Fisheries models are generally built to assess the dynamics of a resource with a given fishing mortality
which level can be decided by some “decision maker” and/or which can be an observed process, e.g. times series proportional to some observed values of fishing effort. In these cases, the resource dynamics...
Despite potential advantages of rights-based management over competitive fisheries, there has been significant political resistance to rights-based management from many fishermen, which has slowed the
adoption of rights-based management. This paper explores the concept of voluntary transitions to rights-based
management, under which fishermen may choose between an allocated fishery (with...
This paper explores some theoretical and practical issues in developing policy for the management of shared fisheries for maximum value. Maximisation of value from the use of resources is a key component of sustainability, and transferable rights in commercial fisheries management have contributed significantly toward this goal. Maximising value becomes...
The long history of the van chai system of Vietnam began several centuries ago with their establishment mainly in the lower and middle reaches of rivers northern Vietnam and in coastal lagoons in Central Vietnam, whereas those in marine embayments, like Ha Long Bay, and in enclosed coastal areas, like...
In agriculture there has been a long history of using a levy or an insurance premium to create mutual funds to mediate economic risks to growers due to environmental variability and quarantine pests. In the United States the federal government, through the USDA, continues to underwrite funds (collected by private...
This paper studies the potential for cooperation in shared fisheries when the countries in the coalition act in a Stackelberg fashion with respect to the remaining singletons. An increase in the cooperation level is a social welfare improvement, leading to an increase in both the steady-state fish stock and total...
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...
This paper formulates a simple biomass growth model of a fishery. The property rights regime is of the unregulated local common property type with a fixed number of fishermen and where the fish stock is exploited in a myopic profit-maximizing manner. Within this resource management setting it is demonstrated that...
The hilsa shad (Tenualosa ilisha) fishery is by far the largest single species fishery in Bangladesh. In this paper, a simple bio-economic year-class based model is developed to describe the fishery and examine its properties. With the help of this model, the optimum sustainable yield of the fishery is calculated...
This pilot study maps the structural changes in the Icelandic fisheries sector from 1990 to present, from the general to the specific. The background is the radical and substantial changes in the structure of harvesting, production and processing; in the export activities and marketing in Icelandic fisheries. The main characteristics...
Vietnam is in the club of countries gifted with the long coastal line, and strong in marine features accordingly. Fishing operations are artisan characteristic and the management method is primarily open – access. Since the past few years, the yellow fin tuna long- lining fishery has become one sub-sector experiencing...
The overall objective of SPICOSA is to develop a self-evolving, holistic research approach for integrated assessment of Coastal Systems so that the best available scientific knowledge can be mobilized to support deliberative and decision-making processes aimed at improving the sustainability of Coastal Systems by implementing Integrated Coastal Zone Management policies....
In many fisheries, the harvesting pattern shows considerable intra-year variation. These fluctuations give
challenges for downstream firms in value chains where predictability and continuity in the flow of production are important. Seasonal harvesting may well be rational from an economic perspective, as migration patterns can give huge variations in catch...
Unlike the North and the South where abundance of freshwater, the marine capture fisheries is underdeveloped, the Central Coast, especially South Central Coast with little freshwater fisheries resources, but high amount of shrimps, fishes at sea, thus local fishermen have exploited this resource for living early. Together with this living...
This paper briefly describes the past development of the Bali Strait small pelagic fishery, and presents the impact of increasing fishing pressure and climatic variable on the quantity of catch. This paper then presents an estimate of its rent potential and the impact of increasing fishing pressure on rent at...
In order to provide a rationale and mechanism for implementing responsible fisheries in practice, this paper examines the effect of establishing Regional Fishery Management Organisation (RFMO) with effective enforcement on cooperative possibilities in shared fisheries. The result shows that an increase in cooperation level is a social welfare improvement, and...
