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...
The use and management of fish supplies, fish stocks and those who work in fishing and related businesses needs to be governed by good policies and actions, based as far as possible on good research-based advice and other expert information. Fisheries policy makers and managers work in a milieu that...
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...
At the 2001 WTO Ministerial Conference in Doha, World Trade Ministers called for improved disciplines on fisheries subsidies, given the perceived impact of these subsidies in contributing to overfishing, overcapacity and other trade distortions. Subsequent deliberations have sought to determine which fisheries subsidies should be disciplined under the WTO framework....
Earlier this year a White Paper from the Norwegian Minister of the Environment presented a new, holistic, area-based management plan for the Norwegian part of the Barents Sea, including the Fishery protection zone around Svalbard. The plan will provide guidelines for managing human activities in relation to their use and...
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 outcome of the current multilateral trade negotiations in the Doha Round will have large implications on international fish trade. The author highlights the most likely scenarios in areas such as market access and fisheries subsidies, and outlines the very diverse interests and negotiation positions of WTO members.
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...
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...
Maximizing profit and value added are central objectives when fishing rights are distributed. Financial profitability on a company level traditionally measures the return on total assets. Value added on the national level is the net (or gross) national product, and is the total profit of investments and wages and salaries...
To the surprise of government as well as NGOs, village-level caste organizations - or panchayats - played a significant role in the post-tsunami relief effort to fishermen in Tamil Nadu, India. This paper discusses the pro-active role of caste panchayats in relief from the perspective of social resilience, that is...
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 wide expanse of the sea, the inter-linkages among, and the productivity of its resources have until recently led most researchers to consider it unrealistic that humans could have more than local impact on marine ecosystems and their biodiversity. This perception is changing, however, as more evidence of the scale...
A rapid increase in the Thai trawl and push net fisheries had led to over fishing and thus fishery resource degradation. Catch per unit effort decreased from over 300 kg/hr in the past 30 years to less than 20 kg/hr recently. The impact has placed a greater burden on coastal...
Overcapacity situations appear regularly in the activity of marine natural resource exploitation. The measure of capacity utilisation and allocative efficiency for fishing vessels is an approach that can determine the details of that overcapacity. On the one hand, DEA (Data Envelopment Analysis) methodology can be used in the case of...
Under the provisions of the United Nations Convention for the Law of the Sea (UNCLOS), coastal states must provide for access to harvest the living resources within their EEZs. Where the state does not have the capacity to harvest the entire sustainable catch, it must grant other states access to...
The International Plan of Action for the Management of Fishing Capacity (IPOA-Capacity) was introduced in 1999 in response to growing concerns about excessive levels of fishing capacity and its impact on global fisheries resources. While debate in academic circles has focused on appropriate ways in which to measure capacity, the...
In this paper, we illustrate characteristics of food system of tuna by making a bird’s-eye view of tuna
trade and global distribution. Tuna resources are primarily consumed as canned tuna or Sashimi (=raw
fish). The fishing methods and species predetermine the food system of the caught fish. Among seven
tuna...
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...
The animal protein intake in Nigeria is grossly insufficient yet the retail price of fish is rising. Market intermediaries, alleged to charge excessive and unjustifiable marketing margins (MM), are often blamed for this. This study examines this allegation using data from 225 sun-dried fish traders classified into three groups. Data...
Fisheries managers around the world have identified bycatch as a key management challenge in fisheries today. However, like the classic common property open-access problem in fisheries, a limit on fleet-wide bycatch may have similar consequences for fishing practices since bycatch is a common property open-access resource. If avoiding bycatch is...
This is a study on economic implications of the 3 year harvest control rule (HCR) for the Northeast Arctic
cod stock, decided in November 2002 by the Joint Norwegian-Russian Fisheries Commission. Outcomes
of this rule are compared to those of five other rules, including the previous one based on a...
European eel (Anguilla anguilla) is one of the most important commercial species in France (eel larvae (glass eel) exports to Asia valuing more than 60 million euros in 2005) but also an endangered species with regard to the dropping recruitment. This species is particularly sensitive to oceanographic and climatic factors...
With the increase of population and depletion of fisheries resources due to loss of fish growing land to agriculture, siltation, etc it became necessary to develop an institutional set-up for fisheries education and research. A number of educational institutes have been established in Bangladesh and every year a number of...
In many salt-water recreational settings an imprecise measure of site choice is often collected based upon the individual's launch-point. For anglers who continue on from the launch-point in a boat, this imprecise measure of site choice is likely missing important on-water trade-offs thereby affecting the accuracy of recreational benefit measures...
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...
