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.
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...
In multi-species fisheries, technical and social interactions between different components of the fisheries can make it difficult to maximize economic yield. Furthermore, the different fish stocks contributing to the overall catch may present different levels of natural variability leading to difficulties in determining optimal management strategies. Bio-economic performances of multi-species...
Consumption of organic seafood is low in Europe. One reason may be low availability or high price. However, there seems to be confusion among consumers regarding what organic fish is, and how it differs from sustainable products. This may also contribute to the low consumption level. The objective of this...
The Atlantic salmon (Salmo salar) is a treasured catch for both commercial and recreational fishers at the Baltic Sea. Especially in Tornionjoki river, which is one of the two remaining wild salmon rivers at the Finnish coast of Baltic, recreational fishing is an increasingly popular activity, and a source of...
Many fishermen diversify their income by fishing in more than one fishery which can significantly reduce year-to-year variation in income. However, opportunities to diversify have become more limited as access to fisheries has become more restricted. The implementation of catch share systems could further reduce diversification if those who remain...
In front of new evolutions of purchasing behaviors, the seafood marketing has to adapt itself by integrating more services into products, a better dramatization, an recourse to new advertising and promotional instruments … The supply not only has to adapt itself to the situational constraints of shoppers, but rethink its...
Impact assessments (IA) are a requirement for all new European Union regulations. A central part is the analysis of social and economic impacts. For fisheries regulation the European Commission is responsible to provide the IA to a board within the EC. They are not doing the analytical assessments and data...
This paper analyzes the equity consequences of different fishing quota distributions among artisanal fisher organizations. We develop a basic model to analyze optimal decisions with a collective fishing rights system. With this model as a conceptual framework, using a Theil index as a distributive measure, and employing optimization techniques we...
The value chain for the sea cucumber fishing industry in Sri Lanka was analyzed using the data collected by interviewing the main actors of the chain from February to December 2014. Divers, buyers, processors and exporters are the main actors in the value chain. Divers are the key upstream players...
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...
Lake Nasser extends for more than 300 km inside Egypt`s border and has an extensive shoreline of around 7000 km. It is an important source of fish for residents of Aswan and adjacent governorates in Upper Egypt, representing 55% of the total production from inland lakes in Egypt in 2013....
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...
Optimal management of herring, mackerel, and blue whiting in the North East Atlantic is analyzed. The main motivation is to quantify the potential gain from implementing multi-species management compared to traditional single-species management. The objective is to maximize discounted net revenue; in other words a sole-owner perspective. The results are...
Fish products are among the most highly-traded commodities. The proportion of fish harvests that is internationally traded has steadily risen over time. As a result, trade has become a key driver of the dynamics of local fisheries, with a range of ecological, economic and social impacts. This paper reports empirical...
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...
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...
As the demand for sustainably caught seafood increases, market actors are increasingly interested in engaging with initiatives to increase the sustainability of their supply chains. Fishery Improvement Projects (FIPs) have been implemented in many parts of the world and are a way by which retailers and their 1st and 2nd...
This study examines price formation of the internationally traded salmon futures exchange. The results show that the futures market price provides the expected role of leading the spot market price. Further, the futures market is efficient but hindered by the presence of risk premium that biases the forecast ability. The...

The approach analyzes the effects at the individual vessel level through representative surveys of costs and earnings data. Bioeconomic theory and a vessel economics framework for an open-access fishery...
This study proposes three methods for technical efficiency (TE) estimation using three different fish stock proxy measures while applying the stochastic production frontier (SPF) approach. We apply these methods to two Vietnamese offshore fisheries, gillnet and hand-line, for which measures of stock abundance are unavailable. Based on the assumption of...
After half a century of fisheries development focused on large-scale fisheries the policy arena is finally becoming more conductive to sustaining small-scale fisheries (SSF) in economically developing countries, with a particular focus on international trade opportunities. Debates for and against increased integration of SSF into globalized trade have been presented,...
Excess capacity and overfishing have constituted major threats to sustainable management of fish stocks. Moreover, if capital is locked in unproductive capital in fishing vessels it also constitute a threat to social welfare if fish abundancy and prices are too low to support the livelihood of fish dependent communities and...

We make use of unique data that allows us to follow complete production cycles for a sample...
The availability of economic performance data at farm level is a necessary precondition for basic economic analysis of aquaculture production systems. However reliable and comparable data are often missing. Due to different production systems with varying economic performances, a quantitative data collection is quite complex and expensive. The Thünen Institute...
This study attempts to design MPAs to manage sea cucumbers in the coastal waters of Sri Lanka. A bio-economic model developed by Stefansson and Rosenberg (2005) was used in this study. In model simulation, area between 080170 - 060 500 N and 810 250 - 820 was considered and this...
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...
Accurate cost estimation is crucial in fisheries economic analyses, but is often the least known component of many studies. For the past two decades, a systematic approach to collecting fishing cost data has been employed by the Northeast Fisheries Science Center through the sea sampling program, i.e., onboard observers collecting...
One way to evaluate the bio-economic performance of fisheries is to base the decision to harvest on whether there is a benefit from leaving particular sizes of fish to reproduce or sell them today at market price. This takes into account both size-dependent fecundity and size-dependent pricing, two commonly overlooked...
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...

