    The concept of “blue growth,” which aims to promote the growth of ocean economies while holistically managing marine socioecological systems, is emerging within national and international marine policy. The concept is often promoted as being novel; however, we show that historical analogies exist that can provide insights for contemporary planning and implementation of blue growth. Using a case‐study

    Fisheries management aims to ensure that the fishing activities are environmentally sustainable in the long term, while also achieving the economic, social and food security related management objectives. To facilitate this, both the ecological and human dimensions of sustainability need to be included in fisheries assessment. In addition, assessing long‐term sustainability calls for taking into account

  • Identifying spawner biomass per‐recruit reference points from life‐history parameters

    Analysis of spawning biomass per‐recruit has been widely adopted in fisheries management. Fishing mortality expressed as spawning potential ratio (SPR) often requires a reference point as an appropriate proxy for the fishing mortality that supports a maximum sustainable yield—FMSY. To date, a single generic level between F30% and F40% is routinely used. Using records from stock assessments in the RAM

  • Tuna trade‐offs: Balancing profit and social benefits in one of the world’s largest fisheries
    Fish Fish. (IF 6.655) Pub Date : 2020-03-23
    Ciara Willis; Megan Bailey

    The western and central Pacific Ocean (WCPO) tuna fishery is one of the world's largest in terms of both catch volume and value, providing over half of global tuna catch with a landed value of US $5.84 billion in 2017. Fishing is conducted by both large‐ and small‐scale fleets, with fisheries subsidies disproportionately benefiting the former. The primary objective of this study was to determine the

  • The role of sand lances (Ammodytes sp.) in the Northwest Atlantic Ecosystem: A synthesis of current knowledge with implications for conservation and management

Llopiz; David Wiley; Irit Altman; Andew Applegate; Peter Auster; Hannes Baumann; Julia Beaty; Deirdre Boelke; Les Kaufman; Pam Loring; Jerry Moxley; Suzanne Paton; Kevin Powers; David Richardson; Jooke Robbins; Jeffrey Runge; Brian Smith; Caleb Spiegel; Halley Steinmetz

    The American sand lance (Ammodytes americanus, Ammodytidae) and the Northern sand lance (A. dubius, Ammodytidae) are small forage fishes that play an important functional role in the Northwest Atlantic Ocean (NWA). The NWA is a highly dynamic ecosystem currently facing increased risks from climate change, fishing and energy development. We need a better understanding of the biology, population dynamics

  • Spatio‐temporal analyses of marine predator diets from data‐rich and data‐limited systems

    Accounting for variation in prey mortality and predator metabolic potential arising from spatial variation in consumption is an important task in ecology and resource management. However, there is no statistical method for processing stomach content data that accounts for fine‐scale spatio‐temporal structure while expanding individual stomach samples to population‐level estimates of predation. Therefore

Holmes; Michel Kulbicki; Priscilla T. Y. Leung; Paul K. S. Lam;

    Canopy‐forming macroalgae can construct extensive meadow habitats in tropical seascapes occupied by fishes that span a diversity of taxa, life‐history stages and ecological roles. Our synthesis assessed whether these tropical macroalgal habitats have unique fish assemblages, provide fish nurseries and support local fisheries. We also applied a meta‐analysis of independent surveys across 23 tropical

  • Selectivity metrics for fisheries management and advice

    Fisheries management typically aims at controlling exploitation rate (e.g., Fbar) to ensure sustainable levels of stock size in accordance with established reference points (e.g., FMSY, BMSY). Population selectivity (“selectivity” hereafter), that is the distribution of fishing mortality over the different demographic components of an exploited fish stock, is also important because it affects both

  • Improving sustainable yield estimates for tropical reef fisheries
    Fish Fish. (IF 6.655) Pub Date : 2020-03-09
    Timothy R. McClanahan; Maxwell Kodia Azali

    Fishing sustainably is a fundamental problem in tropical regions where diverse fisheries and scarce fisheries information challenges efforts to make reliable estimates and associated policies. To improve evaluations and decisions, we compared the predictions of six surplus production models calibrated using various permutations of fisheries‐dependent data with a benchmark model. The benchmark model

  • The interim management procedure approach for assessed stocks: Responsive management advice and lower assessment frequency

