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...
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...
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...
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...
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...
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...
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...
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...
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...
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...
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...
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 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...
This paper is based on work that the authors have carried out on EU financed projects in the South Western Indian
Ocean (SWIO) in collaboration with the Indian Ocean Tuna Commission and the Indian Ocean Commission (IOC)¹ on a range of fisheries management issue including, stock assessment, tagging and monitoring,...
The concept of an ecosystem approach to fisheries management (EAF) is reaching a point of general acceptance by those involved in fisheries. There is also growing agreement that fisheries management must incorporate the complicated and often not-well-understood links between human activities and the environment. As a primary goal of an...
Many futures contracts for food commodities have been introduced; however, most of them have been withdrawn from the market due to poor liquidity. In this paper, various known success factors for futures contracts with regards to a proposed futures contract for salmon are discussed. Based on the various criteria from...
This study addresses the matter of logistic improvement of live food fish trade by economic analyses of pertinent information provided by the live fish traders in 2004 on three species of live fish: sand goby, sea bass, and grouper. The analyses take into consideration the logistics cost, break-even point, market...
The introduction of modern trawl fishing in Norway after the Second World War was intended to be the very platform for the modernisation of the fishing industry. Right up to the end of the seventies, market orientation and the absence of state regulation of fishing were on the agenda. However,...
In the context of the restriction of production, French agriculture modifies its activities by developing multifunctionality. This concept translates the fact that, beyond the saleable production of agricultural and food processing products, the agricultural activity fulfills other functions: economic, social, environmental. Multifunctionality of agriculture is implemented in a number of...
A key conclusion of 'Net Benefits' - the landmark 2004 strategic review of the UK fishing industry - was that a sustainable UK fleet must make long-run profits adequate to invest in new boats, improve safety levels, pay good wages for skilled staff and be able to survive in years...
This paper begins by outlining the history of the Rules of Origin negotiations in the World Trade Organization (WTO), unfinished business from the Uruguay Round that is separate from the current Doha Round. The treatment of products of the sea is one of a large number of unresolved issues; progress...
Lake Victoria is the worlds' second largest and Africa's largest fresh water body and shared by Kenya, Uganda and Tanzania. The Nile perch was introduced to Lake Victoria in the 1950s and experienced explosive population growth in the 1970s. Since the 1990s landings have been above or about 500 000...
Maximum sustainable yield (MSY) has been recommended as a reference point for fisheries sustainability. However, like other reference points it is generally applied on a single-species basis. This has potentially significant biological implications in a complex multispecies fishery. MSY-based reference points also have economic implications for fisheries prosecuting the resource....
Fisheries co-management is now well-established in the literature as a fisheries governance approach (e.g., Wilson et al, 2003; Hanna, 2003; Pomeroy et al, 2001). While co-management regimes have historically developed from the amalgamation of traditional community management with government authority (e.g., Acheson, 2003; Makino, 2005) However, another key insight is...
In spite of being one of the leading fish exporters, fishery resources in Thai waters had been degraded. Increasing fuel cost reduced a number of commercial fishing vessels in Thai waters. While trawl was the main fishing gear for commercial fisheries, their main catches were trash fish for fish meal....
This paper reports on an economic experiment conducted to examine the nature of rent dissipation in limited entry fisheries with aggregate quotas, and factors affecting fishermen's political support for changing to individual quota management. The experimental subjects are fishermen who participate in a series of fishing seasons. The experiment assumes...
Japan is considered as one of the most successful marine fishery co-management or CBFM regimes. However, in 2001 the Japanese government was obliged to introduce new measures in order to recover several species under overexploitation. One example is the Resource Recovery Plans (RRP) that in all Japan accounts 51 fisheries....
The 2005 Gulf of Mexico hurricanes devastated not only fishing boats but also many businesses interdependent with fishermen: processing plants, ice plants, boat builders, net makers and other suppliers. Fuel prices and other expenses have increased. Wholesale catch prices are down due to damaged markets, lack of storage facilities and,...
Fisheries regulations on fishing capacity are usually based on a nominal measurement such as limiting number of vessels of a fleet. However, the nominal measurement of fishing capacity has difficulty in capturing the actual fishing power enhanced by technological changes and potentially leads to biased measures on fishing capacity and...
Capture fisheries is a primary employment for inhabitants of coastal and inland aquatic ecosystems globally. However, historically, aquaculture has been well documented as an economic activity in Southeast Asia. Coastal marine fisheries and freshwater inland waters provided employment for inhabitants of these ecosystems in Sub-Saharan Africa (SSA). Aquaculture was started...
According to the objective of stock recovery defined at the summit of Johannesburg, the optimal management of fisheries requires adequacy between the available resource and fishing capacity. However, matching this objective with another goal of economic and social sustainability is also of major importance. Data Envelopment Analysis (DEA) methods are...
