Abstract: The establishment of the Nha Trang Bay Marine Protected Area (NTB-MPA) in the Southern coastal of Central Vietnam in 2002 focused on two main purposes: to reserve and manage the biodiversity environment within the MPA areas; and, to enhance the local communities’ life-conditions by providing the alternative livelihoods. To assess the efficiency of an MPA management process, it needs the understandings in what extent and how the perception from stakeholders about the goals of the MPA establishment and management process was. Much has regarded such perceptions with the complication. This study provides an example in analyzing the stakeholders’ opinions of the MPA goals through the performance indicators by applying Analytic Hierarchy Process (AHP). The options from stakeholders were investigated by the mean of a pairwise comparison survey. The results show that by all stakeholders, there was a little homogeneity in weighting the priority of the NTB-MPA objectives in improving the local communities’ livelihood. The objectives of the NTB-MPA management process in preserving the biological resources receive the quite similar opinions from all stakeholders in ranking their priority. The other conclusion is about the failures in enforcing the regulation of “banning trawlers in the water within and around NTB-MPA” together with the great requirements for enhancing the available sources of information about the MPA. The major challenge for NTB-MPA management process was the possible conflicts between the groups of stakeholders, which were more popular than those among individuals from each separate group of stakeholders regarded as within-conflicts. Especially, the within-conflicts appear mostly amongst 2 key stakeholders: fishermen and local households. Key words: AHP, Multi-criteria analysis, Stakeholder, Performance indicator, NTB-MPA.

Abstract: Since the 1990s, Vietnam’s government has made great efforts to develop the offshore fisheries development program. Study on the economic efficiency of the offshore long-line fishery is needed to evaluate and improve the program’s effectiveness. This thesis presents findings based on survey data collected through a representative sample of 37 registered offshore vessels operating in the Vietnam’s Exclusive Economic Zone and in the international waters. The empirical results show that excluding the government fuel subsidy, the owner of an average long-liner earns a profit of 63.363 million VND - equivalent to profit margin of 7.5% and return on investment of 16.0%. With subsidies, profits increased to 93.111 million VND and the two corresponding economic ratios also went up to 10.6% and 23.5%, respectively. This paper also discovered that the fishery in 2008 was less economically efficient than in 2004. However, the average monthly crew share is 1.8 million VND, higher than the average income per labor working in the gill net fishery in Khanh Hoa Province. A closer inspection of the economic data reveals that direct subsidy to compensate partly for fuel costs increase affected the overall fishery. Furthermore, this study provides evidence to support why an average longliner is still able to generate profits in the open access regime if vessels can capture more cost efficiency while the average revenue of relative standardised effort for all vessels is the same. Finally, this study also demonstrates, the surprising result, that the vessel group with the biggest engines, larger than 150 hp, are least cost efficient, whereas the vessels with the smallest engines, less than 90 HP, are most cost efficient and have the highest return on investment.

Abstract: This research applied value chain analysis to represent activities of participants and their linkages in Black tiger shrimp culture industry in Hoa Binh district, Bac Lieu province, Vietnam. Actors involved in shrimp farming practice from farmers, collectors, wholesalers, feed and veterinary medicine enterprises, processors, to hatcheries, and nurseries were interviewed by separate questionnaires. A total sample size of 71 surveyed households were conducted and analyzed for this research. Results presented a map of actors, costs and margins, employment distribution, advantages and disadvantages of each level. Farmers, collectors, wholesalers and processing companies are four main actors which contributed directly to shrimp production and effected to the commercial value, and shrimp price. Hatcheries, nurseries, feed and veterinary medicines enterprises impacted indirectly to the economic efficiency and the value chain development orientation. Especially, small-scale farmers are the weakest and the most vulnerable actor in the value chain. The processing companies increase added value about 18%-26% and get the opportunities and benefits from trade better other actors. To upgrade this chain, shrimp farming clubs or farmers’ associations should be established in this district. They need to link to other actors with contract systems to meet the market demands and ensure sustainable development of shrimp industry. URI: http://hdl.handle.net/10037/3773 File(s) in this item: 1

