Birds, mammals, and fish eat Atlantic Herring. For the first time, fisheries managers in New England are explicitly considering these, and other, predators when setting harvest control rules for the Atlantic Herring fishery. Based on single-species biological reference points, the herring stock is currently well above MSY levels. However, management...
The landing obligation in Europe has been in place since January 1st 2015. Experiences gained so far point out that a number of institutional initiatives have been launched, but in practice little has changed regarding discard reduction and use of discards ashore. In parallel, the wide-ranging EU research project H2020...
Many of the world’s most valuable fisheries involve highly migratory stocks that cross national jurisdictions. These same fisheries face severe threats from direct overfishing or excessive bycatch. Traditional input and/or output controls generally have been costly and ineffective. Incentive-based programs that provide tradable shares in an annual total allowable catch...
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...
Due to establishment of five international organizations for tuna fisheries, tuna fishing in high seas are consequentially transformed from a time of free competition to a time of cooperative competition on the platforms created by those international organizations. The paper explores the openness, procedures of decision-making, allocation of fishing quotas...
Complex social–ecological systems such as small-scale fisheries require the inclusion of human dimensions in fisheries management and planning for simultaneously preserving human health and habitat health. However, linkages between ecological, social, political and economic subsystems have been largely ignored in conventional fisheries management, in Nigeria in particular. Hence, the weak...
The study contains a cost benefit analysis of the aquaculture development component of the Fish Farming Enterprise Productivity Program (FFEPP) undertaken for Meru County in Kenya. It focuses on the implementation of the FFEPP undertaken from 2009 up to 2013 and evaluates its benefits and costs against the opportunity cost...
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...
Focus groups were combined with surveys to inform policy making regarding precautionary measures to protect cold water coral (CWC). CWC represent complex environmental public goods involving irreversibility and uncertainty. Respondents believe CWC is valuable and should be protected. Use-values, particularly habitat for fish, dominated the focus group discussions, whereas non-use...
The Pacific sardine (Sardinops sagax) has been one of the most abundant fish in the California Current Ecosystem (CCE) since the late 1990s. In recent years under a warm regimen, large Pacific sardine reached Canadian waters in mid-June and returned to the spawning ground in Southern California during October. The...
Granting catch shares to cooperatives is a fisheries management option that has been widely applied. Although fishery cooperatives systems around the world are structured in various ways, it appears that most share the characteristic that members of the same cooperative are jointly and severally liable for not exceeding collectively assigned...
This research examines the gendered livelihood implications of fisheries management decisions through an exploration of a seasonal ban on fishing. The 45 day closed fishing season on the Eastern coast of India began in 2001 and applies to mechanized boats. While there is existing research on the impact of the...
Western Australian (WA) fisheries have a long association with environmental certification- the WA rock lobster fishery (in 2000) was the first fishery certified under the Marine Stewardship Council (MSC) standards.In 2012 the Western Australia Minister of Fisheries announced that the State Government had committed $14.6 million across a four-year period...
The recent history of fisheries management in New England has seen substantial interannual variability in total allowable catches (TACs), with stocks deemed healthy in one year retroactively identified as overfished soon thereafter. Concurrently, avenues for and examples of coordination between fishermen are increasing in the region, as exemplified by the...