    Stock assessments are often used to provide management advice, such as a total allowable catch (TAC), to fishery managers. Many stocks are not assessed annually, and the TAC from the previous assessment is often maintained in years between assessments. We developed two interim management procedures (MPs) that update the estimate of current vulnerable biomass from a surveyed index of abundance to adjust

  • The highs and lows of herring: A meta‐analysis of patterns and factors in herring collapse and recovery
    Fish Fish. (IF 6.655) Pub Date : 2020-03-03
    John T. Trochta; Trevor A. Branch; Andrew O. Shelton; Douglas E. Hay

    Pacific and Atlantic herring populations (genus Clupea) commonly experience episodic collapse and recovery. Recovery time durations are of great importance for the sustainability of fisheries and ecosystems. We collated information from 64 herring populations to characterize herring fluctuations and determine the time scales at low biomass and at high and low recruitment, and use generalized linear

    Freshwater capture fisheries are globally essential for food security and aquatic biodiversity conservation. The Yangtze River Basin is the third longest and one of the most human‐influenced drainage basins worldwide. Since the founding of P. R. China in 1949, this large river system has suffered increasing human perturbation and its sustainable development is now severely challenged. Meta‐analysis

  • Opportunities for agent‐based modelling in human dimensions of fisheries

Saul; Ingrid E. van Putten; Sharon Wilcox

    Models of human dimensions of fisheries are important to understanding and predicting how fishing industries respond to changes in marine ecosystems and management institutions. Advances in computation have made it possible to construct agent‐based models (ABMs)—which explicitly describe the behaviour of individual people, firms or vessels in order to understand and predict their aggregate behaviours

  • Using knowledge of behaviour and optic physiology to improve fish passage through culverts
    Fish Fish. (IF 6.655) Pub Date : 2020-02-28
    Matthew Jon Jones; Robin Hale

    Culverts reduce connectivity for aquatic animals by being both a hydraulic and physical barrier. However, altered light intensity may also be a behavioural barrier to fish movement, especially for diurnal species that have adapted to moving when it is light. We propose that knowledge of optical physiology and fish behaviour, two important mechanisms underpinning movement, can inform efforts to improve

  • Density‐dependent growth and survival in salmonids: Quantifying biological mechanisms and methodological biases
    Fish Fish. (IF 6.655) Pub Date : 2020-02-28
    Jean‐Michel Matte; Dylan J. Fraser; James W. A. Grant

    Understanding the complex variation in patterns of density‐dependent individual growth and survival across populations is critical to adaptive fisheries management, but the extent to which this variation is caused by biological or methodological differences is unclear. Consequently, we conducted a correlational meta‐analysis of published literature to investigate the relative importance of methodological

  • Are fishers poor? Getting to the bottom of marine fisheries income statistics
    Fish Fish. (IF 6.655) Pub Date : 2020-01-29
    Lydia C. L. Teh; Yoshitaka Ota; Andrés M. Cisneros‐Montemayor; Lucy Harrington; Wilf Swartz

    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

  • Saving large fish through harvest slots outperforms the classical minimum‐length limit when the aim is to achieve multiple harvest and catch‐related fisheries objectives
    Fish Fish. (IF 6.655) Pub Date : 2020-01-29
    Robert N. M. Ahrens; Micheal S. Allen; Carl Walters; Robert Arlinghaus

    We address the problem of optimal size‐selective exploitation in an age‐structured fish population model by systematically examining how density and size dependency in growth, mortality and fecundity affect optimal harvesting patterns when judged against a set of fisheries objectives. The study offers five key insights. First, while minimum‐length limits often maximize the biomass yield, exploitation

  • Southward re‐distribution of tropical tuna fisheries activity can be explained by technological and management change
    Fish Fish. (IF 6.655) Pub Date : 2020-01-28
    Iratxe Rubio; Unai Ganzedo; Alistair J. Hobday; Elena Ojea

    There is broad evidence of climate change causing shifts in fish distribution worldwide, but less is known about the response of fisheries to these changes. Responses to climate‐driven shifts in a fishery may be constrained by existing management or institutional arrangements and technological settings. In order to understand how fisheries are responding to ocean warming, we investigate purse seine

  • Changing how we approach fisheries: A first attempt at an operational framework for ecosystem approaches to fisheries management
    Fish Fish. (IF 6.655) Pub Date : 2020-01-22
    Jason S. Link; Geir Huse; Sarah Gaichas; Anthony R. Marshak