Abstract: The open access fisheries regime has led to the degradation of marine resources and to conflicts in sharing them and the fishing grounds in Tam Giang Cau Hai lagoon in Thua Thien Hue, Vietnam. In 2003, community-based fisheries management (CBFM), particularly through Fisheries Associations (FA), was introduced and established. As of 2011, there were 62 local FAs. It means that local FAs have played an important role in the implementation of CBFM and as a major partner of the Government in protection of aquatic resource and fisheries management. This master thesis is based on primary data collected through a questionnaire survey and interviews of key informants. In addition, secondary data and literature on Co-management, fisheries management and transaction-costs were used to supplement missing parts. This study highlights the demands of implementation, level of awareness and participation, effectiveness and weakness and methods for measuring the transaction costs in Giang Xuan FA in particular and fisheries Co-management system in general.

Abstract: Fish is the main source of animal protein in Bangladesh. However, no previous studies I am aware of has analyzed or explored consumption and attitude toward fish in Bangladesh. In accordance with several studies in the area of food consumption behavior, this study use the Theory of Planed Behavior (TPB - Ajzen, 1991) a conceptual framework to explore the consumers attitude and consumption of fish in Dhaka city. Attitude, subjective norms, perceived behavioral control in the traditional theory is extended with perceived risk, trust and knowledge in order to explain intention and consumption of fish. The measures used to evaluate the constructs in the theories are adopted from previous studies. The study employs the methods of descriptive analysis, test of reliability and means difference, factor analysis, and multiple regression analysis to analyze the data collected in Dhaka city. The results show that fish as a meal is a common and broadly used food, and the people have high motivation and positive attitude toward consumption of fish. Perceived quality is revealed as the main determinant of consumers’ attitude, while availability is the main determinant of perceived behavioral control. Bones and smells of fish are not considered as unpleasant and not found as a significant indicator of attitudes. Time consumed to cook and prepare fish also did not found as a significant indicator of perceived control. It is also found people knew that fish are cultured in toxic environment and preserved with hazardous chemical, however the risk perception is less significant. This study found that people have much trust on food information from specialist like doctors and university scientist; but have low trust on Government and political parties. In the area of theory testing this study found attitude and norms are good predictors of intention, while intention and attitude have good predictability on consumption behavior. PBC did not find having effect on both intention and behavior. The cumulative variance explained by the data set is 73% for the constructs of TPB. In case of the extended model it is observed that intention, attitude, trust on information sources and product knowledge have significant effect on behavior, while attitude, norms and procedural knowledge is revealed as good predictor of intention. In the extended model it is also observed that there is no statistically significant relationship between risk, worry, trust on information sources, trust on sales outs with intention and behavior. However, while regressing intention with perceived risk (risk and worry) and trust (trust on information sources and on sales outlets) this study found statistically significant relationship. Key words: TPB, perceived risk, trust, knowledge, fish consumption, attitude, and intention URI: http://hdl.handle.net/10037/2472 File(s) in this item: 1

Abstract: Vulnerability leads to poverty; poverty leads to vulnerability, a controversial two concepts without an end nor a start. From recent past, poverty has been addressed in terms of vulnerability. There, the possible ways to be vulnerable is stressed to investigate. Risks, shocks, and uncertainty have been identified as the profound sources of vulnerability so as to poverty. In fact, the study was designed to assess the coping mechanisms of vulnerability that are adapting to hammer the idiosyncratic risks and shocks in the small-scale fishing community in Southern Sri Lanka. Stratified random technique was applied to draw a sample of three groups representing, NMRT owners, FRP owners, and crew members. Totally 50 households were selected. Both panel data and a cross sectional survey was carried out to glean the data. The results highlight a clear variation of fishing income between season and off-season for the whole three groups. The FRP owners’, main cash inflows are fishing income, drawings, gifts, bank loans, and co-operatives irrespective of the season. Zero income, harsh sea condition, and inability to secure operational expenses knock their livelihoods frequently. Individuals are adapting memberships in formal organizations, accumulation of wealth, activity diversification, migration, and social networks as ex-ante risk coping strategies. Loans from friends, mortgage, withdrawals from banks, and intra- community transfers are the ex-post risk coping strategies. The safety net arrangements are vital to ensure the mutual insurance among the small–scale fishers. The importance of a high heterogeneity within a network is elaborated by the income- expenditure, and saving patterns of the groups. URI: http://hdl.handle.net/10037/1980 File(s) in this item: 1

