The purpose of this paper is to examine the effects of different label-message formats (positively vs negatively framed messages) on consumers’ purchase intentions in an organic seafood shopping setting, along with the moderating effects of two individual characteristics (purchase-decision involvement and perceived consumer effectiveness (PCE)) on the message-framing performance.

Data were gathered from 1,698 consumers of a supermarket chain in the northeast region of the USA using a web-based experiment.

Results of this study support the superiority of a positively framed message over a negatively framed message in persuading consumers to buy organic food. In addition, this effect of framing on persuasion is contingent upon different levels of consumer purchase-decision involvement as well as PCE concerning organic products.

This study offers managerial implications for marketers and retailers, messages appealing the environmental and health benefits of organic seafood consumption (positively framed arguments) would be more persuasive to increase consumer purchase intention than negatively framed ones. In addition, individual characteristics of their target market should be taken into account in communication design and implementation.

This survey research offers insights into the organic food consumption literature by validating the applicability of message framing in the organic seafood labelling setting and identifying consumers’ individual characteristics (purchase-decision involvement regarding organic seafood and PCE) moderating the message framing effectiveness.

Development of thin film sensors with pH function for noninvasive real-time monitoring of spoilage of packed seafood such as fish, crab and shrimp are described in this study. It is also the purpose of this study to enhance the leaching resistance of the sensors by using a suitable strategy and to quantitatively correlate the sensor’s halochromism with the total volatile amine.

To prepare halochromic sensors with better leaching resistance, biocompatible materials such as starch, agar, polyvinyl alcohol and cellulose acetate along with a halochromic dye were used to prepare the thin film sensors. These thin films were evaluated for monitoring the spoilage of packed seafood at room temperature, 4°C and −2°C up to 30 days. The halochromic sensors were characterized using UV-visible and FT-IR spectroscopy.

CIELab analyses of the halochromism of the thin film sensors revealed that the color changes exhibited by the sensors in response to the spoilage of seafood are visually distinguishable. Further, the halochromic response of the thin films was directly proportional to the amount of total volatile base nitrogen that evolved from the packed seafood. Excellent leaching resistance was observed for the developed thin film sensors. The halochromic property of the sensors is reversible and thus the sensors are recyclable. Besides, the thin film sensors exhibited significant biodegradability.

This study provides insights for use of different biocompatible polymers for obtaining enhanced leaching resistance in halochromic sensors. Further, the color changes exhibited by the sensors are in line with the total volatile amines evolved from the packed seafood. These results highlight the importance of the developed halochromic thin film sensors for real-time monitoring of the spoilage of packed seafood.

The purpose of this study was to investigate the role of consumer altruism and other socio-cultural factors in predicting how much attention consumers pay to seafood eco-labels.

The empirical investigation was carried out by administering an online questionnaire to a sample of Italian and Spanish people from December 2019 to April 2020. After carrying out the principal component analysis procedure, the work made use of an ordinal logistic regression.

Both Italian and Spanish consumers with an altruistic attitude, who feel that food produced in a sustainable way can protect the environment and workers, appear more likely to take an eco-label into account. In addition, in both countries, consumers with a higher level of education and in the older age range are more likely to read eco-labels before buying fish products.

The first limitation is mainly related to the sampling procedure, which is not probabilistic and does not allow for generalisation of the results. Furthermore, some indicators related to COVID-19 were not included as the planning stage of the research methodology occurred before the pandemic.

A better understanding of the main determinants predicting consumers' attention to seafood eco-labels could be crucial to promote effective marketing strategies aimed at increasing consumer interest and awareness in sustainable seafood and eco-labels.

Exploring the role of consumers' altruism in how much attention is paid to seafood eco-labels appears to be a new approach that emphasises the role of altruism as a variable capable of bridging the “value-action gap”.

The purpose of this paper is to gain an understanding of the primary barriers to the implementation of environmental responsibility in organizations.

The paper employs semi‐structured interviews with key informants and site observations. Key informants include top and senior managers of three frozen seafood processing companies in Thailand.

The paper identifies three primary barriers: the lack of a system perspective on seafood sustainability, absence of top management commitment and cultural diversity.

As an exploratory case study, findings cannot necessarily be extrapolated to broader populations. To improve generalization of the findings, future research should broaden the sample. It would also be beneficial to pursue comparative research between industries, countries and regions.

Implementing corporate environmental responsibility requires raising “green culture” ideology throughout an organization. A system perspective on seafood sustainability, top management commitment and proper management of cultural diversity plays a significant role in affecting organizational change towards sustainability.

This paper contributes to a greater understanding of the role of humans and culture in greening the seafood supply chain.

