Fisher behavior can be divided into choices made in the short term (i.e. tactics) and choices made in the long-mid term (i.e. strategies). Random utility modeling (RUM) is well suited for the empirical analysis of these issues. In this paper, RUM is applied to a number of EU fisheries in...
This paper deals with the economic impact of an aquatic invasive alien species on a coastal shellfish
fishery. A slipper-limpet (Crepidula fornicata ) was accidentally imported some decades ago, has
established and is spreading in the bay of Saint-Brieuc (France). This exotic species is acting as a space
competitor for...
In multispecies fisheries managed with individual fishery quotas (IFQs), fishers targeting certain species often have
insufficient quota to cover other jointly caught species. New Zealand employs a unique dual price-quantity system to
address this problem. In lieu of acquiring quota, fishers can opt to pay a fee per unit of...
Recent increases in imports of catfish and crawfish have caused concern as to their impact on domestic
prices. This study identifies the linkages between imports of these goods and U.S. producer prices.
Increases in imports of catfish are shown to decrease related domestic prices. However, recent trends
show a simultaneous...
Seafood consumption has been traditionally very important in Spain (about 36.5 kg per capita
consumed in 2003). Hake (merluza) is the main fish species consumed in quantity and value
terms in Spain. But commercialised as hake can be found several fish species and presentations.
When many papers focus on product...
Recent work in the domain of fisheries ecology has shown that major changes are occurring in fish
communities exploited by commercial fisheries. Selective fishing pressure on more highly valued
components of fish communities, and its indirect effects via trophic interactions, are amongst the key
factors proposed to explain these changes....
This paper re-examines the evidence of causality and price transmission between fish prices of main species landed into Piraeus (Greece) and Cornwall (UK). To complete the analysis of cointegration and causality, we use the data of Floros and Failler (2004) and Avdelas (2004). Our paper uses the Bivariate Generalised Autoregressive...
This paper explores the reasons why the ties between harvesting and processing have been severed in the
Icelandic fisheries in recent decades, and traces the role played by better transport, the emergence of
domestic wet-fish markets, and the introduction of freezing trawlers, as well as other factors in this
development....
Finnish fish markets have traditionally been supplied by domestic wild fish species: Baltic herring, salmon and several freshwater species. Nowadays, farmed salmon and rainbow trout dominate the market and wild-caught species are moving to niche product segment. In this paper we examine the market integration of Finnish fish markets. We...
One of the major sectors of Bangladesh agriculture is represented by the fisheries sector. Being a deltaic land
with numerous rivers and inland haors and beels (lakes and lowland areas of considerable size), and also ponds
that are dug in populated areas for the purpose of bathing, washing and often...
Tuna, after shrimps, forms the most valuable seafood product in both export and domestic market in Sri Lanka. The
first section of this paper discusses the present status of tuna industry in Sri Lanka and the behavior of export
markets. Secondly, this paper analyzes the impact of technological innovation, effort...
The direct economic values of aquatic resources used in various livelihood activities by
households in selected rural villages of Cambodia were estimated using the net economic value
approach. Data utilized were from 540 aquatic resources dependent households from 3 provinces
gathered using household survey, longitudinal monitoring and participatory rural appraisal...
Unfortunately, most of the stocks are damaged by natural disasters or human activities and rebuilding the
stock are urgent requirements. Until now, in the stock management, some policies are commonly believed
to valid but have not been confirmed. A simulation model of the population dynamics incorporating
uncertainty has been already...
This paper provides a Total Allowable Catch (TAC) assessment model for a single gear, multi-species fishery in South Korea. To estimate appropriate Allowable Biological Catch (ABC) of mackerel and jack mackerel caught by the large purse seine fleet in the territorial waters of South Korea, the model uses an extended...
The objective of the paper is to briefly present a comparative analysis of trends in the characteristics of
selected European fleets, observed over the last fifteen years, as an introduction to three empirical studies
of the behavioural determinants of these trends. The analysis presented aims at (i) describing changes
observed...
Three case studies were included in a study on fishing vessels, most of which use trawl gear in demersal
fisheries. The case studies include the French Bay of Biscay bottom-trawlers, the English beam trawlers
fishing in the English Channel, Celtic Sea and North Sea, and the Basque trawlers fishing in...
This paper discusses sustainable development of Yemeni fisheries towards achievement of Millennium Development Goals (MDG) and stakeholder aspiration. Yemen is considered a Least Developed Country ranking 148 among 174 countries in terms of the Human Development Index. In terms of food security, Yemen is classified as a Low-Income and Food...
France is Europe's largest market for salmon, close to saturation for traditional products but open to opportunities for differentiated items. Over the last ten years, the supply of salmon-based products has moved from basic items to more sophisticated ones. Processing is one way of turning the product into what consumers...
Globalisation continues to impact the fisheries sector, aided by international governance frameworks in fisheries production and trade. Within these frameworks, tensions exist between trade facilitating measures and trade restricting measures. For example, UNCLOS extended Exclusive Economic Zones to 200 miles, resulting in a significant increase in volume and trade in...