Abstract: Humans are getting more dependent on marine and coastal resources. This has led to increased fishery exploitation and in many cases overexploitation with habitat degradation. This threatens coastal and marine resources all over the world. The current management approaches have failed to control fishing capacity and conflict in sharing fisheries resources due to population growth, poverty and a lack of awareness raising. The management and governance of small-scale fisheries is ready for worldwide reform. In recent years, Marine protected areas (MPAs) are becoming a popular tool for management and conservation of marine resources. Co-management is a recommendation as a solution of governance for marine protected areas. Co-management is a process that involves democratization and decentralization mechanisms through collaboration and power-sharing between resource users and government officials (Pomeroy and Rivera-Guieb, 2006) This paper highlights the co-management of an MPA in Trao Reef locally managed marine reserve, which was established in 2001 to protect and rehabilitate fisheries resources in general and the coral reef in particular. In addition, this paper demonstrates one way to approach co-management which include the transaction-costs, the method for measuring the transaction costs in fisheries co-management system. Transaction costs are defined as “the cost of transacting, which consists of the costs of measuring the valuable attributes of what is being exchanged and the costs of protecting rights and policing and enforcing agreements” (North 1990). The study is based on fisheries management, co-management, transaction-cost literature and secondary and primary data. The reduction of transaction-costs in the last stage of co-management regime is used to choose alternative institutional arrangements for managing a fishery for public policy decisions. This study is also the first paper to mention transaction-costs in fisheries co-management in Viet Nam. URI: http://hdl.handle.net/10037/2537 File(s) in this item: 1

Abstract: Three different types of culture and conditions were tested to determine the profitability of Rural and Artisanal Aquaculture Project in Ecuador: monoculture of the freshwater fish named locally cachama (Piaractus brachypomus), monoculture of red claw crayfish (Cherax quadricarinatus) and polyculture tilapia (Oreochromis sp.) – cachama (Piaractus brachypomus). The economic models used for this particular analysis were Net Present Value (NPV) and Internal Rate of Return (IRR). Using these methods in combination with a sensitivity analysis foresaw the feasibility on investment for the monoculture of red claw crayfish (Cherax quadricarinatus) showing a Net Present Value (NPV) of 11,458.80 USD, which was the highest among the trials, at 8.65% real interest rate and Internal Rate of Return 44%, followed by the monoculture of cachama (Piaractus brachypomus) with NPV of 10,130.82 USD at the same discount rate and IRR 35%, respectively. The third place in order of profitability goes for the polyculture tilapia (Oreochromis sp.) and cachama (Piaractus brachypomus) with NPV of 1,888.99 USD and 8.65% real interest rate. The IRR percentage registered on the last type of culture was 19%, being the lowest among the three types of production analyzed. Among the conditions tested in the sensitivity analysis, there were: the sudden increase in discount rate, 10% increase in costs, 10% decrease in benefits, simultaneous 10% increase in cost and 10% decrease in benefits, 10% increase in feed cost, 10% increase in price of fingerlings and larvae and reduction in survival rate to 73%, 50, 25.1% with 80% as optimal. On this sensitivity analysis, the monoculture of red claw crayfish (Cherax quadricarinatus) overcame most of the conditions tested being defeated by the reduction in survival rate in the order of 50 and 25.1% which NPVs turned out to be negative; -7,429.60 USD and -22,004.70 USD, respectively. On this case the IRR was indefinable. Nevertheless, still some speculations about certain conditions such as broad experience in the Aquaculture field and technological advantage might be serious factors to be considered at the moment to select this investment and they must be analyzed carefully.