Global warming is expected to affect the ecosystem in the Northeast Atlantic, and sufficient changes will also affect
the aquaculture industry. Farming of salmon and trout is the biggest aquaculture industry in Norway. The export
value was about 2 billion US dollars in 2005. The objective of the paper is...
This work analyses empirically the exploitation dynamics from 1997 to 2003, of the most important
segment of the Spanish fishing fleet operating in the EU waters, also known as “300 fleet”. The aim of the
analysis is exploring the economic consequences of the coming into force of the new approaches...
The federal and state governments have many different roles to play in addressing the regional impacts of hurricanes. Ranging from hurricane prediction and preparedness to damage assessment and economic recovery, the role of the federal government is one of ensuring human safety and providing for the protection of private property....
A number of simulations have been carried out to study different management scenarios in the Barents Sea cod fisheries when implementing physical and biological effects of global warming. A regional representation of the IPCC SPRES B2 scenario (world region OECD90) has been obtained through the REMO5.1 model. Water temperatures and...
Any model of an exploited ecosystem necessarily includes a representation of fisheries activity as argument(s) of the function(s) describing the state of the ecosystem. Hence the definition of this argument (e.g. effective fishing effort(s), fishing mortalities, Yields&) mainly results from the chosen ecosystem model, with a dimension generally equal to...
An economic assessment of the commercial harvesting sector, seafood processing and distribution
sectors, charter boats for hire, livebait boats and dealer houses, marinas, support facilities, and
recreational boats was undertaken in Mississippi to determine the level of damage sustained as a
result of Hurricane Katrina. The devastation by this hurricane...
Four commercial fisheries off Alaska’s coast are managed by transferable quota systems. Implementation
of each quota program was controversial, and two programs were mandated by federal legislation rather
than standard rulemaking procedure. Pacific halibut and sablefish are managed by individual harvest
quota programs, which were designed to maintain a predominantly...
While the need to solve problems of overcapitalization and excess investment in fisheries is now broadly
admitted, very little information exists on the level of capitalization and the structure of capital invested in
the fishing sector. This paper presents the first results of a research program aiming at assessing the...
Within the fisheries literature there has been a growing interest in obtaining estimates of fisheries production in order to determine vessel specific measures of technical efficiency that may be used to estimate the capacity of the fleet. Given that many data sets are panels there has arisen a growing need...
Atmospheric measurements show that so-called greenhouse gases have been accumulating in the
Earth’s atmosphere for well over a century. There are strong indications that human activity
plays a significant role in this process. One consequence of the accumulation of greenhouse
gases is thought to be an increase in global temperatures...
Ocean temperatures are expected to rise over the next decades. This is likely to affect the distribution of fish stocks between the exclusive economic zones (EEZs) of different countries. Such changes are likely to be triggered as temperatures rise beyond certain threshold levels, and they are likely to be irregular,...
The eastern Georges Bank haddock resource is shared and managed by the U.S. and Canada through a transboundary resource sharing agreement. This agreement includes an annual process for joint stock assessment, setting of a TAC, and harvest shares for each country. The resource sharing agreement provides a mechanism for establishing...
A wide range of fisheries are managed using vessel catch limits combined with different kinds of effort restrictions. This management framework is expected to have desirable consequences for the bioeconomic sustainability of fisheries. When appropriately implemented this approach produces outcomes that are similar to those associated with individual fishing quotas....
Recent results from a vector error correction (VEC) analysis indicate that El Niño-Southern Oscillation (ENSO) events appear to affect both red snapper landings and effort in the Gulf of Mexico headboat fishery (Carter and Letson 2005). A key finding is that the outcome of policy changes can vary depending on...
Efficient management of natural resources hinges on our ability to monitor and assess the status of the resource stocks as well as the actions and economic performance of the agents utilizing such resources. The sustainability and viability (both in physical and economic terms) of our resource management plans can in...
The optimal management of the European hake fishery (southern stock) is analysed. Since
the activity of the fleets has different impacts on marine resource in this fishery, depending
on the selectivity of their gears, the degree of selectivity is included in the analysis.
Likewise the changes in the selectivity of...
Tsunami catastrophe has had devastated ten main fishing districts of the country and which account for 72% of the
marine landings. The tsunami affected areas are very important for commercial tuna fisheries and fish landings
(except shrimp aquaculture), fleet operations and livelihood of fishermen. The purpose of this study was...
There is much talk on recycling organic effluents, closing nutrient cycles, maximising energetic efficiency, and maintaining
equilibriums between humans and nature, etc., even for lakes and estuaries. Aquatic systems provide us (humans)
the service of recycling decomposable organics and deliver fish at the same time, notably, as long as the...
