Motivated by a real-world problem, we study a novel setting for budgeted optimization where the goal is to optimize an unknown function f(x) given a budget. In our setting, it is not practical to request samples of f(x) at precise input values due to the formidable cost of experimental setup...
A plant community classification was developed describing the comprehensive variation of oak vegetation currently occupying the Willamette Valley Ecoregion of western Oregon. Multivariate statistical analyses were used to classify field collected floristic and habitat data. Field sampling targeted minimally managed, homogenous vegetation stands with a significant oak component occupying 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...
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...
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,...
Climate change may cause significant changes in the distribution, abundance, and species mix of commercial fishery resources. In any given area stocks of some species may decline; stocks of other species may increase; and new species may appear in commercially significant volumes. However, it is difficult to predict what specific...
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...

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...
During process of seeking methods of advanced fishery management experience to apply into small-scale fishery in Thua Thien Hue – Viet Nam, the author is surprised that some advanced countries also apply similar methods that the traditional fishing village associations (Van Chai) has been managed fishery activities in lagoons in...
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...
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...
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...
Fishery villages (Van Chai) has been formed for about 300 years since pioneered fishers settled in Phan Thiet for their livelihoods. This was a original social professional organization found before official administrative system established.
Binh Thuan has more than 30 Van Chai in coastal areas, in which about 20 importantly...
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 sustainable yield function is a favoured tool in fisheries policy making. Normally, this function is drawn as a continuous curve in effort-yield space. This means that sustainable yield (harvest) is gradually reduced to zero as fishing effort increases. This, however, does not have to be the case. The sustainable...
The majority of monitored fish stocks globally is fully or over exploited, that is, at or below their maximum sustainable yield stock levels. Despite this resource situation international trade in fish products have been increasing for a long time. An export tax on fish and fish products, as an alternative...
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...
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...
According to conventional economic wisdom the economically more efficient technology will always outcompete the less efficient. This hypothesis has usually been taken to hold for the exploitation of common pool renewable natural resources such as fish stocks. This paper claims that, while this is not necessarily false, it may be...
Main fishing gear in Thailand was otter board trawls. More than 70% of the total Thai fishing vessels had been using this fishing gear, as well as push net which was restricted targeting for demersal resources. Due to the 2.5 cm fine mesh size, juvenile economic species had been caught...

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...
This paper provides an overview of ongoing work undertaken in Senegal to understand the implications of fisheries certification on the octopus value-chain. It analyses the opportunities to increase social and
economic benefits for poorer groups and to establish a more gender sensitive approach to eco labelling through the implementation of...
There is now an increasing demand among consumers for high-quality and safe aquaculture products. However, in becoming an important contributor to the markets for seafood, the aquaculture industry has become increasingly subject to rigid food safety, traceability, and processing requirements (e.g. Hazard Analysis and Critical Control Point (HACCP), Good Aquaculture...
Some recent studies have shown the outstanding price linkages at the global scale between the cannery-grade
tuna markets over the last decade. When it comes to price transmission along the European value chains, opposite results between the two major species (skipjack and yellowfin) are found: the market for final goods...
As compared to other countries, France has been involved very lately in the discussion about fisheries ecolabelling. Reluctant to adopt the existing ecolabels, the professional organisations, the Ministry of
food, agriculture and fisheries and the European Commission itself tend to create their own label guidelines to take into consideration other...
Our paper aims to study the image of the European fisheries sector, as perceived by European citizens. To
our knowledge, no approach has focused on the perceived impact of fishing on the halieutic resources. More precisely, we seek to analyze the perceived impact on the marine environment of fishing activities...

This paper is focussed upon the marketing implications and adoption responses from a 3 years multidisciplinary Research Councils UK project which has examined the prospects for UK (agricultural) farmers to diversify into production of warm-water tilapia. The proposed production process and product characteristics abound with green credentials, consistent with emergent...
The Byrd Amendment permits US firms that petition successfully for antidumping duties to collect tariff revenues. Whether these payments strengthen the duty’s ability to raise price depends crucially on market structure. In a competitive market where domestic and imported goods are imperfect substitutes, the payments are akin to a production...
The processing industry is playing an increasingly important role in Vietnam’s overall economy. A study on the restructure in this sector across the Coastal Central South has demonstrated the dominating part that middlemen are taking in connecting the supply, represented by fishers and farmers, to demand, represented by processing enterprises....