The effects of selected variables on margins were examined for two marketing agents - spouse and other agents. A system of equations were estimated separately for the major and...
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...
Aquaculture has been the world's fastest growing food production technology in recent decades and the effects of its developments are felt in seafood markets worldwide. As a result, fishermen face an additional challenge that has the potential to impact their choice of whether to reduce participation, what species to target,...
Achieving the optimal designation of marine protected areas (MPAs) and design of management measures requires a comprehensive understanding of potential socioeconomic impacts. Yet, assessing the impacts of MPAs and how they are distributed faces significant data and other evidence constraints. What role can monitoring and adaptive approaches play in MPA policy...
When the South Atlantic Fishery Management Council (SAFMC) determined the black sea bass (BSB) stock was rebuilt, the annual catch limit (ACL) more than doubled. A segment of the commercial fishery had historically used fish pots to catch BSB and prior to the increase in the ACL, the fishery was...
While studies have long examined the economic viability of oyster industries along the Pacific and Atlantic coasts of the mainland United States, Hawai`i has had no industry to speak of in decades. The Pacific oyster, <i>Crassostrea gigas</i>, is being cultivated in a traditional Hawaiian fishpond for the first time, providing...
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...
We describe the dynamics by which competing harvesters selectively target prime market-sized fish, without internalizing the externality of increasing targeting costs, as the abundance of prime fish decreases. Due to the increasing targeting costs for prime size, harvesters continually target the next-most-desirable size fish, gradually fishing down the size structure...
While the literature that uses economic experiments to investigate self-governance of common pool resources is large, almost none of it is concerned with protecting resources from outside incursion. This work presents the results of an economic field experiment designed to study behavioral issues related to both the protection of a...

Balancing sustainable utilisation goals and equity in socio-economic outcomes become challenging in managing artisanal fisheries, confronted by fluctuating fisheries-resources and poor management-structures. Such artisanal trap-net fishery called "Paddi-Valai" has been targeting shrimps in Anthoniyaarpuram coast in northern Sri Lanka. But its main by-catch, blue swimming crab (BSC), Portunus pelagicus, has...
Subsidies are most often discussed within global fora (such as the World Trade Organization) in terms of concerns over trade distortions, if some countries gain an unfair advantage, through their subsidies, over unsubsidized industry elsewhere. In fisheries, this concern is matched by an environmental argument – that fish stock depletion...
This presentation explores the interaction of the fishery sector and the emerging push for marine biodiversity conservation. These are viewed as two ‘streams’ of governance – flowing through global bodies (notably the United Nations), through nations (with interacting environmental and fisheries agencies), and through thousands of coastal communities worldwide (which...

To effectively respond to sustainability challenges, there is a need to find (or re-discover) suitable ways to govern, so as to make decisions that maintain healthy environments and sustainable livelihoods in fishery systems. While efforts to this end are needed at all governance levels, from the global to the local,...
Marine protected areas (MPAs) have become a widely used tool for marine conservation and fisheries management. In coastal areas, it has become clear that the success of MPAs, and the achievement of sustainable fishery production, requires a combination of effective management and conservation frameworks, maintenance of decent fisheries livelihoods, and...
There is increasing recognition that the oceans of the world support a wide range of economic sectors. Managing those multiple uses, within a ‘commons’ environment, is undoubtedly challenging. Approaches of ecosystem-based management (EBM), integrated ocean management (IOM) and marine spatial planning (MSP), with associated aspects of spatial allocation and conflict...
Retailers and suppliers of seafood are concerned about assured supply and their broader reputation with consumers. In theory, these concerns align with efforts to manage fisheries sustainably and reduce their environmental and social impacts. Hence engaging seafood supply chains more actively in fisheries management should help improve the fisheries in...
The debate in commercial fishery management has evolved from whether well-defined rights are necessary for sustainability to evaluating the advantages and disadvantages of different rights based system designs. Two of Latin America's largest fisheries, the Chilean Jack Mackerel and Peruvian Anchovy, allocate quota at the vessel-level and restrict the lease...
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,...
The goal of this research is to analyse the employment trajectories of more than 1300 fishermen in the French region of Pays de la Loire (Atlantic coast). The dynamic analysis of careers in the fishing sector is of importance to predict the future of this sector. Indeed, the flexibility of...
