Forecasting market demand - Greater amberjack - Internationalization strategy

For farmers of new fish species, market adoption is needed in order to grow a viable business. Farmers may try to sell the new species in their firms’ domestic markets, but they might also look at other markets. However, as markets are becoming more global and competitors more international, considering internationalization may be a necessity rather than a choice. Using diffusion modelling, and based on results of an online supermarket experiment, the innovation and imitation parameters are estimated and diffusion curves for five countries predicted in an attempt to determine the best lead market for introducing fillets of farmed greater amberjack (Seriola dumerili). The production capacity consequences of implementing different internationalization strategies (i.e. “sprinkler” and “waterfall”) were also explored. A waterfall strategy refers to the sequential introduction of a product in different markets, whereas the sprinkler strategy concerns the simultaneous introduction of a product in multiple international markets. Since a sprinkler approach requires many resources and the ability to quickly ramp up production capacity, a waterfall approach appears more suitable for farmers of greater amberjack. Italy and Spain appear to be the best lead markets for greater amberjack farmers to enter first.

“One Fish, Two Fish, Red Fish, Blue Fish” : How ethical beliefs influence consumer perceptions of “blue” aquaculture products?

Aquaculture products - Consumer perceptions - Ethical beliefs

Respecting ethical beliefs of consumers is an important precondition for food manufacturers in their attempt to improve their positioning in the European food market. Based on a cross-cultural survey of 2511 European participants, this research demonstrates how ethical beliefs affect consumer perceptions of “blue” (i.e. environmentally friendly) aquaculture products. The study further emphasises that the positive effect of ethical beliefs on purchase intention operates via an indirect route mediated by consumers’ trust in a product category. Consumer involvement has limited moderation effect on the above relationships. To expand its “blue” business, a key policy recommendation to aquaculture product manufacturers and policy makers is to urge stable and reliable standards of control in environmentally responsible aquaculture production so that consumers can rely on the information source and increase their trust in aquaculture products.

A cross-cultural perspective on impact of health and nutrition claims, country-of-origin and eco-label on consumer choice of new aquaculture products

Aquaculture products - Choice experiments - Country-of-origin - Eco-label - Health claims - Nutrition claims

Over the last decade, an increasing number of new value-added aquaculture products made their way onto the European market, as a response to growing demand for healthier diet, and more sustainable and locally produced protein sources. The importance of these drivers of consumer choice for aquaculture products' acceptance paves the way for a relevant reorientation of the European aquaculture industry towards a more consumer-centred approach. This research uses discrete choice experiments to examine the effect of health and nutrition claims, country-of-origin (COO), and eco-labels on consumer choice of new aquaculture products in a cross-cultural context. Three products with different preserving methods have been chosen for the study: fresh (chilled), canned, and smoked product. Results indicate that COO label “produced in own country” together with ASC eco-label function better than the health and nutrition claims as driver of choice. Results further point to the existence of different segments of “nutrition conscious”, “ethnocentric”, “price conscious”, and “eco-conscious” consumers.

Consumer perception - New aquaculture product ideas - Projective and creative techniques

Involving consumers in the process of modification and creation of new food products has been recently identified as a vital factor for new product development. However, little attention has been devoted to consumer-generated product solutions, and instead, researchers continue to view new product development process as a firm-centred activity. This study uses projective and creative research techniques to involve consumers in the process of modification and creation of new aquaculture product ideas. We provide guidelines for the use of these techniques in the new product development process, as well as managerial and practical implications for the future development of new aquaculture products.

Consumer perceptions - Fish (food) - Involvement - Segmentation

Purpose: The purpose of this paper is to investigate possible cross-cultural consumer segments in the EU aquaculture market and provide direction and focus for marketing strategies for farmed fish products. Design/methodology/approach: Selected psychographic constructs (i.e. category involvement, domain-specific innovativeness, subjective knowledge, suspicion of novelties and optimistic bias) are tested as segmentation basis with the objective of defining a number of cross-border consumer segments with distinctive and clear-cut profiles in terms of consumer perceptions towards farmed fish. Findings: Based on the consumer psychographic profiles, three distinct segments are found: involved traditional, involved innovators and ambiguous indifferent, of which the first two constitute especially interesting targets for market positioning strategies for aquaculture products. Practical implications: The results of the segmentation analysis opens new horizons in terms of positioning and differentiation of fish products from the aquaculture industry according to the most important potential market segments. Originality/value: The current research brings insights into different pan-European consumer segments and their characteristics that allow for a corresponding differentiation strategy within the aquaculture industry. The fact that the segments tend to be uniform across all countries suggests a relatively homogeneous or converging European fish-related culture.

