Scallop fishing was in effect a regulated open acceess fishery in UK until 2012 when the Western Waters management regime was implemented, limiting the maximum effort for the UK fleet of over 15m vessels and, via the UK government, limiting effort per vessel over 15m. This analysis identifies the main...
Joint production of multiple offsets and/or ecosystem services that enter in multiple markets complicates the standard interpretations of baselines, additionality, and the process of stacking. Intuitively, joint production means that the process of providing the multiple offsets and/or ecosystem services is interrelated, and nonjointness means that each offset or ecosystem...
Women in general play a critical role in every aspect of the production process and value chain in small-scale fisheries. Their best known roles are however in processing and marketing of fish and fishery products. The fish sector (capture fisheries and aquaculture) is an important source of income and livelihoods...
Unilateral conservation of a transboundary resources, notably bycatch species, can lead to production, trade, and conservation leakages, losses in net benefits to society, and, paradoxically, increased rather than the intended decline biodiversity loss. A 2001 time-area closure of a key fishing area for the California-Oregon drift gillnet fleet harvesting swordfish...
The H2020 SUCCESS project aims at improving the competitiveness and economic sustainability of the European seafood sector. In accordance with the Call (BG-10-2014), SUCCESS will in particular identify "success stories", defined as innovative or alternative ways of running aquaculture and fisheries businesses. These exemplary cases will be reported during 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.
There are perennial efforts in forecasting future fish supply and demand (e.g. the IFPRI Fish to 2020 model, the OECD-FAO Fish Model and the WB-IFPRI-FAO Fish to 2030 model). A panel model is developed to estimate a country's fish demand in the future. Instead of using a country's' own historical...
This study compares and extends existing approaches to predict the location of fishing activities. Using data from Northeast U.S. Fisheries, we show that the traditional spatial representation of fishing activities leads to a severe misrepresentation of fishing grounds and effort. Predictions based on probability models outperform most of the simplified...

A general discard ban is currently being introduced within the Common Fisheries Policy of the European Union. The gradual implementation of this landing obligation (LO) started in the beginning of 2015 and is to apply to all fisheries within the EU by the beginning of year 2019. A major challenge...
The Fisheries Research Agency launched the grand design of fishery resource management in Japan in 2009. In the grand design, 16 roles of fishery industry in Japan were categorized into five aspects including: (1) resource and environmental policy, (2) food policy, (3) industrial and economic policy, (4) local and community...
Spatial closures are a prominent tool for ecosystem-based management in commercial fisheries. The potential benefits of spatial closures in commercial fisheries have been discussed thoroughly in the literature; however, empirical estimates of the potential short-run costs incurred by the commercial fishing industry are relatively scarce. Spatial closures constrain the ability...
The generation of market information is critical in the dynamic and highly differentiated global seafood market. Information has strategic value and market information is therefore vital in creating and delivering value. However, the context of long, globalised supply chains and highly differentiated seafood markets results in value chain members having...
Climate change is expected to influence the spatial and temporal distribution of fish stocks. The aim of this paper is to compare climate change impact on a fishery with the impact of other factors on the performance of the fishing fleet. The fishery in question is the Northeast Arctic cod...
Background: Many studies have suggested that fisheries management may affect fishing safety. However, there has been relatively little systematic analysis of how fisheries management affects safety or the extent to which changes in management can make fishing safer or less safe.
Methods: The Food and Agriculture Organization of the United...
The hilsa shad (Tenualosa ilisha) fishery is the largest single species fishery of Bangladesh managed under open access system was chosen for the study. The purpose of the study was to develop optimal policy to assess the optimal exploitation of the fishery. The objective was to maximize the net benefit...
In 2011, NOAA Fisheries implemented catch shares in the US west coast groundfish trawl fishery to benefit both fish and fishermen. Once these catch shares could be traded, well-capitalized organizations such as processors had an advantage over individual operators in that they could act quickly when shares become available on...