The year 1990 saw the introduction of individual transferable quota rights to the NZ rock lobster fishery. This paper presents an analysis of the evolution of profitability in five different quota management areas over the period 1990-2001. The bio-economic model of an optimal fishery provides the basis for econometric analysis....
Kattudel or stake net fishery is an ancient (from early 1950s) lagoon fishing technique in many regions of Sri Lanka. It drags special attention due to the absence of open access nature. The fishery is regulated by kattudel association stemming from the Catholic Church. In fact, the fishery has its...
Society has agreed on the goal of sustainable fisheries but achieving the goal is often submerged by more
immediate national and international demands causing fisheries to slip down the political agenda or diverting attention to other fisheries issues, e.g., profitability under high fuel prices. Among the problems
challenging marine capture...
Co-management has attracted considerable attention around the world, including in Vietnam. However, debates on the concept of community-based management (CBM), co-management (COM), and community participant management in Vietnam are increasing, and the abundance of projects in Vietnam has now become a major constraint. Although most pilot co-management projects are recorded...
Quality safety traceability system has adopted by most fishery enterprises as an important part of the strategic management. As the consequence, the end product is supposed to be higher. That consumers whether to accept has a direct impact on system successful implementation. This paper proposes a framework to research consumer...
Fishing for the life reef fish has been an important source of economy both at macro level and micro level. At Macro level, life reef fish for food (LRFF) plays a greater role in increasing export revenue since most of the fish are sold in overseas markets such Hong Kong...
Local community in the Mekong Delta is said to be “fish eating society” where 70% of their animal protein relies on fish products. The Mekong Delta contributes more than 60% of total aquaculture production and 40% of total wild fish catch of Vietnam. Among a large number of fishing boats,...
This study extends Theory of Planned Behavior (TPB) to investigate the motivation to consume fish in a representative survey of Vietnamese individuals. The emperical study is based on using the structural equation approach to test construct valitidy of measures and the emperical fit of theoretical model. The results show that...
Marine Protected Areas (MPAs) can be considered as one of powerful conservation tools of fishery resource management in the literature. However, due to continuing environmental awareness and mismanagement, the Philippine government has decentralized the power of legislation and management of its MPAs since the early 2000. This encouraged participation of...
Over fishing is one of the obstacles faced in managing sustainable fishery resources. Even though various management instruments to control fishery resources have been in place, most of the time these instruments are not effective to curb over fishing especially in developing countries where poverty in coastal communities is still...
The shrimp fishery accounts for more than one-half of the total revenues generated by commercial fishing activities in the U.S. Gulf of Mexico. Due to its historical open access nature the harvesting sector has historically been overcapitalized (from an economic perspective) resulting in a suboptimal generation of rents. Various management...
A debate is emerging over the extent to which privatization of fishery resources – private ownership and resource management without significant state oversight- is practical and socially desirable. What we term the “optimists” maintain that there are no effective limits to privatization and that the decades old fear that privatization...
In 2006, Viet Nam’s fishery sector contributed about 6.1 percent to the GDP of the country and the value of aquatic products in export turnover was about US$ 3.3 billion. This accounted for 9-10 percent of the country’s total export value (MOFI/USDAFAS, 2007). Home consumption of fish has increased from...
Van Chai are traditional fishing associations in Binh Dinh province, mainly distributing in coastal areas. In spite of experiencing many ups and downs, suffering great impacts of market economic and cultural integration, these villages still exist until now. However, many cultural features of the Van Chai have been gradually lost...
Fisheries are increasingly important in the world with growing demand for fish in China, Western, African and Asian countries. Many people depend on fisheries and will be benefited from fisheries. Many governments took fisheries promotion policies after the 1970s when the UN 3rd Law of the Sea Conference developed. However,...
There is growing recognition worldwide that the impacts of fishing on non-targeted components of marine ecosystems should be included in the assessment of fisheries sustainability. This leads to the inclusion of new constraints in evaluations of the long-term bio-economic performance of fisheries. In this paper, we analyze the implications of...