Crises in food risk management have often been attributed to disconnection between the stakeholders involved, as when consumers do not believe risk communications or dispute risk managers' priorities. Before this problem of disconnection can be resolved, however, there is a need to clarify the nature and extent of perceptual discrepancies between stakeholders and to establish whether mutual understanding is attainable. Our recent research has identified that food risk experts and consumers do have different interpretations of what it means for risk management to be effective. Here we describe a study that used telephone interviews to present food risk experts and consumers in four different European countries with statements (derived from our previous work) indicating the different expert and consumer perspectives on food risk management, in order to assess the participants' reactions to these. We found that, though there were areas of agreement between the experts and consumers (for example, they agreed that consumers lack relevant knowledge, that food safety is a shared responsibility and that scientific uncertainty cannot be completely avoided), there were other areas where disagreement remained (for example, on the acceptability of economic interests in food risk management and the role and quality of media reporting). These results indicate the key areas where mutual understanding and appreciation are lacking between significant stakeholders, and hence the areas that should form the target for the activities of organizations like the European Food Safety Authority in order to improve the effective implementation of food risk management practices.

In developing and implementing appropriate food risk management strategies, it is important to understand how consumers evaluate the quality of food risk management practices. The aim of this study is to model the underlying psychological factors influencing consumer evaluations of food risk management quality using structural equation modeling techniques (SEM), and to examine the extent to which the influence of these factors is country-specific (comparing respondents from Denmark, Germany, Greece, Slovenia, and the United Kingdom). A survey was developed to model the factors that drive consumer evaluations of food risk management practices and their relative importance (n = 2,533 total respondents). The measurement scales included in the structural model were configurally and metrically invariant across countries. Results show that some factors appear to drive perceptions of effective food risk management in all the countries studied, such as proactive consumer protection, which was positively related to consumers' evaluation of food risk management quality, while opaque and reactive risk management was negatively related to perceived food risk management quality. Other factors appeared to apply only in certain countries. For example, skepticism in risk assessment and communication practices was negatively related to food risk management quality, particularly so in the UK. Expertise of food risk managers appeared to be a key factor in consumers' evaluation of food risk management quality in some countries. However, trust in the honesty of food risk managers did not have a significant effect on food risk management quality. From the results, policy implications for food risk management are discussed and important directions for future research are identified.

In designing and implementing appropriate food risk management strategies, it is important to examine how key stakeholders perceive both the practice and effectiveness of food risk management. The objective of this study is to identify similarities and differences in perceptions of, and attitudes to, food risk management practices held by consumers and experts with an interest in food safety. Focus groups were conducted in five European countries chosen for their (hypothesised) cultural differences in attitudes towards risk: Denmark, Germany, Greece, Slovenia and the UK. Content analysis was carried out on the resulting texts and (sub) categories were identified within the analysis framework to facilitate the capture of emerging themes. Five key themes were identified as common to the perceptions of both consumers and experts, although these are not represented in the same way by both groups. These key themes are: (1) efforts made by the responsible authorities to manage food risks; (2) responsibility for prevention and management of food risks; (3) how priorities are established within regulatory systems; (4) scientific progress and its implications for food risk management; and (5) media attention and food safety incidents. Although some similarities emerged between the groups, differences were also identified. For example, experts appeared to be highly negative about media influences, whereas consumers appeared more indifferent about media influences and motives. These different perspectives need to be addressed in order to reduce the perceptual distance between key stakeholders, and in particular, to enhance consumer confidence in the food risk management system. Based on the study findings, recommendations for food risk management policies are outlined.
