The Norwegian government has recently put forward a white paper concerning the management of the red king crab in the Barents Sea. The crab is an introduced species in the Barents Sea. The motive of the introduction was to improve the economy of the Russian coastal fisheries, as the crab...
Entrepreneurial New Zealand harvesters created a viable diving fishery for King Clams, Panopea zelandica, in the 1970's
contributing to the development of allocation rights to harvest. Once under the quota management system (QMS), however,
allocations for allowable catch do not reflect the harvest potential for this fishery. Expectations for quota...
The red king crab (Paralithodes camtschaticus) is an alien invasive species in the Barents Sea representing a value as well as a potential pest. A bio-economic model is applied analysing the costs that traditional fisheries incur as a result of the king crab invasion, as well as the income from...
The paper seeks to identify bioeconomic patterns and processes with respect to the Red King Crab (Paralithodes camtschaticus) in the Barents Sea. Its dual role (as invasion and market commodity) together with the dynamically evolving Arctic marine environment requires pro-active and multi-faceted approaches. Challenges and uncertainties include data limitations, scientific...
The global trade in both fish commodities and fisheries services has expanded significantly in the past 10 years. FAO estimates that the current value of the international trade in fish commodities is over US $80 billion per year (fish is the most valuable traded agricultural commodity). Fisheries services are less...
Bycatch of non-targeted species in marine fisheries has become a major policy issue in fisheries management over recent years. One approach to curbing the bycatch problem is the voluntary sharing of detailed spatiotemporal information between vessels as an aide in individual bycatch avoidance as well as a tool to lower...
Increased attention is being given to the promise of co-management as a means of achieving sustainable
fish stocks while at the same time providing benefits to those dependent on the fishery. At the same time,
the view that co-management represents a continuum between state or user control is being replaced...
The Traditional Management of Artisanal Fisheries in North East Nigeria project (TMAF) has been funded by British Overseas Development Administration (ODA) to investigate the possibilities for designing a more effective management system for fisheries of the Sub-Saharan Savanna region using a community-based approach. The need for a new approach is...
Capture fisheries can potentially provide a wide range of social benefits, many of which make important contributions to local livelihoods and national economies. However, in practice, and in many representations of fisheries, the starting point for assessment is the biological, fish, element of the system and its production potential. The benefits...
A central objective for UK Department for International Development (DFID) funded research on
renewable natural resource systems has been that the research commissioned results in significant positive
developmental impacts. This paper describes the outcomes of activities employed by the DFID funded
Fisheries Management Science Programme to assess the developmental impact...
The following paper presents the results of a detailed investigation into the distribution, characteristics and performance of fisheries management systems in the major fisheries of north-east Nigeria (Upper River Benue, Lake Chad and the Nguru-Gashua Wetlands). A key focus of the research was to examine the possibilities for using a...
There has been a long-standing interest in local knowledge in fisheries research and management. Much of this interest has been in terms of how local knowledge can be interpreted scientifically and used by fisheries experts and managers. Local knowledge becomes the property of scientists, wrapped up in a format and...
Tuna and other highly migratory and trans-boundary fish species form an important seasonal component of the annual catch taken by thousands of small-scale inshore and coastal fishers in the Bay of Bengal region of the Indian Ocean. However, there are serious concerns about the productivity and sustainability of the fisheries...
An integrated model combining a wildlife population simulation model and timber harvest and growth models was developed to explore the tradeoffs between the likelihood of persistence of a hypothetical wildlife species and timber harvest volumes on a landscape in the Central Oregon Cascades. Simulated annealing, a heuristic optimization technique, was...
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...
It is rarely possible or desirable to maintain a constant target fishing mortality rate for each individual stock in a multispecies fishery. Preventing overfishing of all stocks at all times will often be in conflict with attainment of optimal yield for the fishery. This paper presents a retrospective analysis and...
The importance of land infrastructure for supporting coastal fisheries has long been acknowledged; its role in remote and geographically challenged fishing communities in the Nordic Arctic has visibly impacted community structure and development. This paper explores the Red King Crab (RKC) fishery in Norway and the ways in which its...
The importance of land infrastructure for supporting coastal fisheries has long been acknowledged; its role in remote and geographically challenged fishing communities in the Nordic Arctic has visibly impacted community structure and development. This paper explores the Red King Crab (RKC) fishery in Norway and the ways in which its...
Almost all recent empirical literatures that study the subjective wellbeing of fishers lack of relevant control as they are only based on surveys among fishers. Therefore, they cannot really answer whether being a fisher generate higher or lower life satisfaction, after controlling for other aspects of life. This study is...
The clam, Galatea paradoxa has for decades been an important source of protein to the riparian communities of the lower Volta River and provides employment to about 2000 people, especially women. The fishing grounds have dwindled from 100 km from the pre-dam era to a narrow stretch of 10 km...
In 1998, the Florida Keys National Marine Sanctuary initiated the “Tortugas 2000” planning process that would lead to the eventual designation (2001) of the largest marine reserve in the US: The Dry Tortugas Ecological Reserve (DTER). This resulting research, targeted commercial fishermen operating in the DTER region, determining the total...
The National Marine Fisheries Service (NMFS) is mandated by law to analyze the benefits, costs, and economic impacts of the recreational fisheries policies it promulgates. NMFS has developed single species models that predict welfare and effort changes stemming from changes in various recreational regulations. Little is known, however, about angler...