Abstract: In Vietnam, marine cage lobster aquaculture has been expanding significantly over the last years. Besides the economic contribution for locals living in the coastal areas in Central of Vietnam, this industry has created some problems that are relating to the marine environmental protection where trash fish feed is predominant. This paper investigates the environmental impact on cage marine lobster aquaculture in Vietnam by using the Change of Productivity method in which nitrogen releasing from lobster cage is considered as the seawater quality parameter. And the usage of a mathematics function in this study is Mass Balance Model to calculate the total nitrogen loading volume in an every single crop in three provinces. This approach indicates the reverse relationship between lobster productivity (kg/m2) and volume of nitrogen releasing in a household unit. Additionally, the lobster productivity diminishes gradually if the number of cages increases in specific area. On the other hand, the estimation of the environmental effect uses the ‘Treatment Cost’ calculation for this waste has been done. However, this figure is lower than comparing that of the Change of Productivity method without considering the environmental carrying capacity. To give a strong recommendation to both local authorities, marine environmental management Departments and policy makers having a better consideration to the environmental and economic balance, the analysis of Cost – Benefit is presented in this study. This analysis shows that marine lobster aquaculture industry in Vietnam is profitable. However, because there is yet marine lobster food processing industry, the lack of awareness in environmental conservation from lobster farmers as well as the open-access sea in Vietnam that have been generating increasingly the marine water pollution. Therefore, in order to have a sustainability in cage marine lobster aquaculture development in Vietnam, it is vital for the local authorities and any other organizations to promote the development of high quality feed from food industry, to have technical training programs and raise up the awareness of the community in environmental protection as well as to plan strategic schemes to the entire region especially in the farming areas. Finally, setting up the environmental protection regulations to whose responsibility in a certain sea area is essential task to the government.

Abstract: A field study on the economic performance indicators for coastal fisheries are needed in order to implement fisheries policy in Khanh Hoa as well as in Vietnam. The research project “Economic performance indicators for coastal fisheries - the case of pure-seining in Khanh Hoa” established to fulfill these demands. A questionnaire about technical characteristics and economic data is used for data collection through interviews with vessel owners. This paper presents preliminary findings for 100 purse seiners, representing 10% of the total population, in Nha Trang and Cam Ranh (Khanh Hoa province) in the group of vessels with engine power of less than 90 HP. The following indicators are presented: gross revenue, gross value added, gross cash flow, net profit and crew share. The results show that the coastal purse seine fishery in Cam Ranh is more profitable than in Nha Trang for each engine power group. The owner of an average purse seiner of all groups of horse power in both locations of Nha Trang and Cam Ranh is not only capable paying for all expenses, but also has a reward for the operating year. The boat owner of an average vessel in the group of horse power of 75 -< 90 Hp has the highest values of annual gross cash flow and net profit following location. Thus, the annual average of crew shares for this group of horse power was quite high. It was almost 2.0 times more than the average earnings of labor in the whole country. The boat owners of the engine power group of < 20Hp and 20-<45Hp have lowest values of annual vessel gross cash flow and net profit following location. Thus, the annual average of crew shares for those groups of horse power is quite low. They are almost 1.2 times more than the average earnings of labor in the whole country. Regression analysis of gross revenue using technical characteristics as independent variables is performed, and the results are demonstrated. The technical factors that impact on the gross revenue are the length of net, fishing experience of skipper and location. These are significant factors impacting on the gross revenue. Further work will include collection of more data, which will be analyzed with stronger techniques for in depth analysis such as Data Envelopment Analysis (DEA) or Stochastic Production Frontier (SPF).

