Endophytes, foliage inhabiting fungi, are an unexplored source of fungal biodiversity and a potential resource for the production of bioactive natural products. In this research, leaf tissues from the species Arbutus menziesii, Rhododendron macrophyllum and the genus, Ilex and Salix were collected for the isolation of endophytic fungi. Fungal extracts...
Postpartum uterine inflammation (endometritis) is not uncommon in beef cattle, resulting in infertility and culling. Prolonged calving may contribute to the increased incidence of endometritis in heifers. Commonly used methods to treat endometritis in beef cattle include intrauterine antibiotics and/or hormone injections, which can result in meat residues. Platelet rich...
Recent international negotiations have highlighted the need to protect marine diversity on the high seas—the ocean area beyond national jurisdiction. However, restricting fishing access on the high seas raises many concerns, including how it would impact food security. Here we analyze high seas catches and trade data to determine the...
A series of session stakeholder presentations will address the current status, challenges, needs and future perspectives for implementation of management and ecological / economic assessment of data poor fish stocks and fisheries in management advice. This covers methods, simulation models and management strategy evaluation (MSE) tools to conduct assessment and...
Fisheries development projects are undertaken ever year in recognition of the important role fisheries play in many coastal communities. The objectives vary, but typically go beyond a limited focus on fisheries management and the ecosystem. This makes it difficult to evaluate the contribution of a project, particularly in data poor...
We present the results of integrating the fisheries sector into an existing computable partial-equilibrium global model of agriculture, livestock, bioenergy, forestry, and land use. The model is constructed by reconciling publicly available global datasets from the FAO as well as the literature. The model of the fish sector represents capture...
While buybacks don’t have the cache of rights-based programs they are often pre-cursors to longer-term management solutions. The authors assess a proposed buyback program in Eastern Pacific (EPO) purse seine fishery that has the potential to increase post-buyback profitability, and which could also provide the means to alleviate long-standing internecine...
As fisheries management is increasingly required to consider the full impacts of their operations, this work seeks to define the relationship between fishing effort and interactions with listed endangered species. The study employs logbook data containing over 64,000 sets, matched with observer data from 2008 to 2015 in an undisclosed...
In 2015, baseline expenditure and trip behavior information about angler activity across a 14-county region of California’s Central Valley was collected. The motivation for this study was twofold: to learn about existing recreational fishing levels in the Sacramento River system, and to understand how these levels might change if fishing...
Poaching is a major problem under the Chilean system of territorial use rights in fisheries (TURFs). Organizations of artisanal fishers that are granted spatial property rights through TURFs combat poaching by establishing their own enforcement. Although an organization must protect its benthic resources against poachers from both within the organization...
A growing practice in fisheries management is the allocation access rights to marine fisheries through individual transferable quota (ITQs) – limits on the amount of fish allocated to individual licences as transferable permits. By establishing an ownership claim over the right to fish and a market for exchange, ITQs are...
Climate projections indicate that ocean temperatures will continue increasing, potentially shifting the distribution of marine fish species and affecting the economics of the fishing industry and fishing communities. In this study, an integrated ecological-economic framework is used to evaluate the economic impacts of climate-driven species changes and assesses the value...
The status of fishing industry participants and fishing communities is an increasingly important consideration in marine ecosystem models and in fisheries management. Metrics that reliably measure economic, health, and other dimensions of human well-being are required to analyze the impacts of changes in marine ecosystems and policy. To date, most...
In the European Union (EU), marine resource management policies and legislation include not only environmental objectives but also a broad range of explicitly stated economic, social and institutional (ESI) goals, objectives and priorities. Although the environmental objectives often guide scientific assessments, the ESI objectives are often the primary drivers of...
This paper discusses the importance of the fishing industry – fishing fleet and processing industry – for the development of coastal communities. Statistical analysis is performed to analyze the importance of development in the fisheries sector (catch, landings, employment et.c) and how and to what degree this explains the growth...