Conflicts over the use of coastal areas are expected to increase in Norway in the future. In Northern Norway, salmon aquaculture and marine fishing tourism are expected to expand, affecting both the space available for other uses and ecosystems, including traditionally harvested fish stocks. While data is available to managers...
This paper addresses adverse incentives built into the process of TAC setting as an instrument to prevent overfishing in multispecies fisheries. Under the Magnuson Stevens Act (MSA), the primary law governing marine fisheries management in U.S. federal waters, regional Fishery Management Councils must develop a rebuilding plan for every overfished...
A quarter of biomass losses in Scottish marine Atlantic salmon aquaculture are attributable to infectious disease. Interventions to reduce the consequences of disease include the use of disease-resistant stock, vaccines and other authorised medicines, functional feeds, and modified farm management strategies. There are, however, only a few evaluations of the...
Proceedings of the Eighteenth Biennial Conference of the International Institute of Fisheries Economics and Trade, held July 11-15, 2016 at Aberdeen Exhibition and Conference Center (AECC), Aberdeen, Scotland, UK.
Australian governments spend millions of dollars each year on pre-border, border and post-border biosecurity programs. The majority of these programs are resourced through existing deeds of agreement, but some currently fall outside of these funding frameworks. Frameworks not based on economic principles have the potential to deliver sub-optimal outcomes with...
Production data from the red grouper fishery, Mexico, were analyzed to determine the production function. Three different models were tested in cross-sectional data from the period 1988 to 2014. The data were collected from the logbooks provided by skippers. Number of fishermen (crew) per trip varied from 3 to 15,...
Pelagic fish stocks are subject to fluctuations that are driven by climate change, overfishing and changes in market conditions. The fluctuating nature of pelagic fisheries creates uncertainties in fishers’ income, thereby adversely affecting their livelihoods. The aim of this contribution is to reduce the risk and vulnerability fishers face by...
Background: Fish are an important part of a well-balanced diet as it contains high quality proteins, as well as polyunsaturated fatty acids that are known to play an important role in human health. Consumption of fish, however, is the primary route of exposure to methylmercury in humans. A quantitative risk-benefit...
Dominant models of harvester behavior typically focus on where or when harvesters allocate their effort within a fishery, adjusting effort on the intensive margin in response to fishing conditions and management. However, many harvesters participate in multiple fisheries during a year, and thus a major consequence of management change is...
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...
Fishing is the most dangerous job in the United States. When fisheries management creates the incentive to "race for fish", a fishing season can be reduced to only a few days and involve around-the-clock fishing in life-threatening weather conditions. Overloaded vessels, ignoring maintenance problems on vessels, and fishing in dangerous...
In an open fishery, the competition for the limited fish stock can lead fishermen to a ``race for fish" with sub-optimally high capital investments. Buyback programs to reduce excess capacity in national fisheries have been often used, but seldom successful. Where they have successfully reduced excess capacity, the programs have...
Self-management has been recognized as important in successfully governing the common pool resources. This is no exception in fishery. Fishery cooperatives, where fishermen collectively manage the fishery, are garnering much attention from both regulators and academics. In this study, we aim to empirically disentangle the efficiency mechanism of pooling system....
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...
Pantar Island's coastal communities like many other coastal communities in eastern Indonesia have a high dependency on marine resources for income, food security and other benefits. Fish products (comprising several species of demersal and pelagic species) are particularly valuable (in addition to other products harvested and traded for export markets)...

