Abstract: This research aimed to explore the value chain of Black tiger shrimp in Cox’sbazar district, Bangladesh. Actors involved in the chain are farmers, wholesalers, commission agents and processors were interviewed by different questionnaires. A total sample size of 48 surveyed households were visited and analyzed for this research. Results showed a map of actors, costs and earnings, employment distribution, facilities and difficulties of each stage. Farmers, wholesalers, commission agents and processors are the four main actors which contributed directly to shrimp production and influenced the economical value. Others actors Hatchery, nursery, seed collector impacted indirectly to the shrimp production as well as value chain development. The micro level producer, farmers are in worst condition as their revenue and cost share are the highest and the profit share are the lowest against revenue and cost. Other three actors are in same position enjoying with positive profit. Processors did a critical job with some challenges to fulfill the demand of importers. To upgrade this chain, the actors specially the farmers should be trained up with scientific way, the corruption free environ should be established by government and micro level producers should be empowered to enjoy the perfect competitive market. In addition, wholesalers have to be facilitated with giving loan by government with easy term and conditions. URI: http://hdl.handle.net/10037/4863 File(s) in this item: 1

Abstract: Frog is valuable product in Vietnam but the natural frogs are overexploited thus, the new model to raising frog is desired. Many species of frogs are cultured in Vietnam, especially in Ho Chi Minh City, for trial of the adaptive ability of exotic species in Vietnam condition. Recently, the frogs’ species from Thailand and Taiwan are prepotent and spread out Vietnam. Nowadays, frog culture becomes one of the newest industries in Vietnam. With a short life cycle, frog culture is farming as economic efficiency for farmers to get return. However, being a new industry, it is quite hard to manage the supply chain of frog. Developed from 2000, this industry production has been growing up and down many times due to the spontaneous development of farmers. Recently, frog farming has new potential horizon to progress firmly. There are new potential partners from US, EU, Taiwan, etc cooperating with Vietnamese farmers for lasting cooperation. This study tries to apply the theory of value chain to analyse the activities of participants along the linkages of frog farming around Ho Chi Minh City. Moreover, the fluctuation of the final price of this product is the biggest problem of farmers. There are many farmers who have to quit this industry because of the fall of price. Of course, the output price is impacted by many internal and external factors thus I want to point out the causers of the inordinary change of price and suggest solution for that. Supply chain of frog in Ho Chi Minh City is made up by four main actors: The hatcheries, the frog farmers, the whole salers and the retailers. Most of frog farmers are small scale and they raise frog with other aquatic products. Besides, the supporters such as medication, feed suppliers, and processing factories also adhere this chain and build up the added value for the final products of frogs. However, frog processing is not developed in Vietnam thus the export volume of this product is limited. Most of frogs are supplied directly to the market for consumers. This study has represented the map of frog value chain in HCMC, analyzed the cost and benefit of frog based on the data of farmers’ budget and the transmission prices along the chain. The superprofit and low cost of frog culture attract many farmers join in frog industry but the risk of unstable price let them give up quickly. Hatchery farm achieves more than 100% profit from selling juvenile for farmers. The farmers can obtain a profit of 0% to 250% per kg of frog. The net profit of wholesaler and retailers are more stable. About 11% of the frog value is added by the wholesalers and17% value is added by retailers. This study is conducted mostly in Son Ca Farm, Hoc Mon Distreet. Data is collected from many sources, most of them are primary data surveyed by questionares.

Abstract: This study employs a hedonic price model to investigate the relationship between package prices of one-day island tours and the different attributes/characteristics associated with them. 127 observations of prices were obtained from 24 tour operators running in Nha Trang City. Using OLS regression method, the results show that the differences in prices among tours to a large degree can be explained by the differences in five various characteristics. Specifically, quality of lunch, the availability of VIP tour, the presence of seafood serving and diving activity have positive and significant effects on prices while the number of destinations has a negative significant effect on prices. With regard to the empirical estimates of attributes’ relative importance, quality of lunch is at the head of the ranking list. The results of this study are expected to assist business managers as well as policy makers in drawing strategies for the improvement and investment.

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: The research measure the profitability and technical efficiency of Black tiger shrimp farms and White leg shrimp farms in Song Cau district, Phu Yen province, Vietnam. Cross-sectional data of 62 Black tiger shrimp samples and 88 White leg shrimp samples were used for comparison two production systems. The profitability analysis shows that White leg shrimp farms achieved an average profit per hectare of 78,883,209 VND ($3,944.16), which was approximately 4 times as much as Black tiger shrimp farms. A nonparametric data envelopment analysis (DEA) approach reveals that the estimated mean technical efficiency of the Black tiger shrimp system under assumption of constant returns to scale, variable returns to scale and scale efficiency were measured to be 0.82, 0.95 and 0.87, respectively. In White leg shrimp system, the farms achieved a mean efficiency level of 0.88, 0.94 and 0.95 under condition of constant returns to scale, variable returns to scale and scale efficiency, respectively. The findings also show that there was positive correlated between profit and technical efficiency. URI: http://hdl.handle.net/10037/4770 File(s) in this item: 1