The focus of this study is the development of the Icelandic trawler fleet and the drivers behind the changes. The first stern trawlers began operation in 1970, five years later there were 58 fishing in the EEZ and in 1982 their number reached above 100. Excess capacity and overcapitalization characterized...
The Florida reef ecosystem is a highly valuable resource managed by multiple federal and state agencies with many stakeholders. Over half of the $75 million annual dockside value of finfish landings in Florida is comprised of snappers and groupers, but this resource is threatened by overfishing. Current management strategies include...
In Norway, structuring of the fishing fleet has been an ongoing process since the start of the 1960'ies. Since then, both the number of vessels in Norwegian fisheries and fishers have been reduced by roughly 85 %. For decades, the fisheries industry has been considered a mean to employment and...
Fisheries products are the worlds most widely traded foods. Despite the fact that global demand for fish and fishery products continues to rise every year, fish export from the developing world have faced many limitation from non-conformity with international standards to inadequate product certification. As international fisheries trade grows, governments,...
The feed conversion ratio (FCR) or its reciprocal, the feed efficiency ratio (FER) is currently used to estimate the feed requirements in aquaculture. This has a serious disadvantage. The FCR is a function of feeding rate, initial and final mass at fattening, temperature and quality of feed. Therefore the FCR...
How well at fishery management regime perform is closely related both to vessel performance (i.e. return on investments) and if the species at stake are harvested in sustainable manner. However, ROI do not capture important dimensions of vessel performance. In addition, sustainability also includes social, economic and institutional dimensions. In...
Fishers exploit populations that are heterogeneously distributed in space and time without full knowledge of species distributions and with fishing gear that is not fully selective. The ability to change catch composition is limited by species mix at a particular location and time and the capture characteristics of the fishing...
A primary objective of fishery management is profit maximization, accomplished by managing externalities associated with catching fish, while acknowledging that some margins of fishing fall beyond regulatory bounds. Regulation often does not address the larger economy of which the fishery is a part, focusing instead on the cost--benefit structure of...
Fisheries economics has recently earned a seat at the global fisheries governance table, with everything from subsidies, to high seas fisheries, to Indigenous rights, food security, and human rights now being open for global assessment. The papers in which these studies are housed are in high impact journals, are highly...
This paper examines the regulatory decision problem facing fishery managers tasked with balancing desirable fish catch with undesirable bycatch. I approach the problem using Bayesian decision analysis. I first estimate a model of production, accounting for the fishery’s joint production of desirable and undesirable outputs. I then use the estimated...
Iceland had several disputes with its neighboring countries during the fifties, sixties and seventies over expansions of sovereign waters and control of fishing rights, known as the cod wars. Iceland was successful in securing exclusive fishing rights for its people. However, the problem of overexploitation, which lay at the heart...
Socio-economic analysis of seafood production is important for the conservation of aquatic ecosystems and the management of fisheries and aquaculture activities. Understanding how the livelihoods of people, dependent on the exploitation of aquatic resources, are affected by various changes is essential for decision making. The two main seafood production sectors,...
Based on a simple model of firm profit maximisation in a multispecies ITQ fishery, market clearing quota lease prices are modelled as a system of linear equations with dimensions dependent upon the number of quota species in the fishery and the number of different harvesting technologies. Finding a set of...
Climate change has been observed to have a significant impact on the distribution of aquatic species and productivity of aquaculture systems across the globe. This affects the level of food production, the livelihoods of communities that depend on fisheries and aquaculture, and the future sustainability of these sectors. As in...
The fisheries sector faces the challenge of determining effective management, in an ecosystem perspective in order to mitigate the Global Warming Potential (GWP).The main focus of the study was to analyze the resource utilization in the value chain of Maldives fish processing and the environmental performances of the steps involved....
The fisheries sector is a vital oceanic resource that build the core of the Blue Economy. However the realization of the full potential of the Blue Economy calls the requirement of effective inclusion of all societal groups, especially women whose contribution is not well acknowledged. The study focused to investigate...