    The increasing need to account for the many factors that influence fish population dynamics, particularly those external to the population, has led to repeated calls for an ecosystem approach to fisheries management (EAFM). Yet systematically and clearly addressing these factors, and hence implementing EAFM, has suffered from a lack of clear operational guidance. Here, we propose 13 main factors (shift

  • Evolution of marine fisheries management in China from 1949 to 2019: How did China get here and where does China go next?
    Fish Fish. (IF 6.655) Pub Date : 2020-01-21
    Shu Su; Yi Tang; Bowen Chang; Wenbin Zhu; Yong Chen

    China is the world’s biggest fishing nation and a major player in the global seafood trade. Its fisheries development can decisively influence the global seafood trade, food security and marine conservation. In recent years, significant changes have taken place in China’s fisheries management priorities, policies and regulations. In this paper, we review the evolving fisheries management practices

    Ecosystem‐based management of fisheries aims to allow sustainable use of fished stocks while keeping impacts upon ecosystems within safe ecological limits. Both the FAO Code of Conduct for Responsible Fisheries and the Aichi Biodiversity Targets promote these aims. We evaluate implementation of ecosystem‐based management in six case‐study fisheries in which potential indirect impacts upon bird or mammal

    Small‐scale fisheries contribute substantially to the sustainability of coastal communities by providing livelihood and economic opportunities and ensuring food security. However, their geographic range of operation overlaps with that of industrial fisheries, increasing the resource competition, risk of vessel collision and inter‐sector conflicts, while jeopardizing the sustainability of fish stocks

  • A novel spatiotemporal stock assessment framework to better address fine‐scale species distributions: Development and simulation testing
    Fish Fish. (IF 6.655) Pub Date : 2019-12-30

    Characterizing population distribution and abundance over space and time is central to population ecology and conservation of natural populations. However, species distribution models and population dynamic models have rarely been integrated into a single modelling framework. Consequently, fine‐scale spatial heterogeneity is often ignored in resource assessments. We develop and test a novel spatiotemporal

    Conservation of apex predators is a key challenge both in marine and terrestrial ecosystems. The white shark is a rare but persistent inhabitant of the Mediterranean Sea and it is currently assessed as “critically endangered” in the region. However, the population trends and dynamics of this species in the area are still unknown. Little is known about white shark distribution, habitat use and population

  • Choosing best practices for managing impacts of trawl fishing on seabed habitats and biota

    Bottom trawling accounts for almost one quarter of global fish landings but may also have significant and unwanted impacts on seabed habitats and biota. Management measures and voluntary industry actions can reduce these impacts, helping to meet sustainability objectives for fisheries, conservation and environmental management. These include changes in gear design and operation of trawls, spatial controls

  • Migrations and movements of Atlantic tarpon revealed by two decades of satellite tagging

    Understanding large‐scale migratory behaviours, local movement patterns and population connectivity are critical to determining the natural processes and anthropogenic stressors that influence population dynamics and for developing effective conservation plans. Atlantic tarpon occur over a broad geographic range in the Atlantic Ocean where they support valuable subsistence, commercial and recreational

  • Tackling alcoholism and domestic violence in fisheries—A new opportunity to improve well‐being for the most vulnerable people in global fisheries
    Fish Fish. (IF 6.655) Pub Date : 2019-12-09

    The UN Sustainable Development Goals (SDGs) principle of “leaving no one behind” focuses global attention on the poorest and most vulnerable people. As different sectors grapple to engage meaningfully with this principle, we posit that greater consideration of social problems in fishing‐dependent communities, such as alcoholism and domestic violence, presents an opportunity for fishery governors to

  • The mitigation hierarchy for sharks: A risk‐based framework for reconciling trade‐offs between shark conservation and fisheries objectives
    Fish Fish. (IF 6.655) Pub Date : 2019-12-02
    Hollie Booth, Dale Squires, Eleanor Jane Milner‐Gulland

    Sharks and their cartilaginous relatives are one of the world's most threatened species groups. The primary cause is overfishing in targeted and bycatch fisheries. Reductions in fishing mortality are needed to halt shark population declines. However, this requires complex fisheries management decisions, which often entail trade‐offs between conservation objectives and fisheries objectives. We propose