Payments for Ecosystem Services (PES) is a relatively new tool for fisheries and aquaculture. Being part of the broader incentive- or market-based incentives, PES is a positive and voluntary incentive mechanism that compensates actors for increasing or maintaining the provision of ecosystem services. Our investigation considers potential and actual PES...
The Leptobotia curta, known as the Ayumodoki in Japanese, is a Japanese endemic freshwater fish that has been designated as a national treasure since 1977. This fish is, however, categorized as a "critically endangered species" by the Ministry of the Environment's Red Data Book in Japan. While a direct reason...
Fishing is risky business. Managers and Fishermen therefore care not only about the average income, but also about its variation. In spite of its importance, little is known about the observed risk exposure of fishing firms and its determinants. We have obtained complete landing tickets data for a significant share...
Choices are often limited as the most popular alternatives reach capacity and sell out; thereafter, selection is over less preferred choices. In the context of nonmarket goods, willingness to pay (WTP) welfare measures provide an estimate of the value of characteristics – often calculated through the modeling of preferences using...

Kappaphycus alvarezii is economically-important seaweed due to higher carrageenin contents. Suitable culture-method, culture-sites and solutions for fish-grazing have not been tested. Hence, growth-rate ofK.alvarezii under three culture-methods namely raft, line, and cylinder-cage were compared off Velanai and Kayts, in northern Sri Lanka from April-August 2014. Raft and line culture-methods were...
Calls to account for ecological interactions and tradeoffs in fishery management have grown over time. For example, some groups are asking to reduce global forage fish catch by 10-20% to ensure food supplies for other species These efforts follow advances in ecology and the development of large food web models,...

Fisheries managers are increasingly expected to manage fisheries in an “ecosystem-based” manner – accounting for ecological interdependencies across species and their coupling with the physical environment. Yet managers lack rigorous, bioeconomic EBM indicators to assess tradeoffs and measure whether the natural capital in exploited ecosystems is sustainably managed. We build...
Excess and over capacity are key management issues in global fisheries. These issues have also received widespread attention in the literature. Previous work on firm-level investment behavior in fisheries, both theoretical and empirical, typically assumes risk neutral and profit maximizing agents. While this work has led to a much better...
This paper traces the rise and fall of, in its day, one of the most important fisheries in the world. The fishery exhibits the impact of changes in demand and supply brought about by technological advance in three noticeable shocks. Fishing is said to have commenced in 495AD. So prolific...
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...

A two-species bioeconomic model is analyzed, but in contrast to most similar models, there is no biological interaction between the species, only economic. The interaction takes place in the market where the quantity of either species may affect the price of the other. Both the sole-owner and the open access...
The way of individual (fishing) quota is now widely recognized as a useful way for fishing resource management. However, even in the (internationally) shared resources, distributions of non-transferable fishing quota for each country should be justified, shouldn't be? The research considers the logistics "to begin with" in the theoretical international...
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...

Over the past several years we have been developing Fishery Performance Indicators (FPIs) to measure the degree of success fisheries systems have in achieving environmental, economic and community outcomes. We have also developed indicators of key input factors. Among the input factors we have explicitly developed indicators for women’s participation and leadership...
The Dungeness crab (Cancer magister) fishery is one of the most valuable single species fishery in Oregon, with an average annual ex-vessel value of $45 million from 2004-2014. The fishery is managed using a "3-S" (minimum retention size, male retention only, season length) management paradigm. In addition, fleet capacity has...
While the discussion of the use of rights based management for recreational fisheries began over 10 years ago, there are still very few examples of recreational fisheries managed under a rights based approach. Recreational users in the US have been extremely resistant to strong forms of rights based management for...

A part of the project deals with the understanding of the consumption patterns in different European countries. Knowing that TV and other media programmes can have an impact on consumption choices, this paper...
Bioeconomic modeling of an age-structured population typically assumes the value of a fish increases with size; the fish increase in weight as they age, and harvesters may receive an increase in the price per weight. When size selectivity is possible, traditional policy such as individual quotas may still result in...
Economics and political decision making are concerned with allocation of scarce resources among competing ends. Different decisions generally have implications for economic production and distribution, society and stakeholders, and environmental systems and ecosystem services. Stakeholders often seek to influence decision processes using economic arguments about the relative values of different...

The research first considers the unique characteristics of SIDS and the continuing difficulties and challenges of traditional methods of capture fisheries management. The key...
Buyback auctions are often proposed as a policy to reduce excess capacity in fishing fleets prior to or in place of implementing a tradable quota program. In this paper I take a critical look at possible designs for such a policy in environments with uncertainty and asymmetric information. In an...
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...