In Nigeria, women play major roles of at least 75% in the fisheries and aquaculture value- chains from production, processing, storage, marketing and trade. Unlike the men, women have not received commensurate levels of attention and empowerment largely because their roles are perceived as ‘invisible’, poorly evaluated and undocumented without...
Stated choice random utility frameworks are a valuable tool for eliciting the preferences of fishermen. In typical applications, choice outcomes are known prior to choice selection, which may confound results when outcomes are uncertain. To evaluate the importance of uncertainty in decision making, we applied a contingent sequential stated choice...
Sophisticated computer simulations can support effective science-based evaluations to facilitate better governance of the marine space. We developed a range of spatial fisheries models, integrating biological with fisher decision-making dynamics and management for assessing management of multiple activities. We present the outcomes of case-specific evaluations with different ecological and socio-economic...
The first-hand market for wild-caught fish in Norway is subject to much uncertainty for both buyers and sellers. Factors such as changing quotas, seasonal variations in availability of important species, and sudden changes in market conditions creates instability in volumes and prices both on the demand and supply side. For...
Indonesian tuna fisheries are complex due to variation in the scale of fleet in the fisheries, their multi-species nature and problems with data collection. Moreover, like many developing-country fisheries, their management needs to take into account many other goals besides rents maximization, such as the distribution of rents and the...
The importance of land infrastructure for supporting coastal fisheries has long been acknowledged; its role in remote and geographically challenged fishing communities in the Nordic Arctic has visibly impacted community structure and development. This paper explores the Red King Crab (RKC) fishery in Norway and the ways in which its...

This project has received funding from the European Union’s Horizon 2020 Research and Innovation programme. PrimeFish engages a large Industry Reference Group (IRG) that facilitates the access...
Implemented in 2011, the West Coast Groundfish Trawl Catch Share Program was designed to achieve multiple economic goals and objectives for a diverse multispecies fishery, including increasing net benefits, profitability, flexibility, and utilization of harvest allocations. Here, we leverage seven years of comprehensive cost and earnings data to evaluate progress...
The importance of small-pelagic species in marine ecosystems and their economic contribution to coastal communities are increasingly recognised by many fishery managers. However, the management of small pelagic species faces many challenges due to environmental factors that periodically impact on recruitment of the species. Delayed responses in management to these...
The ‘blob’ of anomalously warm surface water that persisted in the North Pacific Ocean from 2013-2016 resulted in a massive harmful algal bloom (HAB) of Pseudo-nitzschia along the entire U.S. west coast. The bloom produced record-breaking concentrations of domoic acid, a marine neurotoxin, that contaminated seafood and necessitated fisheries harvest...
Regulators in many countries have adopted quotas as a means of dealing with the open access problem inherent in fisheries. Unit quotas for the Norwegian purse seine fleet were introduced in 1996 but consolidation of licenses has been in place since 1978. The current Norwegian regulatory system does allow for...
We present a bottom-up analysis of the proportion of global marine fisheries subsidies to small-scale fisheries (SSF). Using existing data, we split the reported national subsidy amounts into the fraction that goes to small- compared to large-scale fishing sectors. Results reveal a major imbalance in subsidy distribution, with SSF receiving...
This study develops a dynamic model of the harvesters’ choice of when to use individual fishing quota (IFQ), considering time-varying rates of potentially limiting bycatch, and a time-varying outside opportunity. The temporal allocation of IFQ over a season by harvesters has not been well-studied empirically due to complexity of the...
Even in the absence of commercial fishing, Coho salmon (Onchorhynchus kisutch) originating from the Interior Fraser River (IFR) watershed have yet to recover from the low returns experienced since 1992. Coho are in a low productivity regime in which the number of recruits per spawner (R/S) averages around one, coupled...
Feedbacks between the ecosystem and the economy are important to consider when measuring impacts from a disturbance but are often missed in representations of the economy and the food web. Moreover, regional general equilibrium models often focus on how humans respond to ecological changes and do not consider that in...
