  Abstract:

  The research aimed to explore the value chain of frozen white leg shrimp exported to the U.S market from Khanh Hoa province, Vietnam. Three objectives were set up, that is, (1) to identify the activities conducted by different actors in the value chain and the corresponding costs and earnings of those activities, (2) to evaluate the distributions of revenue, cost and profit along the chain, and (3) to determine factors preventing shrimp farmers from dealing directly with processing firms. Research findings showed that before exported to the U.S market, white leg shrimp has to undergo farming, procurement, and processing. Shrimp farming basically comprises of such steps as pond cleaning, seed release, and caring. When shrimp attain harvestable size, middlemen come to perform the procurement which includes harvesting, preserving, and transporting. At the processing plants, shrimp are transformed into final products, packed, labeled preserved and stored waiting to be exported. During shrimp farming, farmers incur several costs like seed, feed, labor, and other miscellaneous expenses. At the procurement stage, addition to purchasing shrimp from farmers, middlemen have to add some other costs like transport, labor, ice, and other inputs to transfer shrimp to the next stage. At the processing stage, direct material, direct labor, overhead, and other costs are added in accordance with the accounting format. Farmers, middlemen and processors experience positive profit in the 2008-2010 period. Based on costs and earnings data, some calculations were made which revealed the distributions of revenue (export price), cost and profit of 1 kg frozen shrimp exported to the U.S market. Costs and profits distributions were in sync with expectations. The surveys revealed 3 reasons why farmers depend on middlemen to sell their harvest, that is, lack of facilities, delayed payment policy and risk aversion.

  Abstract:

  Dry fish is the low-cost dietary protein source in Bangladesh. As far the concern of the researcher, this study is the first of its kind to explore the dry fish consumption behaviour in Bangladesh. The general purpose of this study is to apply the general framework of the Theory of Planned Behaviour (TPB), explain attitudes, intention and dry fish consumption in Chittagong city and to extend the traditional TPB-model with some additional variables; perceived risk, knowledge, price and cost. The field experiments were performed in Chittagong city, Bangladesh with convenience sample of 208 respondents. The measurement scales used in this study were selected or adapted from previous studies. The study employs the methods of factor analysis, test of reliability, principal component analysis and multiple regression analysis to analyze the data. The findings showed that attitude, norms and procedural knowledge emerge as the key determinants of intention, while intention, attitude, norms and perceived risk effect on the consumption frequency. PBC, price and cost had no significant effect on intention and dry fish consumption. Perceived quality is found as the most important attribute to forming consumers’ attitude towards dry fish consumption. The proposed TPB and the extended model both of them fit well with the data and proved the expectations of this study in a promising way. The study found that people are more concerned about potential long-term risk to their family and others. Therefore, management attention should focus on reducing risks with which consumers may be faced through producing safe and hazard free dry fish. A communication strategy should focus much more on improving procedural knowledge and signing food safety for consumers with lower knowledge than the others. Key words: TPB, perceived risk, knowledge, price and cost, dry fish consumption, attitude and intention, Bangladesh.

  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:

  Since the 1990’s development of industrial trawl fisheries of Bay of Bengal, Bangladesh has attracted due to its high demand and abundance of fish and shrimp resources. This paper investigates Bangladeshi industrial trawl fishery by employing a bioeconomic model and an input-oriented Data Envelopment Analysis. The fundamental objective of this paper is to provide the technique through which long run sustainability can reach an optimum utilization of the resource efficiently to protect marine biodiversity and regenerate fish stocks. For this purpose, a conventional economic model is used simultaneously with a biological population growth model to develop a bioeconomic model. In order to achieve optimal steady state solutions, i.e., optimum levels of stock, harvest and effort are determined and efficiency is compared for five years. This study demonstrates that engine power, and fishing experience strongly affect technical efficiency. Results show that the Bangladesh trawl fishery is not managed and operated optimally and efficiently. Present situation of high effort level, less harvest amount and less fish stock signifies that the danger of depletion of the resource cannot be excluded . Finally, the study will propose some fishery strategies for Bangladesh, such as banning the inefficient trawlers to protect the resource.

  Abstract:

  To develop effective capacity management programs, it is significant to evaluate and control the fishing capacity and its utilization in order to reduce overcapacity and excess capacity and create a stable development of marine resources. This study estimate fishing capacity and capacity utilization (CU) for the multi-species small- scale trawlers in Nha Trang, Vietnam. Data were collected through a survey of 65 small-scale trawler owners in two years 2005 and 2006. Using a mathematical programming approach - data envelopment analysis (DEA), the results from this study show that most of vessels in Nha Trang were operating at less than their full capacity and there was excess capacity in the trawl fleet. Based on these findings, some policy implications for trawl fishery management in Nha Trang are also provided and discussed. .