Today fish is the most traded food commodity in the World. This situation is not without generating potential issues. On the one hand, fish trade is said to support economic growth processes in developing
countries by providing an important source of cash revenue. On the other hand, fish trade is...
In many situation, fishing activity adversely impacts the state of the marine ecosystem, impacts which feed back to affect fish stocks. Some ecosystems appear to have multiple equilibria and exhibit hysteresis, whereby they can become stuck in low productivity states. We show how adding ecosystem dynamics to a classic fisheries...
Since January 2008, the fishing agreements between the European Union and ACP (African, Caribbean, Pacific) countries have changed to comply with WTO rules and improve the management of the fisheries. However, the poor countries depend perhaps too heavily on foreign aids to impose any management system to the distant water...
Under open access regime, the coastal fisheries resources are overexploited in Vietnam. Recently, the community based fisheries co-management is becoming priority policy of Viet Nam, however, the government is confusing about how to approach it. The piloting approach by learning from previous and existing pilot community based fisheries management models...
The Mekong River Delta plays an essential role to Vietnam’s economy in terms of both rice and fish production. Annual flooding water and a rich level of aquatic resources strongly affect about 10 million
local people, as well as extend beyond the boundaries of wetland itself. Flooding water and wild...
This paper will address the effectiveness of fisheries co-management between the Ministry of Fisheries and Te Arawa a central north island indigenous tribe of Aotearoa/New Zealand. The Ministry of Fisheries, as the manager of fisheries resources, must provide a balance between the interests of all New Zealanders and the rights...
In 2001, New Zealand modified its quota management system (QMS) to function as a hybrid ITQ/tax system. Catches in excess of annual catch entitlements (ACE) incur payments, called “deemed values”. The deemed value
system was part of the reforms that separated ACE from quota, which reduced transactions costs for both...
Conflict between the recreational and commercial sectors in New Zealand is largely limited to the fishery within the Territorial Sea. Although most of New Zealand’s fisheries’ value comes from mid to deep water stocks outside the Territorial Sea, there are a number of commercially valuable inshore fisheries.
Traditionally, conflict between...
We estimated the economic rent obtained currently (that is, in 2002) in the Namibian hake fishery and the rent that might potentially be obtainable if the fishery were managed optimally in the sense of economics. We first reviewed previous economic and biological studies. We then used the theory and model...
In view of the coastal areas, vulnerability to natural hazards particularly tsunami, earthquakes, etc, are
rather increasing. The tsunami, giant tidal waves struck on 26th of December 2004 caused severe damage to people and their livelihood. It is now felt that the country should enforce a regulation procedure to manage...
For the past decades, around 20% of the natural coral reefs were lost and > 20% more is currently deteriorating. Due to the recognition of positive impact to fishery resources enhancement by artificial
reefs (ARs) deployment, Taiwanese government has started deploying ARs as a measure to improve the environment of...
When weak and strong fish stocks are caught in the same fishery, managing for the protection of the weak
stock may result in foregone economic benefits from harvest of the strong stock, while managing for the
strong stock may result in overfishing of the weak stock. A particular complication arises...
A key issue in fisheries restoration is the speed at which recovery can occur, while still meeting the
economic and social constraints which managers must deal with. This paper uses the viable control approach to examine fisheries restoration and study the tradeoffs involved with the selection of recovery strategies. We...
The Social Sciences Branch (SSB) of NOAA’s Northeast Fisheries Science Center (NEFSC) uses economic data to estimate the economic impacts of fisheries regulatory actions. Since 1995, the Northeast Fisheries Observer Program has collected trip cost information from commercial fishing vessels on which observers have been deployed. However, the allocation of...
It is widely accepted that in sea bottom areas where there is a scarcity of rocky formations and declining marine fish due to fisheries pressure, the deployment of artificial reefs (ARs) is a possible way to mitigate the problem. If ARs have an ecosystem-based fisheries management goal that means their...