Abstract: The initial results of this study demonstrated that the offshore gillnets fleets in the Central of Vietnam can get high economic efficiency, an offshore gillnet vessel make a margin profit of 10%, the annual income of vessel can reach 51% of gross revenue. The average annual income of a fishing man is much higher than the average personal income on the national scale, corresponding to 156% in 2007. The offshore gillnet fishery could be attracted labour as well as investment in the future. The analysis has demonstrated that a gillnet vessel in the group of vessels with main engine power upper than 90hp has higher annual gross revenue, income, and net profit than the rest group. Impacts of engine power and hull length have also significant for vessel group with smaller 90hp engine power. For improving on economic performance, it is necessary to encourage owners of vessels in group smaller 90hp take more investment to improve vessel’s engine as well as hull length. For gillnet vessels in group of larger 90hp, the owners should not concentrate on engine power, the hull length need to be maximized correlative with the current engine capacity, the total gillnets length should be increased. The limitations of this study include a quite small sample because of the data collection is very difficult and costly in the current Vietnam’s conditions. The sample does not cover some important indicators such as the marine resources, the changing in market prices of inputs or outputs of the used models, and social-economic indicators (management ability, skipper and crew skills, education and average age of fishing men, and so on).

Abstract: Trao Reef Locally Managed Marine Reserve was established in 2001 to protect coral reef being under threat because of human activities. However, the economic value of coral reef represents an important sight to help local people and resource managers in using and managing the resource effectively in the marine reserve has not been seen. By using financial analysis to calculate producer surplus of resource users, this study evaluated the direct use value consisting of fishery and aquaculture values of coral reef in the marine reserve. The findings show that the direct use value of coral reef is US$ 207,819 in which aquaculture is an important contribution. This study also investigated the evaluation of effectiveness of the marine reserve management under the context of community based management approach by contrasting with Nha Trang Bay MPA management which follows top-down management approach. The results show that community in Trao Reef marine has higher awareness, higher compliance, and higher participation to the marine reserve management. These indicators imply that Trao Reef management is performing better than Nha Trang Bay MPA management. URI: http://hdl.handle.net/10037/1983 File(s) in this item: 1

Abstract: In the past ten years, China has developed to be one of the most important countries of fishery production field. Annually Chinese fishery products is increasing . In 2009 the total fishery production is 50.4 million tones.(China statistical reports,2009) As the same rate as the increase economy, the sharply development of fishery production is also remarkable. But there are serious problems behind the promising surface. The conflicts between the economic development and ecological and environmental declaration are becoming prominent. The most serious situation is in Yangtze River basin. According to a Chinese governmental report, the total annul aquatic production in Yangtze River is about 20% of total national fishery production. But from the latest 20 years, the fishery biomass situation is continue damaging. How to fix Yangtze River ecosystem is the top priority in fishery management. And how to deal with the fishery of Yangtze River is also the main problem of Chinese freshwater industry. Chinese government has authorized many measures and policies in the last 10 years, but the situation became even worse during this period. Because of the historical and political reasons. Chinese academic levels in fishery economics and management is limited, and the fisheries research is not given enough priority. There is hardly any effective research on Yangtze River fishery resources today. At a global level , a new term is becoming quite popular, within the field of fishery management namely ecosystem-based fishery management. Many foreign countries has implemented this theory into practice and also FAO support this theory as the most important management theory in fishery in the future.(FAO, 2005) The same as many other new theories, there are so many disputes and controversies on this theory. Problems often pointed at are shortage of data and poor knowledge, the theory is still not fully developed. Based on the investigation of the formal management failure in China. We figure out that may be the ecosystem-based fishery management can save the environment and fishery resources in Yangtze River. We are going to analysis the main principles, goals and policies for the fishery management, which is the original in Yangtze River academic research. Good theory needs to be tested by facts. Based on the theory of EBFM in Yangtze River, we chose a small island in Yangtze River to implement the theory . According to the local conditions and new development perspective, we chose Jiangxin island of Nanjing as a research field. We gave management advices for this island and hope it can be a good example that balance the environment profit and economic benefit. This paper will be a operation advices give to the development company of Jiangxin island for the implementation of ecosystem based fishery management on that island.