  • Predicting optimal combinations of by‐catch reduction devices in trawl gears: A meta‐analytical approach
    Fish Fish. (IF 6.655) Pub Date : 2019-12-02
    Valentina Melli, Bent Herrmann, Junita Diana Karlsen, Jordan Paul Feekings, Ludvig Ahm Krag

    Global efforts to reduce unwanted catches have led to the development of a vast array of by‐catch reduction devices (BRDs), in particular for mixed trawl fisheries. Some of these BRDs could likely benefit from being combined. However, the number of possible combinations would be prohibitive to be tested experimentally. Therefore, in this study we propose a meta‐analytical approach that combines the

  • Predicting recruitment density dependence and intrinsic growth rate for all fishes worldwide using a data‐integrated life‐history model
    Fish Fish. (IF 6.655) Pub Date : 2019-11-29
    James T. Thorson

    Fisheries scientists use biological models to determine sustainable fishing rates and forecast future dynamics. These models require both life‐history parameters (mortality, maturity, growth) and stock‐recruit parameters (juvenile production). However, there has been little research to simultaneously predict life‐history and stock‐recruit parameters. I develop the first data‐integrated life‐history

  • What constitutes effective governance of recreational fisheries?—A global review

    The effectiveness of recreational fisheries governance has been mixed, with some countries boasting good governance practices that sustain productive recreational fisheries, while others lack any policies and governance structures specific to recreational fisheries. Here, we identify what constitutes effective governance of recreational fisheries by carrying out: (a) a desktop review of 227 country‐specific

  • Implications of fisheries‐induced evolution for population recovery: Refocusing the science and refining its communication
    Fish Fish. (IF 6.655) Pub Date : 2019-11-18
    Jeffrey A. Hutchings, Anna Kuparinen

    The argument that sufficiently high fishing mortality (selective or not) can effect genetic change in fished populations has gained considerable traction since the late 1970s. The intervening decades have provided compelling experimental and model‐based evidence that fisheries‐induced evolution (FIE) can cause genetic changes in life history, behaviour and body shape, given sufficiently high trait

Pierre, Claude Dykstra, Jan Jaap Poos

    Since the beginning of the 21st century, electronic monitoring (EM) has emerged as a cost‐efficient supplement to existing catch monitoring programmes in fisheries. An EM system consists of various activity sensors and cameras positioned on vessels to remotely record fishing activity and catches. The first objective of this review was to describe the state of play of EM in fisheries worldwide and to

    The increasingly complex nature of marine resource management calls for stronger stakeholder participation in advancing knowledge and developing management approaches. Studies on stakeholder involvement in marine resource management have primarily focussed on participation in resource use negotiation and not on participation in science. Using fishers' knowledge research frameworks, we evaluate over

  • Scavenger communities and fisheries waste: North Sea discards support 3 million seabirds, 2 million fewer than in 1990
    Fish Fish. (IF 6.655) Pub Date : 2019-11-08
    Richard B. Sherley, Hannah Ladd‐Jones, Stefan Garthe, Olivia Stevenson, Stephen C. Votier

    Every year fisheries discard >10 million tonnes of fish. This provides a bounty for scavengers, yet the ecological impact of discarding is understudied. Seabirds are the best‐studied discard scavengers and fisheries have shaped their movement ecology, demography and community structure. However, we know little about the number of scavenging seabirds that discards support, how this varies over time

  • The impact of solar ultraviolet radiation on fish: Immunomodulation and photoprotective strategies
    Fish Fish. (IF 6.655) Pub Date : 2019-11-06
    Karl P. Lawrence, Antony R. Young, Brian L. Diffey, Mary Norval

    One of the many environmental factors affecting the health of both farmed and wild fish is exposure to solar ultraviolet radiation (UVR). These rays penetrate to biologically relevant depths in natural waters and cause changes ranging from embryo malfunction to the production of heat‐shock proteins. As suppression of cell‐mediated immunity has been shown to follow irradiation of mammals, the possibility

    Small‐scale fisheries often involve weak management regimes with limited top‐down enforcement of rules and minimal support from legal institutions, making them useful model systems for investigating the role of social influence in determining economic and environmental outcomes. In such regimes, interpersonal relationships are expected to have a strong effect on a fisher's catch portfolio, the set