Although European fish consumption is increasingly dependant on aquaculture products given the
decrease of worldwide fisheries landings, the image of farmed fish is more and more controversial. This
paper aims at assessing the importance of farmed fish in the European seafood consumption, as well in
terms of image and perception...
The experiences on reproductive management of native specie such as Petenia splendida (Tenhuayaca) in the last four years in Tabasco, Mexico has generated enough information to allow the development of a technological package for supporting sustainable rural production, particularly in areas where most of the population belongs to ethnical groups....
Global aquaculture production increased with an average rate of 10% per year since 1990 and 90% of
aquaculture production comes from developing countries thus providing livelihood and income especially
to marginal groups who have limited access to resources such as agricultural land and financial capital.
Geographical information systems (GIS) based...
Whatever the quantity and the rate of water utilization is, economic principles indicate that there will
always be other water utilization methods which might increase the efficiency of the use of this resource.
Due to the geo-climatic position of Iran, this country finds itself in a water deficit situation as...
A community based sea urchin (Tripneustes gratilla) culture was chosen as an alternative livelihood by
fisherfolks of Nalvo, a fishing village along the South China Sea in Sta. Maria, Ilocos Sur, Philippines.
The sea urchin culture was adopted among fishermen to augment their rapidly declining income from
fishing. The said...
Shrimp farming in Iran is one of the fast growing segments of the economy. In 1994, around 1%
of Iranian shrimp production was farmed and by 2003 the share of shrimp farming increased to
60%. In spite of the fact that shrimp culture had relatively rapid growth in last decade,...
Wholesale demand systems for live reef food fish in Hong Kong are analysed using the Linear Approximate Almost Ideal Demand System (LA/AIDS). Results suggest that price elasticities of demand are inelastic, with relatively high-valued species exhibiting greater elasticity than relatively low-valued species. Cross price elasticities are negative suggesting that different...
Economists have generated numerous studies analyzing how a move to rights-based fishery management from open-access management affects fish harvesters' behavior. Conversely, the impacts that such a change in management can have on fish processors has received relatively little attention. This paper presents a simple two-product processor supply model to show...
A bio-economic model, based on Faustmann rotation, was developed to analyze the relevance of
removing thinning activities which are part of the dominant technology used in blue mussel production in
Canada. Removing these density control activities (thinning) seemed a profitable option to producers. It
was thought that this collector line...
The success or failure of aquaculture heavily depends on how effectively to manage aquatic animal
diseases. In order to analyze the economic effects of aquatic animal disease control, the specific factors
and magnitudes of benefits and costs are identified with and without the proposed project for the disease
control. These...
In natural resource economics, we sometimes observe a situation in which producers and consumers have
direct access to the factors of production or can use some consumable products with little or no
transformation. These goods are commonly referred to as “gifts of nature”. A factor of production is
considered a...
The exploitation of aquatic food products has been very fundamental as a source of livelihood in
the Sub Saharan Africa in particular and the world in general. Global production of aquatic food
products totaled approximately 93.2 million metric tons in 1997 and sub Saharan Africa
contributed 3.7 per cent. For...
The advent of scientific shrimp farming in India during 1990-91 was a turning point of shrimp production
in the country. Though scientific shrimp farming system renders higher level of production than the
existing traditional farming system, it is subject to certain criticisms especially for generating negative
environmental externalities. The conversion...
This paper sets out an evaluation of profitability differentials within shellfish farming activities of the
Mont-Saint-Michel Bay. The objective is to examine whether profitability differentials have
consequences in terms of economic dynamics and of management arrangements. The paper divides into
four parts. The first part presents a retrospective analysis of...
Assuming externalities from aquaculture to fisheries, we use a Verhulst-Schaefer model of fish
population-dynamics and production, coupled with an aquaculture production model, to investigate
effects on open-access and rent-maximising fisheries. Externalities are modelled by letting carrying
capacity, intrinsic growth rate or catchability coefficient in the fishery depend on aquaculture production....
The geoduck fishery in British Columbia has been managed by individual quotas since 1989. Individual
quotas have fostered a co-operative management approach in the fishery, which is implemented through a
non-profit society with membership made up of licence holders in the fishery. This non-profit society, the
Underwater Harvesters Association (UHA),...
The structure of wholesale and retail marketing catfish (Clarias gariepinus) were analysed in order to assess the degree of competition and understand the organization of the farm raised catfish (Clarias gariepinus) market in southwestern Nigeria, a major aquaculture fish producing area in Nigeria. The market was evaluated by considering the...
The efficiency analysis literature has long acknowledged the difference between program/policy effects and relative efficiency effects. The use of incentive compatible policy has been an important research agenda for fisheries economists, and Canada uses an array of policies and regulatory tools to fulfill the objectives of their Fisheries Act. One...
In this study, we tried to develop a theoretical framework based on the Schaefer model and establish bioeconometric models to estimate the index of fishery resources using cross-country macro data. The characteristics of our model are that we consider the effect of natural fluctuations of fishery resources over time (in...