Abstract: Planning, implementing and managing MPA not only requires attentions to biological issues which influence the performance of MPA but also to social and economic aspects that can greatly affect the outcome of MPA implementation. This study used data from logbook program over 4 years and face-to-face interview to explore the effectiveness of Cu Lao Cham MPA which is one of 4 MPAs in Vietnam through the performance of ecological (CPUE), economic (income from fishing) and social (perception to the MPA objectives) indicators. Result of study has indicated linkages between ecological, socio and economic issues which often give an insight to direct and immediate feedbacks to MPA and despite the various of problems in management of Cu Lao Cham MPA such as poaching, poor and ineffective enforcement, sustainability…., the performance of ecological, economic and social indicators in this study showed that Cu Lao Cham MPA has achieved a significant amount of success and is one of the few well-managed marine protected areas in Vietnam. This study has also identified a number of indications that the coastal fishery of Cu Lao Cham could be on a transition towards becoming a viable, sustainable characteristic of better-established tropical marine protected areas.

Abstract: Since 1997, development of white leg shrimp farming in Vietnam has attracted considerable attention due to its high export potential. Therefore, it is now necessary to assess the annual efficiency performance of white leg shrimp farms in order to improve Vietnam’s aquaculture policy. This paper based on a character sample of 61 white leg shrimp farmers in Khanh Hoa province, representing about 13.2% of such farmers in Khanh Hoa, Vietnam. Using an output-oriented VRS Data Envelopment Analysis, the standard efficiency was measured and then regressed to the farmer characteristics and production environment to identify the determinants of technical efficiency for those farms. The empirical results suggest that socio-economic factors such as education and experience are positively related and experience more significance than education, to the efficiency of white leg shrimp farmers. Some environmental factors, such as more distance from a channel, imply worse results for efficiency in white leg shrimp production. Financial factors, such as the proportion of total costs relative to total income, the proportion of variable costs relative to fixed costs, sales margin and return on asset have a positive effect on efficiency of the farmers. In addition, comparing the technical efficiency results of planned farms and unplanned farms, groups near to the channel and far from the channel, farmers who have a water keeping pond and those who do not have a water keeping pond, it was seen that the unplanned, far from the channel, and non-water keeping pond farms were less efficient than their counterparts. Therefore, this study suggests that there is a strong incentive for planned aquaculture. As it was seen that water sufficiency is necessary for efficient farming, additionally, it is better for a farm to be near the channel. If, however, it is far from the channel, a water keeping pond without culture is recommended. Moreover, having more experience in a cultured system was also suggested as a way to have the desired increase in productivity. Finally, further study about congestion problems, which have not been dealt with in this study, is recommended. URI: http://hdl.handle.net/10037/2518 File(s) in this item: 1

Abstract: Although Nui Chua National Park MPA is considered as an effective MPA of Vietnam, especially in the involvement of community in management process, an overall assessment of biodiversity, socioeconomic and governance could help managers continue developing the advantages and overcome mistakes. By using relevant indicators, this study stated that abundance of species is somewhat increased, the conservation objective of Nui Chua MPA has been achieved. The livelihood of local communities slightly improved and the tourism provides some alternative livelihoods for households around the MPA. In addition, there is a small reduction in the dependence of fishermen on marine resources due to the rising profits of vessel affected by Nui Chua MPA. Community plays an important role in decision making, monitoring and enforcement in the MPA management. However, the law, policy and responsibilities of stakeholders have been not clear and little support for community’s activities. Those results explain for the necessary of the change and improvement of the management in Nui Chua MPA in future to be more successful. URI: http://hdl.handle.net/10037/4751 File(s) in this item: 1