Fisheries management involves considering several biological, economic and political objectives. They are often contradictory. For this reason, it is almost impossible to reach them simultaneously. Andalusian regional government collaborates with the national government to establish fishing plans for local fisheries. The objectives of these plans verify the aforementioned statement. For...
Scallop fishing was in effect a regulated open acceess fishery in UK until 2012 when the Western Waters management regime was implemented, limiting the maximum effort for the UK fleet of over 15m vessels and, via the UK government, limiting effort per vessel over 15m. This analysis identifies the main...
This paper explores the political economy of using fishery cooperatives to advance voluntary decapitalization and rationalization that the U. S. Congress intended to benefit both vessels and processors. Game theory offers insights into the likelihood of achieving congressional intent. It is argued that the American Fisheries Act introduces a potential...
A two-stage, distributionally neutral and efficient rationalization policy design—one that preserves the ex
ante wealth distribution—is developed by blending elements of a cooperative and a partnership. It is
formally proven that there is no impediment to win-win rationalization using only IFQs allocated only to
harvesters. The design creates a bilateral...
In “Landing fees vs. harvest quotas with
uncertain fish stocks”, Martin Weitzman maintains that
the conventional view among both fisheries economists
and fisheries managers is that “prices” are inferior to
“quantities” as instruments for regulating the fishing
industry. Weitzman takes the opposite position,
appealing to two well-established ideas in economics:...
Situation: UK scallop fishing is input measures, with effort limits applied to >15m vessels only. There are no output limits. Industry members noted a decline in profits, and suggested that the effort regime was to blame. Government asked for evidence to support the claim and asked Seafish for economic analysis...
Following an assessment of Mexican water resources by governmental agencies in the late 1940’s, Tabasco State was identified as a potential area for aquaculture development, as the State holds 30% of National water resources and an important share of Southeast Mexican fisheries, particularly for oyster production. However, conflicts and competition...
This paper deals with the application of a dynamic model, combining Transaction Cost Economics (TCE) and Penrose’s theory of the growth of firms, under the New Institutional Economics (NIE) terms, to analyze and manage the “Agribusiness Innovation System” (SIE) coordinated by an agricultural research-development (R&D) organization in Brazil – Embrapa....
Aquaculture is increasingly important for the future supply of fish because of steadily increasing demand while supply from fisheries is stagnating. In the EU aquaculture production has grown strongly in some countries, such as Spain and Greece, but was flat at a low level in others, such as in Germany,...
This presentation describes the impact of transitions to catch share management on risk-taking among commercial fishermen in three fisheries. Catch share management has been associated with a decline in the speed and intensity of fishing activities and longer fishing seasons. This is expected to improve safety in fisheries. Using wind...
For US aquaculture industry, primary factors influencing their competitiveness are consumers' perceptions of long-term health risks related to domestic farmed seafood consumption. The public is often particularly sensitive to food risk scares, and can often dominate other considerations in food choice and lead to large impacts on consumption and the...
Over the past century, the tuna canning industry has been dominated by a few big companies, some of
them having changed of ownership or merged: these oligopolistic firms are the “big three” in the USA,
Van Camp, Star Kist, and Bumble Bee, the French Saupiquet, the Italian Trinity Alimentari and...
Thailand is the biggest shrimp producer in the world. Thai shrimp from aquaculture reached 280,000 tons in 2001, which accounted for about 33% of the total global shrimp aquaculture production. Detection of residues of banned chemicals in shrimp imported to Europe from Asia starting from 2002 was perceived as a...
Global Trends: Foreign and transnational ownership (& ownership interests), Complex structures: vertical integration, flags of convenience, joint ventures, etc., Concentration: a handful of corporations controlling global fisheries (Österblom et al. 2015,Carmine et al. 2020). Why Regulate?: Risk of monopolies and market failure, Governance of corporations (i.e., compliance, enforcement), Who captures...
Substitution and elasticity give about the history of supply and the demand structure for fish and seafood. It is also relevant to the detection of change in a particular exploited marine ecosystem. The purpose of this paper is to test if market elasticity of substitution of seafood categories can further...
The Fishermen Guilds in Spain (Cofradias) have around one thousand year tradition. They play a central role in the control of the fishing rights in special in the context of coastal fisheries. The paper examines the mechanisms to establish property rights, the quality of these rights and the cost and...
The profitability of the Mediterranean mussel (Mytilus galloprovincialis) farming depends on a combination of factors including natural productivity, technical practices, production costs and product pricing. In an effort to analyse the financial risks of the mussel farming in Greece, we examined the profitability of the different farm sizes (1 to...
The positive relationship between innovation and an unusually high concentration of ownership is considered in relation to the Exmouth Gulf Limited Entry Prawn Fishery. Innovation has lead to the adoption of improved harvesting practices and the investigation of the potential for stock enhancement. Experiences in this fishery are consistent with...
Proceedings of the Eighteenth Biennial Conference of the International Institute of Fisheries Economics and Trade, held July 11-15, 2016 at Aberdeen Exhibition and Conference Center (AECC), Aberdeen, Scotland, UK.
Western Australian (WA) fisheries have a long association with environmental certification- the WA rock lobster fishery (in 2000) was the first fishery certified under the Marine Stewardship Council (MSC) standards.In 2012 the Western Australia Minister of Fisheries announced that the State Government had committed $14.6 million across a four-year period...
Since proposing “Sustainable development” defined by World Commission on Environment and Development, many organizations (governments, industries and NGOs) have sought and tried sustainable way of shrimp aquaculture. As the mangrove was destroyed on a large scale, they have tackled to mangrove reforestation around the same time. Destruction of the coast...