Both internal and external factors influence on the market orientation of actors in the chain. In the case of the Norwegian king crab fishery the regulation of the fishery, i.e. the start of the quota year in September, was regarded by the onshore processing industry to negatively affect their market...
Worldwide there is a recognition that fishing communities face challenges in changing environments, changing markets, and under different types of stressors. In this context, it is important to identify the causal factors of vulnerability and to understand how people deal with them, in order to find ways to reduce the...
Illegal, Unreported and Unregulated (IUU) fishing is a pervasive practice in small scale fisheries. It affects the ecosystem and the livelihoods of people depended on the fisheries resources. Many times management technical measures from development partners and government have been implemented without success. In this study, we apply governability framework...
Over 11 % of total population engaged in fisheries and aquaculture and out of them about 10% is women in Bangladesh (DOF, 2013). Thus, women make essential contributions to local food security and in many cases; they take part in the commercially fishing production and trading too. There are pervasive...
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...

Many experts have argued that the traditional management of commercial fish stocks as single-species is short-sighted, wasteful, and ineffective. Ecosystem-based fisheries management (EBFM) now is being promoted as a potential solution to the problem. While much attention has been directed recently at the potential benefits of implementing EBFM for commercial...
If the spatial and temporal distribution of resources is not homogenous it creates an assignment problem. While the adoption of individual (or transferable) quota management in many commercial fisheries has resolved issues of over-appropriation, assignment problems may remain due to the spatial and temporal complexity of fisheries resources, which creates...
Context and objective: Beyond leisure and food (sea ES) → MRF boosts maritime economies, but not a formal industry in our economic accounts. EU DCF → increasing focus on MRF, to be considered in commercial fisheries management decisions (CFP). Limitations of traditional approaches (aggregated expenditures,non‐market microeconomics) to assess MRF economic...
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...
The paper devises an integrated ecological–economics–social model to assess the implementation of ecosystem-based fisheries management in the Pearl River Estuary (PRE) in the South China Sea (SCS). In particular, this paper presents the development of an integrated model, which links a regional economics social accounting matrix (SAM) model to an ecological...

Balancing the goals of economic development and sustaining ecosystem services remains a challenge for policymakers, particularly in the marine environment where ecosystem dynamics and human interactions are both complex and poorly understood. Implementing environmental management policies, such as environmental restoration, is a common response by policymakers where economic and environmental...
The purpose of this paper is not to present new game theoretic results, but is rather to discuss a new and much needed research program, which is at an early stage. Progress to date will be reported upon. It is the contention of the authors that, in stark contrast to...
Ecosystem services (ES) provide a pathway to connect ecosystem processes to human well-being. Ecosystem-based fisheries management can utilize the ecosystem service framework to assess trade-offs of actions such as restoration and gear restrictions, or environmental changes such as ocean acidification and warming, and sea level rise. However, due to a...

specifically examined the socio-economic characteristics of fresh fish marketers in the study
area, determined profitability and examined market structure for fresh fish in the study area .A
multi-stage sampling technique was used to select 45 fresh...
Throughout the world the landings of capture fisheries are declining and this is not because the fishing nations are managing their resources better but because of the non-availability of the fish species. The reduction in capture fisheries is a wakeup call for the nations to undertake Aquaculture development.
Though Namibia...
Fish farming has grown very rabidly during the past few decades. One component of this expansion is the introduction of new species, previously unknown to most consumers, to world markets. Arctic char, a cold water salmonid, is one of these species. In 1987, the total commercial supply only amounted to...
Almost all recent empirical literatures that study the subjective wellbeing of fishers lack of relevant control as they are only based on surveys among fishers. Therefore, they cannot really answer whether being a fisher generate higher or lower life satisfaction, after controlling for other aspects of life. This study is...
In the framework of the H2020 PrimeFish project, whose general objective is to contribute to enhance the economic competitiveness of European fisheries and aquaculture sectors, the analysis of innovation and new product development in the seafood market is an important issue. Simultaneously, concerns on the environmental impact of seafood industry...
This paper highlights the fishing industry's views on economic impact assessments related to fisheries, and in particular the Scottish Government's assessment accompanying the MPA Consultation. The industry felt this assessment was incomplete, failed to recognise the true impacts on fishermen affected and failed to acknowledge local impacts on communities. We...
Historically, cod fishing along the coast of northern Norway has been about fishing as much as possible with the least possible resource effort. This traditional logic is rooted in biology (cod’s migration pattern), meteorology (weather conditions) and traditional capture technology (small and not as seaworthy boats). The logic is further...
Despite the efforts of natural resource economists to implement rights-based fishery management systems, many of the world’s fisheries remain over-exploited and lack an institution to change course. Given the status quo of overharvesting and depleted fish stocks, it seems natural for a harvester co-op to jointly curtail fishing mortality, which...
Nigeria’s domestic supply of fishery products falls short of the demand; however, there is a growing aquaculture industry that has come to the rescue in filling the gap between supply and demand. Most of the aquaculture fish farmers are prone to the risk of climate change, since weather and extreme...
Capture fisheries can potentially provide a wide range of social benefits, many of which make important contributions to local livelihoods and national economies. However, in practice, and in many representations of fisheries, the starting point for assessment is the biological, fish, element of the system and its production potential. The benefits...
Bycatch of non-targeted species in marine fisheries has become a major policy issue in fisheries management over recent years. One approach to curbing the bycatch problem is the voluntary sharing of detailed spatiotemporal information between vessels as an aide in individual bycatch avoidance as well as a tool to lower...
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...
The main objective of this study is to assess seafood marketing and pathway in Nigerian coastline (the case of Lagos and Ondo States in the South West, Nigeria).

