemble averages superensemble (ensemble methods) improve trend fisheries. fit four widely applicable data‐limited that estimate stock...
Marine protected areas (MPAs) cover 3-7% of the world's ocean, and international organizations call for 30% coverage by 2030. Although numerous studies show that MPAs produce conservation benefits inside their borders, many are also justified on grounds they confer to connected populations span beyond borders. A network covering roughly 20% Channel Islands National Sanctuary was established in 2003, with a goal providing regional fishery benefits. We used spatially explicit bioeconomic...
Changes in the marine environment, particularly climate change, can have large effects on distribution patterns of various species, and alter biodiversity, structure functions affected ecosystems. Species models (SDM) are tools often used to link species' ecological niches with their environment. We applied SDM investigate five biologically relevant climatic variables from multiple databases, including bottom temperature, salinity, current velocity, depth primary productivity, habitat...
Abstract Implementation of the United Nations Sustainable Development Goals requires assessments global state fish populations. While we have reliable estimates stock status for populations accounting approximately half recent catch, our knowledge majority world's “unassessed” stocks remains highly uncertain. Numerous publications produced these unassessed fisheries, but limited quantity and quality data along with methodological differences counterintuitive conflicting results. Here, show...
Abstract Understanding the status of fish stocks is a critical step in ensuring ecological and economic sustainability marine ecosystems. However, at least half global catch vast majority fisheries lack formal stock assessments, largely due to sufficient data. Catch data, loosely referring any records be it inclusive discards or not, are only type fishery data available across wide range scale. This has given rise long list so‐called “catch‐only” models, intended estimate aspects based...
Abstract Many marine species are shifting their distributions in response to changing ocean conditions, posing significant challenges and risks for fisheries management. Species distribution models (SDMs) used project future the face of a climate. Information fit SDMs generally comes from two main sources: fishery‐independent (scientific surveys) fishery‐dependent (commercial catch) data. A concern with data is that fishing locations not independent underlying abundance, potentially biasing...
Reductions in global fishing pressure are needed to end overfishing of target species and maximize the value fisheries. We ask whether such reductions would also be sufficient protect non-target threatened as bycatch. compare changes profits from 4713 fish stocks-accounting for >75% catch-to reverse ongoing declines 20 marine mammal, sea turtle, seabird populations project that maximizing fishery halt or approximately half these populations.

We compile global data to examine the current status, trends, threats, and opportunities in world's wild-capture fisheries. find that fisheries have largely diverged—well-managed, often industrial tend be reasonably good health, while coastal fisheries, from low-governance regions, poor health. Good governance seems play a central role, we summarize key findings literature on how effective fishery management can simultaneously increase food security, livelihoods, conservation outcomes. Other...
Abstract The pelagic fisheries beyond the continental shelves are currently managed with a range of tools largely based on regulating effort or target catch. These comprise both static and dynamic area‐based approaches to include gear limitations, closed areas bycatch limits. There increasing calls for additional interventions, particularly expansion marine protected areas, many now advocating closing 30% oceans fishing. In this paper, we review objectives, methods successes management blue...
Abstract Climate change is projected to affect the productivity of global fisheries. Management based on maximum sustainable yield (MSY) has been effective at eliminating overfishing in many regions. However, continuing use yield‐maximizing targets under climate‐driven changes can result higher anthropogenic pressure populations subject climate‐related stress than maintaining status quo management targets. We demonstrate this effect using a theoretical example and case studies from snow crab...
Abstract Well‐managed fisheries support healthy ocean ecosystems, coastal livelihoods and food security for millions of people. However, many communities lack the resources to implement effective management. No‐take marine reserves are a ubiquitous management intervention that provide conservation benefits under certain circumstances can long‐term fishery as result larval adult emigration from reserve boundaries. But, by participants is often limited due short‐term economic impacts resulting...
Population dynamic models are widely used to predict demography. However, they have rarely been extended biogeographical applications despite widespread calls do so. We developed a process-based range model (DRM) that estimated demographic rates and the effects of environment on forecast species shifts in response temperature change. As proof concept, we fitted DRMs historical observations summer flounder (Paralichthys dentatus), fish Northwest Atlantic, evaluated skill at retrospective...