Coho salmon (Oncorhynchus kisutch) were once a thriving species in Southern British Columbia, providing cultural, economic and ecological benefits to First Nations and coastal communities. Nonetheless, with Coho salmon abundance starting to dwindle dramatically in the 1990s, the Department of Fisheries and Oceans (DFO) decided to implement radical conservation measures...
Sablefish is a commercially important species with catch allocated across multiple sectors and gear types on the U.S. West Coast. A flexibility provision in the West Coast Groundfish Trawl Catch Share Program sanctions those with trawl permits to target Sablefish with fixed gear, such as longlines or pots, allowing the...
What is the impact of the recent spike in Eastern Atlantic and Mediterranean bluefin tuna catch on the global price of bluefin and its substitutes? Will boosting the eastern bluefin quota even further benefit the fishing industry? And who stands to win and lose from supply increases? Using a novel...
European seabass and gilthead seabream are two economically important cultured fish species along the Mediterranean coast. Both species represent respectively 10.9% and 13.5% of the total value of the European aquaculture sector (Eurostat, 2013). The EU is one of the largest producers of seabass and seabream in the world, being...
In the North East Atlantic there are several straddling stocks, including herring, mackerel, and blue whiting, which are exploited both within coastal states' 200 nautical mile Exclusive Economic Zones (EEZ) and on the high seas. The pelagic fisheries of the North East Atlantic are all harvested by the same six...
Fishery management actions focused on the conservation of non-target species may impact the productivity of fisheries in terms of target species. This article studies California’s drift gillnet swordfish (Xiphias gladius) fishery and investigates the impact of a recent regulatory measure aimed to protect leatherback turtles. A parametric approach is used...
In the FPI framework, input indicators are those attributes expected to influence the outcomes of fishery management. One subset of those indicators is comanagement, measured by 11 input scores spread over four dimensions (collective action, participation, community, and gender). After applying FPIs to 13 Japanese coastal fisheries that varied in...
As changes in climate and corresponding ocean shifts threaten U.S. fisheries with uncertain change, West Coast marine scientists and fishery management institutions have newly emphasized ecosystem-based analysis and management. The development of the West Coast-specific California Current Integrated Ecosystem Assessment (CCIEA) has accordingly allowed for economic analyses and the social...
Catch shares are being increasingly adopted worldwide to halt overfishing and improve ecosystem outcomes. Rights-based fisheries management generates economic efficiency, and fishers with a financial stake in the fisheries are believed to have the incentive to become ecological stewards. However, the empirical evidence shows no significant impact of catch share...
Commercial fishing can provide a source of economic opportunities for coastal communities; however, little is known about how large such effects may be. In particular, there is limited empirical research on what indirect impact commercial fishing may have on local economic activity in other sectors through spillover/multiplier effects. While such...
The National Oceanic and Atmospheric Administration (NOAA) executes a number of activities that support a more holistic way of studying and managing marine resources, namely an ecosystem-based approach to management (EBM). This presentation will provide an overview of NOAA’s Integrated Ecosystem Assessment (IEA) program as well as Large Marine Ecosystem...
Managing internationally-shared fish stocks, those that migrate from one country’s coast to another is incredibly difficult and requires international cooperation. The International Commission for the Conservation of Atlantic Tunas (ICCAT) is the regulatory body responsible for managing tuna and tuna-like species in Atlantic and adjacent seas fisheries. Although ICCAT has...
The U.S. Atlantic pelagic longline fleet pursues highly migratory species (e.g., swordfish, tunas, and sharks) over an extensive range in the Atlantic, Gulf of Mexico, and Caribbean Sea. Because of the fleet’s diverse range and vessel characteristics, fuel can be a major component of vessel operating costs and can make...
Situation: UK scallop fishing is input measures, with effort limits applied to >15m vessels only. There are no output limits. Industry members noted a decline in profits, and suggested that the effort regime was to blame. Government asked for evidence to support the claim and asked Seafish for economic analysis...
