Salmon aquaculture is constrained by the proliferation of salmon lice, a natural seawater parasite that benefits from the agglomeration of production. The lice challenge currently costs the Norwegian salmon farming industry above 450 million USD per year (0.5 USD/kilo). Adjacent farms impose a contamination externality on each other, which they...
The world's fisheries are a critical piece of the world's food supply, providing an important source of protein for billions of people and employing millions in the process. From a human perspective, it is important that fish stocks around the globe be managed in ways that can continue to provide...
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...
In this study, socio-economic structure of fishermen in Samsun Shelf Area was investigated between January 2014 and May 2015. Questionnaires were applied to 42 fishermen by visiting the region three times. At the end of the study, the age distribution of the fishermen were mentioned between 29 and 69 years;...
Annual socio-economic surveys, pared with third-party landing monitoring data, have allowed a multi-year analysis of the economic impacts and perceptions of implementing an individual vessel quota rights-based management system in the gulf corvina (Cynoscion othonopterus) fishery. This fishery is targeted by four communities, including an indigenous one, in the Upper...

The presentation was part of Session A1: Market Challenges: Ethics and Social Responsibility. The session was chaired by Dr. Tom Pickerell, and the presentation was given...
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...
Notwithstanding the increasing use of area and seasonal closures to promote the sustainable use of coral reef fisheries, few studies have examined the socio-economic performance of these management strategies. This study describes small-scale fishermen's views regarding the biological and socioeconomic performance of these management tools off Puerto Rico. Our findings,...
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...
In Tanzania, the overall objective of the National Fisheries Policy is to develop a robust, competitive and efficient fisheries sector that contributes to food security, nutrition, growth of the national economy and improvement of the wellbeing of fisheries stakeholders. The overall goal of fisheries management is to produce sustainable biological,...
The UN Voluntary Guidelines for Securing Small-scale Fisheries, along with the Voluntary Guidelines for Responsible Governance of Tenure of Land, Fisheries, and Forests, recognize the role of secure tenure in ensuring the livelihoods, well-being, and basic human rights of small-scale fishing (SSF) communities. Rights-based management (RBM), which works to secure...
This presentation provides an overview of a Special Session presentation held at the NAAFE Forum 2017 in March, 2017. The title of the special session was: Saving the World's Most Endangered Marine Mammal. The session was organized by Oriana Poindexter.
Poverty issues cannot be underestimated in fish farmers' production as they influence farmers' attitudes towards risk. Despite the fact that there are studies on fish production risks, there is little or no study on fish farmers' poverty status and risk attitudes nexus in Nigeria. Hence, this study examined risk attitudes...
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...
Commercial fisheries rationalization has promoted economic benefits and accountability to annual catch limits, but most recreational fisheries are managed under regulated open access with relatively poor catch accounting, short and unpredictable seasons, and persistent overharvests. For many mixed-used fish species, recreational fishing represents over half of total fishing mortality. Yet...
Recreational fishing in the Gulf of Mexico has followed a familiar pattern to that observed in many commercial fisheries: fishing under regulated open access has promoted a “race to the fish” with cascades of shorter seasons, shrinking bag limits, and significant discards. These restrictions may have significant effects on angler...
The paper explores the characteristics of fishing industry and multi-goals pursued through the legal regimes and policies on Chinese fishing industry, and analyses some problems with the existing legal regimes on fishing.It is concluded:
(1) that fishing licensing system needs to be reformed under the theories of property law and...

