A study was conducted to understand current practices of commercially important marine fish marketing systems in the Patuakhali area of southern Bangladesh. A total of ten commercially important marine fish were identified such as: 1) hilsa, 2) pomfret, 3) marine catfish, 4) tuna, 5) coral fish, 6) marine eel, 7)...
This paper considers the implications of the sustainability agenda for seafood processors
in the UK. A systems approach, using the value chain system as the conceptual
framework, is adopted to capture the multifaceted and often subjective nature of
‘sustainability’ and accommodate the changing nature of competitive advantage. It is
concluded...
New Zealand manages commercial access and allocation through the market-based Quota Management System (QMS). However, the QMS alone is currently insufficient to address several fisheries issues. New Zealand is now developing Objectives-Based Fisheries Management (OBFM) to complement the QMS along two dimensions. First, to improve fisheries outcomes, such as reduced...
This paper presents the interim results of an ongoing research project funded by the 'Research Councils
UK' Rural Economy Land Use programme. The project has a multi-disciplinary perspective on the
potential production and marketing of tilapia as a niche product under a diversification strategy for UK
arable and dairy farmers;...
Shrimp farming in Thailand is considered to be one of the main causes of mangrove deforestation. The Environmental Kuznets Curve (EKC) hypothesis, however, posits that economic development eventually reverses resource degradation. This hypothesis is examined using pooled data on mangrove loss and Gross Provincial Product (GPP) from 23 provinces in...
Because of wild salmon's importance as a commercial fishery in North America, many questions and concerns have been raised around the issue of farmed versus wild salmon in recent years. Concerns have been related to the impact of the tremendous growth in farmed salmon production on the markets for wild...
The question of how to discipline fisheries subsidies is a major issue at the forefront of the international fisheries policy agenda. The negotiations underway at the WTO to clarify disciplines on fisheries subsidies, and the call in the WSSD Plan of Implementation to eliminate subsides that contribute to illegal, unreported...
In 2004, United States (U.S.) shrimp landings comprised 11% of shrimp available to the domestic market. Asian and
South America shrimp imports to the U.S. began reaching record levels in 2001, following European Union tariffs
on Asian shrimp. The increased import supply resulted in drastic decline of ex-vessel and wholesale...
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...
Indicators of the economic performance of fishing vessels are frequently computed in many countries. Usually, measures of economic performance are based on the return on capital invested. However, several measures of capital value exist, according to the economic information available. In this paper, we use different types of information to...
The economic results of fishing harbours are a key issue for the sustainability of coastal economies. To deal with it, three harbour branches need to be analysed : the suppliers of goods and services, the fishing companies and the trading actors. The compatible state with constraints, various interactions and behaviours...
Fishmeal prices have increased sharply since the mid-2005 and the relationship between the prices of animal and vegetable proteins have become weaker, at least temporarily. This can be explained by a relatively constant fishmeal supply, which have varied around 6-7 million metric tons the last two decades, and an increasing...
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...
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...
Fishing communities have always had an obvious economic interest in fishery management as it affects their short-run and long-run prosperity. Many fishing communities are now interested in a more active role in the form of co-management, community-based management, or community property rights. The primary research focus in communities and fishery...
The security of world fish supply from wild fisheries and from aquaculture is an increasing concern due to dwindling yields from wild catch and undesirable ecological impacts of aquaculture. The extent to which aquaculture can substitute for fish from wild catch will depend on the productivity of aquaculture, which in...
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...
The current Senate Bill to reauthorize the Magnuson/Stevens Act, the key US fishery management law,
will allow some significant changes in the way that Individual Transferable Quota programs can be
developed. First, the bill will expand the range of individuals who will be permitted to obtain harvesting
privileges. In addition...
World fisheries are characterized by ecological, economic and social costs which are not taken into account by current market mechanisms. However the sustainability of ecosystems and fishing activities depends on their taking into account in order to take the most suitable management decisions. Based on the consilience concept, the European...
Fisheries is not the only discipline where models have been used in attempts to fine tune an aspect of the economy. Such fine tuning can prove ineffective because of the uncertainties in the scientific underpinnings of the models and because of the omission of critical elements. In fisheries, the biological...
The field of marine resources management is very broad and diverse. It is also very dynamic as new and
exciting research is being produced in emerging fields such as aquaculture and integrated management.
This research proposes to evaluate the trends in research pertaining to the many fields within marine
resources...
Resource rentals can be viewed as taxes on scarcity rents or as fees for access to use or utilize the
resource. The Icelandic Fishery Management Act requires that vessel owners pay a Catch fee
(Veiðigjald). This paper discusses how the Catch fee is defined by the Fishery Management Act.
Secondly...
Community fishery rights are use rights (the right to take part in fishing) and/or management rights (the right to be involved in managing the fishery) implemented at a local, community level. While by no means a new invention, community rights are receiving renewed attention as a mechanism to improve the...
Linear approximate almost ideal demand system was employed to estimate demand for Thai frozen shrimp in the United States of America, the main importing country for Thai frozen shrimp. Import demands for the same products from Bangladesh, China, Ecuador, India, Indonesia, Mexico, and Vietnam were simultaneously estimated to compare with...
Days at sea restrictions were introduced in 2003 as part of the cod recovery strategy in the North Sea. The impact on the profitability of the fleet of the effort controls, however, is not immediately discernable, as the fishery was also subject to changes in costs, prices and stock conditions....
