Aquaculture has been identified term in the European Union Blue Growth strategy as an activity with high growth potential in the long term. The supply and demand of farmed salmon have been steadily growing in the EU. However, most of the salmon is imported to EU from Norway, while the...
A marine protected area (MPA) is a management tool used for biodiversity conservation and sustainable fisheries development, but it is less used for non-extractive uses of ecosystems such as eco-tourism. We estimate the willingness-to-pay for improved environmental qualities of the Nha Trang Bay MPA on one hand and employment effects...
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...
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...
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...
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,...
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...

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...
This paper explores, using an historical example, the challenges that small island economies face when they are heavily invested in one or two productive sectors, and where they have had privileged historical access to the resources that underpin those sectors, and suddenly that access is removed or reduced. The Islands...
Beam trawling on brown shrimp (Crangon crangon) is one of the most important fisheries for the German fleet. It is an open fishery without a defined quota. Indicators such as increased by-catch, a predominance of undersized shrimp in catches, and a high fishing mortality all suggest that improved gear selectivity...

Economic assessment data in agricultural systems at farm level require a substantial methodology in order to assure result reliability. This paper aims to evaluate the effectiveness of a participatory approach which is being used by the Brazilian Agricultural Research Corporation (Embrapa) in aquaculture. This methodology consists in gathering technical parameters,...
A necessary condition for successful management of fisheries is that fishermen follow the rules and regulations put in place. A survey was designed to ask anglers about their attitudes towards various recreational fishing rules and regulations, as well as to what extent the different regulations were complied with. Moreover, we...
In this paper an unregulated, but not open-access, fishery is studied and it is analyzed how more modern fishing technology may be a mixed blessing not only for the fish abundance, but also for the rent. The model is formulated in section two where it is included a strategic interaction...
The Spanish market for salted cod has undergone important transformations in recent decades. The collapse of the Newfoundland fishery dramatically reduced local processors’ access to the raw material, which previously was mainly supplied by Spanish vessels. The price of salted cod increased and processors margins decreased. By using price integration...

Nigeria....
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...
Live seafood is becoming increasingly popular in global markets. Seafood is one of the most important industries in Norway, and live crustacea is an increasingly important international marketing channel. King crab pioneered this trend in crustacea, now followed by emergent supplies of snow crab. As a new species, for Norway,...
Climate change and continued fishing pressure threaten to increase recruitment variability for many wild stocks. Additionally, as many seafood markets are now integrated nationally and globally, individual fisheries may be less insulated from broad macroeconomic shocks. Large inter-annual shifts in fisheries production may have dramatic consequences for economically dependent industries...
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...
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...
The demand for fish and fish products is on the rise and being sought as a preferred alternative to other animal protein, owing to its taste, preference and proven health benefits. However the consumers’ urge in knowing the fish origin and its quality are decisive factors for determining its saleability....
The Gulf of Alaska and Bering Sea pollock fisheries in the U.S. were certified by the Marine Stewardship Council (MSC) in February 2005, yet to date little other than anecdotal evidence exists to suggest whether products from these fisheries have gained market benefits relative to uncertified pollock from, for example,...
In every US fishery where value has been examined, recreational value far exceeds commercial value in aggregate and at the margin. For these same fisheries, recreational economic activity almost always exceeds commercial economic activity even when the entire commercial supply chain to the consumer is included. However, even with extensive...
The value of commercial fisheries is expressed in a variety of ways in marine policy development, implementation and in individual marine proposals and consent decisions. This presentation provides a fishing industry perspective on the experiences of the delivery of Marine Protected Area and marine planning policy and licensing in the...
The experimental determination of the impact of small pelagic purse seine fishing on the iconic African penguin was initiated by the South African Department of Agriculture, Forestry and Fisheries in 2008. This has involved the plurennial closure of a 20 km radius area around four penguin breeding islands, alternating pairs...
A great number of public/private founded researches have analyzed the causal relationship among different potential drivers for prices, such as demand and supply growth, changes in prices of raw materials and other inputs as well as the policy about stocking. Some analysts suggest that recent price developments are mainly explicable...
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...
Brazilian aquaculture is undergoing major transformations which have been changing the whole structure of this sector.

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,...
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...
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,...
Individual Transferable catch-Quotas (ITQs) have become a popular management tool to reduce excess competition and foster economic efficiency in marine commercial fisheries. They have increasingly been used in more complex multispecies fisheries, where the by-catch of non-targeted species is common. In these fisheries, the reduction of discards is also being...
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...
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...
Geographers and regional scientists have long recognized that "near things are more related than distant things." Ports located far from each other may compete through use of the same fishing grounds. We describe trends in competition in the Northeast U.S Sea Scallop Fishery using a Czekanowski Index over the past...