Abstract: The primary purpose of this study to understand how the consideration set size affect for consumption frequency of fish in Sri-Lanka. Consideration set size of fish is considered to be affected by consumer attitude, convenience orientation, and consumer knowledge in Sri-Lankan context. Thus, the second objective was to investigate how consumer attitude, knowledge, convenience orientation, variety seeking tendency and price consciousness affect the formation of consideration set size. Based on that, it aimed to suggest a marketing strategy implication for food marketers, in addition with strategy implication for increasing fish consumption. The proposed conceptual frame work was used to achieve the objectives in this study. Thus, the proposed model consisted with the constructs of attitude, knowledge, convenience orientation, variety seeking tendency and price consciousness. This thesis was an extension of Rortveit and Olsen (2007: 2009) study with the inclusion of additional antecedents of variety seeking tendency and price consciousness. The questionnaire survey was carried out in Galle district in Sri-Lanka with the convenience sample of 250 respondents. The measurement scales used here were adopted from previous studies found in literature. The confirmatory factor analysis and structural equation modeling in Amos 16.0 were used as statistical analysis tool. It was found that significant positive relationship between consideration set size and fish consumption frequency as a main hypothesis. Further, this study has found significant positive relationships between knowledge and consideration set size, between variety seeking related to personality and variety seeking related to food and between convenience orientation and consideration set size, while having insignificant relationships between knowledge and fish consumption frequency, and between variety seeking related to food and consideration set size. Surprisingly, attitude has an insignificant effect on both consideration set size and the consumption frequency of food. The main reason for this problem is skewneess of the data set. The study found that that belief of sensory aspects, health and convenience were significant predictors of attitude toward fish. Further this study revealed that price consciousness related to food has a negative significant impact on consideration set size. These findings indicated that from a marketing point of view, being chosen is effected by the size of the consideration set size, food marketers should advocate that consumers consider many kind of fish products in choice occasion. As shown by the study, set size can be increased through the consumer knowledge variable. In such a condition, manufacturer must tend to put in to consumer education which will lead to have a positive impact on consideration set size. From the theoretical point of view, this research contributed to fill the gap in the consumer consideration literature in general, but also to the literature trying to explain fish consumption in Sri-Lanka. A limitation of this study is that the relationship between the consideration set size and the consumption was only tested for the size dimension of the consideration set. Further more, sample is relatively small and they are not statistically representative to the total population in Galle district or Sri-Lanka. Therefore, the results could not be generalized to Sri-Lanka. Keywords: Consideration set size, attitude, convenience orientation, knowledge, and variety seeking tendency and price consciousness, fish consumption, Sri-Lanka.

Abstract: The first purpose of the thesis is to find how visitors evaluate the quality of different facets or attributes of a destination image of Nha Trang, how satisfied they are with Nha Trang, loyalty intention to revisit and willingness to recommend Nha Trang to others. The second is to investigate what “image” is most important to explain global satisfaction with visiting Nha Trang. The third is to investigate how perceived quality, satisfaction and other motivational or dismotivational factors (e.g., demographic characteristics, variety seeking) influence loyalty intention to revisit and willingness to recommend to others. The survey was conducted in Nha Trang, Vietnam, with sample of 201 respondents.

Abstract: Over the past decade, China has developed to be the fastest growth market of consumption of Norwegian Salmon in Asia. In addition, Beijing that is the capital of China with over 15 million populations provides great demand in seafood consumption. Understanding consumer’s attitude is the first step to explain the consumption. Meanwhile, some factors (e.g. norms, availability, and knowledge) have been confirmed to influence on the consumption. Therefore, the study applies the theory of planed behavior (TPB) model to explain the consumption of Norwegian Salmon in Beijing. Moreover, the TPB model, which includes four components of consumer’s attitude, subjective norms, perceived behavior control, and intention, has been successfully used in several contexts, including seafood consumption.