To examine the impact of the Landing Obligation (LO) on the Irish fishing industry and explore possible mitigation strategies, we carried out two trials on commercial fishing vessels in 2015. One vessel targeted Nephrops, the other mixed demersal whitefish in Irish waters. The study was in two phases. In month...
The main objective of this study was to describe the marine artisanal fishery in Tanzania mainland by manipulating data from frame and catch assessment surveys from 1984 -2011. Results showed that catches have been fairly stable while fishing effort has been increasing leading to decline in CPUE. This could be...
When a new market is created for ITQs, fishermen may have little information about the value of the newly-created assets that they hold. As such, concerns have been raised regarding distributional concerns associated with the transition to market-based management of natural resources. Aside from the first-order concerns regarding the initial...
The presentation discusses cost data collection methods and use in support of commercial fisheries management in the Pacific Islands Region, United States. Traditionally, economic information on Pacific Island fisheries was limited primarily to the dockside value of landed fish. Data on fishing expenses were obtained intermittently, through episodic surveys conducted...

Use of indigenous knowledge systems (IKS) is critically important in production systems and environmental management in Nigeria. Despite the importance of fisheries to Nigeria’s economy and the indispensable role of IKS in it, IKS used in fishing households have not been adequately researched. This study identified and examined the utilization...
Traditional approaches to halt decline of fisheries resources focus on regulating against destructive practices, but to little effect. A more effective strategy could be to establish a direct economic incentive mechanism such as payments or compensation schemes, or to incorporate such payments into existing regulatory mechanisms. Examples from terrestrial environments,...
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...
Key Takeaway: Understanding this process and factors that influence compliance decisions can help support the development of effective regulations. Importance of consistent observer coverage. Compliance varied by violation choice. Importance of port-level campaigns.
Main objective of this paper is to investigate current issues of the development of Culture-Based Fisheries (CBF) within the existing legal frame work.

In Bangladesh, women constitute about 50% of the population but comprise only one-fourth of the labor force. Considering women's critical roles in fisheries sector many projects in Bangladesh address both men and women as target groups putting more emphasis on women groups. One such project is "Emergency cyclone Recovery and...
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...
Future changes in Arctic marine ecosystems will depend as much on global climate change as on our ability to regulate and manage exploitation pressure at sustainable levels. There is a lack of integrated, cross-sectoral ecosystem-based analysis of the Arctic marine management. The analysis is on both the choices for implementing...
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...

are applied to the shrimp trawl fishery, which is a typical tropical fishery with the characteristic properties
of small...
Fishing systems provide employment, income generation, poverty alleviation, and food security. Management actions have ecological, economic and social implications that must be addressed carefully. The coexistence of small-scale fisheries (SSFs) and large-scale fisheries (LSFs) increases management complexity. Game-theoretical bioeconomic models empower management decisions in such complex systems.
The Philippines is surrounded with many fishing grounds. In spite of this, most fishermen in the area live in poverty, and their plight is getting worse, not better. Current fisheries policies for the area have failed to improve the situation but no research has been done to find out why....
South Pacific albacore is a species of primary importance in the longline fishery of a number of Small Island Developing States in the Western and Central Pacific Ocean. Despite the fact that the stock is assessed as not being subject to overfishing, nor overfished, economic returns have declined significantly over...
The presentation summarizes preliminary results of the first part in the PhD project “Economic valuation of the wild salmon stock in Norway”. The externalities from the salmon farming industry, such as spread of parasites and genetic pollution, affect wild salmon populations.