    China is the world's largest capture fisheries and aquaculture producer. Over recent decades, China's domestic marine catch composition has changed markedly, from large volumes of a few high‐valued food species to multiple, small, low‐valued, species, a significant proportion of which is primarily used as animal, especially fish, feed. Despite the growing volume and economic importance of the feed

  • No room for dessert: A mechanistic model of prey selection in gut‐limited predatory fish
    Fish Fish. (IF 6.655) Pub Date : 2019-10-24
    Johanna Fall, Øyvind Fiksen

    Predatory fish structure communities through prey pursuit and consumption and, in many marine systems, the gadoids are particularly important. These predators have flexible feeding behaviours and often feed on large prey items. Digestion times of large prey are usually longer than handling times, and gut processing limits feeding rate at high prey density. Optimizing the gut content mix can therefore

  • Ecosystem‐based fisheries management: A perspective on the critique and development of the concept
    Fish Fish. (IF 6.655) Pub Date : 2019-10-24
    Susanna Lidström, Andrew F. Johnson

    The concept of ecosystem‐based fisheries management (EBFM) has been subjected to debate since it was introduced in the late 1990s. The development of the concept seems to follow two separate but simultaneous trajectories of increased popularity but also sustained critique. This paper offers an analysis of potential mechanisms behind these disparate trajectories by drawing on a theoretical framework

    Wild capture fisheries provide substantial input to the global economy through employment and revenue. The coastal zone is especially productive, accounting for just 7% of the total area of the ocean, but supporting an estimated 50% of the world's fisheries. Vegetated coastal ecosystems—seagrass meadows, tidal marshes and mangrove forests—are widely cited as providing nutritional input that underpin

Frisk, Irene Kingma, Sophy R. McCully Phillips, Colman O'Criodain, Denham Parker, Samuel Shephard, Javier Tovar‐Ávila, Kotaro Yokawa

    International trade in vulnerable marine species is regulated once they are listed in CITES Appendices (the Convention on International Trade in Endangered Species of Wild Fauna and Flora). Parties to the Convention submit proposal(s) 150 days prior to the CITES Conference for voting on the inclusion of new species in Appendices I and II, making a case for why CITES listing criteria are met in each

  • Species range shifts along multistressor mosaics in estuarine environments under future climate

    Range shifts are a key mechanism that species employ in response to climate change. Increasing global temperatures are driving species redistributions to cooler areas along three main spatial axes: increasing latitudes, altitudes and water depths. Climate‐mediated range shift theory focuses on temperature as the primary ecological driver, but global change alters other environmental factors as well

    The growing awareness of the impact that recreational fishers can have on fish stocks has highlighted the paucity of information used to inform their management. Most of the available information on the scale and nature of recreational catch and effort has come from intermittent and labour‐intensive surveys that provide fragmented insights into often highly variable fisheries. Digital cameras offer

    Inland capture fisheries provide food for nearly a billion people and are important in the livelihoods of millions of households worldwide. Although there are limitations to evaluating many of the contributions made by inland capture fisheries, there is growing recognition by the international community that these services make critical contributions, most notably to food security and livelihoods in

  • Attending to spatial social–ecological sensitivities to improve trade‐off analysis in natural resource management

    Balancing trade‐offs amongst social–ecological objectives is a central aim of natural resource management. However, objectives and resources often have spatial dimensions, which are usually ignored in trade‐off analyses. We examine how simultaneously integrating social–ecological benefits and their spatial complexities can improve trade‐off analysis. We use Pacific herring (Clupea pallasii, Clupeidae)—an

    The role of inland fisheries in livelihoods, food security and sustainable development is often overshadowed by the higher profile interest in ocean issues. Whilst inland fisheries' catch and contribution to global nutrition, food security and the economy, are less than that of marine fisheries, global‐level comparisons of fish production obscure considerable livelihood impacts in certain countries

    Multispecies models are widely used to evaluate management trade‐offs arising from species interactions. However, identifying climate impacts and sensitive habitats requires integrating spatial heterogeneity and environmental impacts into multispecies models at fine spatial scales. We therefore develop a spatio‐temporal model of intermediate complexity for ecosystem assessments (a “MICE‐in‐space”)

