The ecological and economic value of cold-water coral ecosystems

Foley, Naomi; Armstrong, Claire W. (Journal article; Tidsskriftartikkel, 2010)

[+]

[-]

Abstract:

Despite the growing scientific literature on cold-water corals (CWC) there appears to be no studies that address the economic values or economic management of the resource. This paper presents an overview of the goods and services of CWC and their associated biodiversity. Use and non-use values associated with CWC are presented, and the methods relevant for assessing their valuation are discussed. The impact of human induced disturbance on CWC is reviewed, in order to indicate how knowledge of CWC values can be used by policy makers in the management of CWC as a habitat and vehicle for biodiversity.

Breaking through barriers to Norwegian fresh salmon trade with China by a new production technology

Luan, Lan (Master thesis; Mastergradsoppgave, 28-Dec-2011)

Abstract:

Atlantic salmon export plays an important role in the total Norwegian seafood export. EU countries are currently the main markets for Norwegian salmon export. China is one of the countries which are expected to have an increased demand for Norwegian salmon. Norwegian fresh salmon exporters are currently facing the trade barriers with respect to new inspection regime and high transportation costs when they export fresh salmon to China. This study is investigating whether Coolnova salmon, fresh frozen salmon using proton magnetic freezing technology, may break the trade barriers of Norwegian fresh salmon export to Mainland China. Firstly is the meaning of preferred fresh quality of Norwegian Atlantic salmon and secondly is the potential market value of the Coolnova salmon for the wholesalers and the supermarket in Hong Kong estimated. A sample of fresh chilled, Coolnova and frozen salmon fillets were tested by wholesalers and supermarket managers who gave their quality judgement recorded in a questionnaire. Different perceptions and attitudes were expressed related to both quality factors like fatness and colour influenced by the different fish feeding, sizes and fillet cuts of the tested salmon samples as well as factors related to the application of novel freezing and thawing technologies where Coolnova salmon has its advantage. The results show that freshness is a preferred product attribute of salmon characterized by appearance as a distinctive orange colour, clear white oil lines and a hard texture and smooth and juicy taste. The results indicate that Coolnova salmon after fresh-frozen and thawed, may satisfy the markets requirements for freshness and furthermore gain a cost advantage by the opportunity to move distribution from an expensive fresh airfreight to a low cost frozen sea freight. Frozen salmon can be kept in freezers for a long time without quality degradation and would thereby not be affected by the new quality inspection regime which hampers the fresh fish import to China. Coolnova salmon can thus break the trade barrier of Norwegian fresh quality salmon imposed by the Chinese government.

The evolution of the “harvest machinery” : why capture capacity has continued to expand in Norwegian fisheries

Johnsen, Jahn Petter (Journal article; Tidsskriftartikkel; Peer reviewed, 2005)

[+]

[-]

Abstract:

Controlling the expansion of capture capacity has been a major challenge for the fisheries management systems around the North Atlantic. Despite focused attempts to reduce this capacity in recent years in different jurisdictions, it has continued to expand. This chapter uses a case study of changes in Norwegian fisheries to help explain why this has happened. The article supports the replacement of the rational actor approach that is currently hegemonic within fisheries management by a relational approach to the analysis of capture capacity expansion. A relational approach offers new insights into the ways political, economic, and technological forces continue to fuel capacity expansion within fishing. By use of this approach the article describes how the harvest machinery comes into existence. Keywords: Fishery policy; Capture capacity expansion; Management models; Cod fisheries; Harvest machinery

The value chain of white leg shrimp exported to the U.S market in Khanh Hoa province, Vietnam

Bui Nguyen Phuc, Thien Chuong (Master thesis; Mastergradsoppgave, Jun-2011)

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.

The role of perceived risk, knowledge, price and cost in explaining dry fish consumption in Bangladesh within the Theory of Planned Behaviour (TPB)

Siddique, Mohammad Abdul Momin (Master thesis; Mastergradsoppgave, 01-Jun-2011)

[+]

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.