The optimal harvesting time in a fish farm is analyzed in the paper. Fish population is assumed to be heterogeneous with respect to weight, so a distributed parameter dynamic model is considered. Theoretical and numerical results are obtained and compared with the ones concerning homogeneous fish cultures only. The results...
We study the combined effects of periodically varying carrying capacity and survival rates on the fish population in the ocean (sea). We introduce a new delay differential equation model with a control parameter which describes how fish are harvested.
We consider a predation function as the function of the delayed...
Seafood is a staple for most Sri Lankans and the country is a net importer of seafood, because of the
heavy consumption. Tsunami has had crippled the Sri Lanka’s main protein supply system and
thousands of others in marketing chain lost their jobs. The main focus of the study was...
Several factors contribute to the productivity of nations' fisheries: (1) The biophysical conditions that determine the abundance of fish stocks, (2) government regulation of fisheries, and (3) innovation and adoption of (i.e. investments in) new fishing technologies. This paper analyzes the long-run productivity performance of three Nordic countries Iceland, Norway...
"Slipper skippers", "absentee landlord" or "absentee ownership", "fleet separation policy"... All these expressions describe a single feature: the separation between two economic functions, ownership (who gets the right to access the resource) and production (who exerts the right). This issue is considered as highly sensitive in several places, such as...
This paper, that follows from the ongoing Ecost project, departs from the reality of marine biodiversity degradation in the Caribbean. It first enquires how local fishing communities appreciate and measure the degradation of marine biodiversity. In this connection, it asks whether communities have social and cultural attachments to particular species....
The New Zealand Ministry of Fisheries recently set out a strategic approach to managing the adverse effects of fishing on the aquatic environment. The primary purpose of this Strategy for Managing the Environmental Effects of Fishing (SMEEF) is to set out how the Ministry of Fisheries will meet its environmental...
Coastal areas in Southeast Asia have historically been globalised spaces, with land and resources such as
fisheries influenced by trade since pre-colonial times. As the intensity of resource use has expanded the
resilience of the coastal environment and effectiveness of management practices have come into question.
Commodity chains that once...
NOAA’s National Marine Fisheries Service (NMFS) was a key participant in the FAO technical and policy-level consultations of 1991-1999 that led to the FAO International Plan of Action for the Management of Fishing Capacity. The U.S. Plan of Action includes a commitment to prepare regular assessments of overcapacity in federally-managed...
Restrictions on flows of foreign direct investment (FDI) in most sectors of OECD countries have been significantly reduced in recent years. In contrast, FDI in the fish harvesting sectors of OECD countries is still heavily restricted through a range of measures including outright bans on FDI, maximum allowable levels of...
The Southeast U.S. shrimp harvesting sector is one component of the shrimp industry that has generally been unable to make the adjustments needed in response to the growing import base and the resulting supression in prices. Not unexpectedly, therefore, requests for relief from the perceived problems associated with increasing imports...
This paper presents the findings of a field survey carried out within small scale fishing communities on the island of Zanzibar in 2004. The study was designed to assess the impact of the Menai Bay marine protected area on the livelihoods of fishing households located within its boundaries using the...
Individual fishing quota programs are increasingly being used to establish property rights in commercial fisheries in the U.S. These programs are intended to promote resource conservation while improving economic efficiency. However, these rationalization programs are often criticized for their distributional consequences. In the Gulf of Alaska halibut fishery, there is...
The marine fisheries sector in India is currently going through a phase of socio-economic cum ecological turbulence.
The rate of growth in marine fisheries production, as evidenced by recent studies, is plateauing, if not, declining.
The need for initiating management options that promote sustainable resource utilization and stable livelihood
security...
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...
Key decision variables in aquaculture management are stocking level, feeding schedule, temperature
control and batch length. In many management problems with an infinite planning horizon, the aim is to
find the batch length which results in maximum return if the same batch length applies to all future
batches. This may...
Accounting for endangered and protected sea turtle interactions with the pelagic longline fishery by the fishery management has become an important policy goal recently. A multi-objective programming model for Hawaii's longline fishery that incorporated sea turtle interactions (Pradhan and Leung, in press, Ecological Economics) has been extended with spatial and...
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...
Community quota schemes (CQS) have been introduced in some UK fishery dependent areas in an attempt to address the detrimental effects of the current market based approach to quota management. The most established and largest scheme operates in the Shetland Isles, where there was concern quota holdings could be traded...
On the morning of 29 August 2005, Southeast Louisiana was decimated by the winds and flood surge associated with Hurricane Katrina. Shortly thereafter, Hurricane Rita played havoc on the Southwestern part of the state. Louisiana's commercial seafood industry, already on the decline for a number of reasons, including declining output...
In the 1990s the North Pacific Fisheries Management Council and the National Marine Fisheries Service established regulations to limit the amount of Chinook and chum salmon taken as bycatch in Bering Sea trawl fisheries. The Bering Sea pollock fishery has in recent years (2002-2005) caught a significant number of sockeye...
In the world, Japan has a special place in the fish consumption, as Japanese people are among the most important consumers of aquatic food products, and Japan ranks first as fish importer, for supplying about half of its market. Thus the changes in the Japanese seafood market are susceptible to...
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...
We describe the first effort at creating a global ex-vessel fish price database. We then demonstrate potential applications of the database by linking it to the Sea Around Us project's spatially defined catch database, which makes it possible to attach catch values to species both in time and space. There...
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...