    Age‐ or length‐structured stock assessments require reliable life history demographic parameters (growth, mortality, reproduction) to model population dynamics, potential yields and stock sustainability. This study synthesized life history information for 84 commercially exploited tropical reef fish species from Florida and the U.S. Caribbean (Puerto Rico and the U.S. Virgin Islands). We attempted

  • Inclusion of discards in stock assessment models

    A large portion of the catch in many stocks may comprise discards which need to be accounted for in assessments in order to avoid bias in estimates of fishing mortality, stock biomass and reference points. In age‐structured assessment models, discards are sometimes treated as a separate fleet or are added to the landings before fitting so that information about discard behaviour and sampling error

  • Estimates of fishing gear loss rates at a global scale: A literature review and meta‐analysis

    Abandoned, lost or otherwise discarded fishing gear (ALDFG) represents a significant, yet ultimately unknown amount of global marine debris, with serious environmental and socioeconomic impacts. This study reviews 68 publications from 1975 to 2017 that contain quantitative information about fishing gear losses. Gear loss estimates reported by the studies ranged widely, with all net studies reviewed

    Small‐scale fisheries provide food and livelihoods for thousands of people along the Brazilian coastline. However, considerable uncertainties still surround the extent to which artisanal and subsistence fisheries contribute to the total of national landings and their historical ecological significance. Fisheries monitoring is deficient in Brazil, and historical records are limited to irregular accounts

  • A critical appraisal of appendage disparity and homology in fishes

    Fishes are both extremely diverse and morphologically disparate. Part of this disparity can be observed in the numerous possible fin configurations that may differ in terms of the number of fins as well as fin shapes, sizes and relative positions on the body. Here, we thoroughly review the major patterns of disparity in fin configurations for each major group of fishes and discuss how median and paired

  • Hazards of managing disparate species as a pooled complex: A general problem illustrated by two contrasting examples from Hawaii

    Surprisingly little published information exists on the pros and cons of managing extracted resources that are pooled as compound taxa such as species complexes. Current fisheries management includes many species complexes; in Hawaii, this includes two taxa of species pooled at subfamily and higher levels. These include seven species of parrotfishes (Scarinae, Labridae) and a seven‐species ‘bottomfish’

  • Shifting perceptions of rapid temperature changes’ effects on marine fisheries, 1945–2017

    Climate‐driven warming has both social and ecological effects on marine fisheries. While recent changes due to anthropogenic global warming have been documented, similar basin‐wide changes have occurred in the past due to natural temperature fluctuations. Here, we document the effects of rapidly changing water temperatures along the United States’ east coast using observations from fisheries newspapers

  • Trait‐based ecology of fishes: A quantitative assessment of literature trends and knowledge gaps using topic modelling

    Species traits are a new data currency to enhance our understanding of ecological patterns and processes. Trait‐based studies of fishes are numerous in comparison with other animal groups, reflecting the diversity of fish forms and functions they provide to aquatic ecosystems. We conduct a retrospective examination of literature to identify knowledge gaps and provide guidance for future research in

  • Environmental influences on life history strategies in partially anadromous brown trout (Salmo trutta, Salmonidae)

    This paper reviews the life history of brown trout and factors influencing decisions to migrate. Decisions that maximize fitness appear dependent on size at age. In partly anadromous populations, individuals that attain maturity at the parr stage typically become freshwater resident. For individual fish, the life history is not genetically fixed and can be modified by the previous growth history and

    Analysing how fish populations and their ecological communities respond to perturbations such as fishing and environmental variation is crucial to fisheries science. Researchers often predict fish population dynamics using species‐level life‐history parameters that are treated as fixed over time, while ignoring the impact of intraspecific variation on ecosystem dynamics. However, there is increasing

  • Developmental temperature affects phenotypic means and variability: A meta‐analysis of fish data

    Fishes are sensitive to their thermal environment and face an uncertain future in a warming world. Theoretically, populations in novel environments might express greater levels of phenotypic variability to increase the chance of surviving—and eventually thriving—in the new conditions. Most research on the effect of the early thermal environment in fish species focuses on average phenotypic effects

  • How do commercial fishing licences relate to access?

    Commercial fishing licences are central to fisheries management systems. They define and allocate harvest rights, place rules upon authorized harvesters and, in some cases, require holders to pay user fees. In this paper, we ask how licences and licensing relate to access, itself a broader concept defined as the opportunity to derive benefits from resources and that draws attention to how institutions