For decades, fishing was considered an area warranting public support policies, particularly its industrial segment. The sector continues to enjoy the support of international donors in addition to significant private overinvestment. Globally, catches of artisanal fisheries continue to grow while industrial fisheries decline since the mid 1990s. The latter are...
Fisheries subsidies have been roughly estimated to be as high as $35 billion worldwide, of which about $20 billion have been categorized as capacity-enhancing subsidies that directly contribute to overfishing. Since 2001, the necessity for reforming fishing subsidies has been part of the discussions in the World Trade Organization (WTO)....
Management objectives of vulnerable fish species must focus on maintaining healthy population status. Hence, reference points should be constrained to ensure recruitment. We assessed bioeconomic reference points for the totoaba (Totoaba macdonaldi), an endemic fish to the Gulf of California, reaching lengths of 2 m and 25 years. Totoaba fishing...
Fisheries are recognised to provide important contributions to the economy, through the creation of jobs, growth and GVA from both the catching sector and associated supply chain activities. They also provide social benefits, through individual well-being, contributions to strong communities, and knock-on benefits through supply chains. However, in national terms...
Scholars of natural resource systems increasingly refer to ‘governance’ as a crucial steering activity for sustainable management of natural resources. It is now common practice to speak of ‘ocean governance’, ‘coastal governance’, and ‘fisheries governance’. Within governance, sustainability and decentralization are two major factors that underpin the success of governance...
Catch share management programs are designed to reduce overcapacity in fisheries through trading as efficient harvesters buy out their less efficient counterparts. Numerous studies have looked at either the ex-ante potential of catch shares management to reduce overcapacity in a fishery or the ex-post effects of implementing such a program,...
We suggest freshness as a critical factor in determining fishing trip duration. Using daily logbook data from a Japanese-based longline fishery, we find that prices are highly elastic with respect to the freshness of the product, with a 1% decrease in our freshness measure corresponding with a 3.85% decrease in...
An international conflict between pro- and anti-whaling countries has been a concern. While many Western countries condemn whaling, Japan conducts ‘research whaling’ under the special permission of the International Whaling Commission (IWC) along with Norway and Iceland, who also engage in commercial whaling. Especially Japan and Australia have been divided...
This presentation provides an overview of a presentation held during the Industry and Policy Day held at the IIFET 2016 Scotland conference in July 2016. The presentation was part of Session B3: Adapt, Improvise and Overcome - fishermen's responses to the LO. The session was chaired by Dr. Erik Lindebo...
In fisheries, as well as in other natural resource based industries, there is a difference between the concepts of profit and rent. The former is a basic indicator for gauging the business performance of firms and industries, and the latter is for the evaluation of the economic welfare contribution of...
Pangas is a relatively new and fast growing fish species, which has shown great potential in the Bangladesh aquaculture sector. However, large output variability is observed from farm to farm and from different locations, which may indicate that production risk and inefficiency is a problem in pangas farming. This study...
In the Pacific Northwest of the United States, hundreds of millions of dollars are spent annually to restore upland stream habitat for salmon populations listed under the Endangered Species Act (ESA). Despite this sizable financial commitment to salmon population recovery, in practice, the restoration projects selected for implementation are often...
As part of PrimeFish project, the competitiveness of European fisheries and aquaculture will be analysed by examining the supply chain relations and regulation of selected value chains of five commoditised fish species within the EU: Atlantic salmon, rainbow trout, cod, herring, sea bass and sea bream; as well as imported...
The main objective of the PrimeFish project is to consolidate and improve the economic sustainability of European fisheries and aquaculture sectors. The achievement of this goal implies a good understanding of how the seafood market is impacted by the consumer behavior and how trends in product innovation evolve. PrimeFish works...
Two thirds of seafood consumed in EU is imported. The EU capture fisheries sector has been stable during the last few years but EU aquaculture has declined. The EU capture fish industry has its main challenges related to the supply of fish because of overfished stocks and extreme seasonality of...
This study was conducted with the aim of modeling and forecasting the Indian shrimp export prices to the USA. Two major species mainly Black tiger (Penaeus monodon), white legged shrimp (Litopenaeus Vannmei) headless, shell on form, grade 16/20 were considered for the study. Published data on weekly price indicators of...
Seabream is the most important farmed species in the Mediterranean region, and Spain is the largest market. A key question for this industry is to assess the way in which negotiation power is distributed along the value chain. Price transmission is studied by analyzing market integration between different levels of...
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...
Price formation of fish in landing market was studied in Japan to examine price discounts of fish species regularly landed in small quantity. It is often told that buyers tend to offer low bidding prices for fish which have small landing amount in a day because handling and shipping costs...
The effects of regulations on recreational fishers are especially difficult to predict. Data lags typically prevent in-season management, so regulations restrict aspects of individual fishing activity in the hopes of achieving collective catch limits. This study began with discrete choice surveys to elicit angler preferences among various types of fishing...
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...
Depleted fish stocks and habitat degradation associated with human activity, particularly fishing, are both the subject of increasing concern and research. Harvest control rules and no-take marine reserves are two management approaches regularly advocated as effective means of restoring depleted fish stocks and preventing fishery collapse. We incorporate these two...

The Gulf of Mexico Red Snapper IFQ Program (Program) was the first catch share management program implemented in the Gulf of Mexico. IFQ management was implemented to reduce overcapacity and eliminate the problems associated with derby style fishing. The Program was successful, the number of vessels harvesting red snapper decreased...
We develop a theoretical model to address the effects of different market structures on the ex-vessel prices and consequently how this would impact the risk-sharing mechanism for harvesters and processors in fisheries. We focus our research on two market structures, price-at-landing (PL) and post-season pricing (PS). PL market structure is...
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...
The most known Lake Victoria dagaa fishery (Rastrioneobola argentae) in Eastern and Southern countries of Sub-Saharan African region consists characterized by physical, quality and economical (PQE) losses along the supply chain. The survey was done on the PQE losses on Sun dried dagaa along the supply chain. Losses are at...
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...
The seafood sector has been followed and presented through different data collected as for example by FAO over several years. Often these studies are globally and/or macro-oriented market and even though these studies clearly add insight and understanding they do not provide the details needed for assessing the different sectors...