Given the high pressure in fishing resources, the interest of going beyond the resources and understanding market trends, market barriers, and fisheries value-chain inequities, has increased in the last decade. This knowledge is necessary to improve those chains and to promote better financial returns for fishers and market participants, in...
Demand for science and advice to address economic considerations is increasing, but the International Council for the Exploration of the Seas (ICES) does not engage many economists or address economic issues in many member countries. The Strategic Initiative on the Human Dimension (SIHD) has raised the profile of economics, but...
The assessment of data-limited fish stocks is crucial for the sustainable management of marine living resources. Dependent on the scope and type of available data, a range of assessment methods are available, such as catch-only, length-based, or catch and survey-based methods. However, these methods suffer from several shortcomings, such as...
Understanding and quantifying the behavior of fishers is important given the role human behavior plays in fish population dynamics and fisheries management. Various quantitative and qualitative methods have been used to collect information on the behavior of fishers. This study discusses the benefits and drawbacks of three of these methods:...
Seafood is one of the most valuable and highly traded commodities worldwide, and thus highly susceptible to fraud. The Norwegian fisheries sector is subject to a wealth of regulatory requirements ensuring an environmentally and economically sound fishery. Nonetheless, studies have shown that there exists a, at times significant, discrepancy between...
A World Bank/Global Environmental Facility funded project aims to explore the potential for incentive based tools and third-party financing to improve the performance of highly migratory fisheries with a high seas component (ABNJ fisheries). Under this World Bank project, the World Wildlife Fund (WWF-Inc.) is responsible for the work of...
This paper is designed to “set the stage” for the Special Session on Game Theory and Fisheries. It traces the origins of the application of game theory to fisheries economics, noting that, for the first quarter of a century after the publication of H. Scott Gordon’s 1954 seminal article, the...
The Gulf of Mexico (GOM) is characterized by fishery resources which spatially and temporally overlap in different ways with several important non-fishing uses including oil and gas production, shipping, tourism, habitat for endangered species, and economic support for coastal communities. Given this overlap, the Deepwater Horizon Oil Spill affected fishing...
This study explores the optimal spatial strategy for fishing efforts for subdivided on fishing grounds for different economic performance. We analyze the Japanese off-shore longline fishing vessel groups targeting swordfish and blue shark in the North Pacific. The seasonal dynamic optimal spatial strategy to maximize the economic performance is explored...
Conservation impacts on protected sea turtles and marine mammals are a longstanding concern in U.S. swordfish fisheries, including the Hawaii shallow-set longline (SSLL) fishery and the west coast drift-gillnet (DGN) fishery. Observer records for these fisheries document a history of rare-event interactions with large cetaceans and endangered sea turtles. Since...
In France, the absence of further development of marine fish farming over the last 20 years has been attributed to regulatory constraints, and to the difficult access to new farming sites, due to high competition between different uses in the coastal zone. The Regional schemes for the development of marine...
Highly migratory species (tunas, billfish, swordfish, and sharks or HMS) are pursued by a dedicated group of anglers that spend significant amounts in pursuit of these “big game” fish. From 2013 to 2016, NOAA Fisheries conducted the most comprehensive assessment of the economic impacts of HMS recreational fisheries in the...
Data generating processes for trip-level commercial fishing data feature endogenous targeting of individual fish species and spatially, temporally varying stock conditions that are unobserved by the researcher but partially observed by fishermen. We present a model and identification strategy to address serious challenges that arise in this setting for obtaining...
Strategies for increasing production of goods from working and natural systems have raised concerns that the diversity of species on which these services depend may be eroding. This loss of natural capital threatens to homogenize global food supplies and compromise the stability of human welfare. We assess the trade-off between...
Despite an understanding among consumers that fish is a healthy food, the recommended intake is on average not achieved in many countries. This paper investigates the effect of children in households to the purchase of fish and meat products, using Norwegian household-level panel data on food purchases from 2004 to...