The key findings on implementing ISO 9000 standard in the seafood industry, which is recognized as the leading export industry in Thailand, have been presented. The purpose of this study was to describe the current situation in ISO 9000 implementation, the characteristics, the strengths, the weaknesses, and problems of implementing a quality standard. Reports the finding of a mail questionnaire survey conducted on 178 selected seafood companies. The analysis of the survey data suggested that about 94 percent of companies obtained at least one quality standard. With further analysis, we also found that there are some different characteristics in terms of product type, production process, and purchasing policies among these selected companies. Results indicated that Thai seafood companies still lack enthusiasm regarding ISO 9000, compared with other countries in Asia. Finally, we found major problems in implementing ISO 9000 such as lack of understanding this quality standard and lack of support from the staff and management.

The study aims to provide important insights into environmental attributes that are relevant to consumer's choices in purchasing canned tuna fish, and how much these attributes and socio-demographic individual characteristics relate to the frequency of consumption.

An online survey of 251 Italians was carried out. Socio-demographic variables and environmental attributes of the product that consumers pay attention to were considered in a two-step analysis: a cluster analysis used to create a segmentation of people's profiles that are further characterised; a binary logistic regression to assess the significance of attributes in relation to the frequency of canned tuna consumption.

Among attributes that respondents pay attention to when purchasing canned tuna, the country of origin is the aspect most considered, while other characteristics with a higher content of environmental sustainability received minimal attention. Three clusters emerged: the smallest one, insensitive to sustainability issues; an intermediate group which is mindful of sustainability attributes; and the biggest cluster which is “sustainability inconsistent.” Moreover, respondents who reported concerns about the environmental impacts of tuna production are less likely to consume the product than other consumers; attention paid to the method of farming, the presence of children and a young age show willingness to consume tuna.

This study contributes to the literature on canned tuna consumption by focusing on the attention that consumers pay to environmental product attributes in their purchasing choices. The relevance of this topic might be envisaged in relation to several environmental issues associated with tuna production and consumption, and to the economics and strategies of the tuna industry, being canned tuna among the most internationally traded seafood products.

This study explores the influence of quality attributes and socio-demographics on Chinese consumers' general and online consumption of three origin-specific lobsters: Canadian, United States and Australian.

A web-based survey was administrated to 981 consumers from two cities in China: Shanghai and Qingdao. Descriptive analysis and binary logistic regression were used in the data analysis.

Chinese consumers were more willing to pay for the lobster quality attributes vitality, meat content, texture, size and safety. Their general and online consumption of three origin-specific lobsters is significantly linked to the following quality attributes and socio-demographics: meat content, size, shell hardness, texture, safety, nutrition, age, income, education, occupation, residential place and marital status.

This is the first study to explore the influence of quality attributes and socio-demographics on consumers' online consumption of luxury seafood.

The purpose of the paper was to know and evaluate consumption, preferences and the knowledge of labelling legislation about wild and farmed seafood products.

A sample survey on Sicilian families was conducted through a direct interviews between October 2015 and October 2016 to study the attitudes of Sicilian consumers towards wild and farmed fish and seafood products. A stratified two-stage sampling design was chosen with variable probability of inclusion of the units of first stage and 1,700 subjects were interviewed.

The results obtained showed that the 69.4% of respondent ate fresh fish at least once a week and the 86% of respondents consumed aquaculture products at least once a month. Also, the 77.3% of respondents did not know the current legislation on the labelling. Multiple correspondence analysis allowed to identified three profiles of Sicilian families and binary logit model was used to examine the factors that influenced different frequency of fresh fish consumption in general and farmed seafood products in particular.

Extending the research throughout the Italian territory would have allowed further comparisons at the national level.

The research provides useful information on Sicilian consumers that could be used by policymakers and by marketing communications company.

This research, on a restricted group of European consumers (Sicilian), characterised by living in an island, reinforce the knowledge regarding seafood consumers.

This study used a probabilistic sampling design and a face-to-face questionnaire which produce results more robust in compare to surveys used more frequently such as non-probabilistic sampling design.

In 2020, mechanisms to limit the chain of transmission of coronavirus disease 2019 (COVID-19) in Australia led to widespread restrictions on population mobility and business operations. Such conditions provide a natural experiment that may help to provide insights into consumer behaviour and future trends in food consumption. The overall objective of this study is to explore the possible impacts of COVID-19 on meat consumption patterns in Australia, both in the short and medium term, and to explore whether there have been impacts on the underlying drivers for consumption.

The research reported in this paper analyses the impacts of COVID-19 on meat and seafood consumption in Australia, drawing on a national random survey of 1,200 participants in June 2020. Survey data on past and current consumption rates are compared to respondent estimates of their future consumption behaviour, and ordered probit models are used to identify whether consumption changes can be explained by socio-demographic, attitudinal or economic factors.

Two potential scenarios were evaluated to explore future consumption trends. The first “acceleration” scenario is that the restrictions would encourage people to speed up existing declines in meat consumption, perhaps taking more account of credence factors such as health, animal welfare and environmental issues. The second “transformation” scenario is that people will change consumption patterns, perhaps moving more towards home-cooked meals and increased consumption. Slightly stronger support was found for the transformation scenario, indicating that consumption rates for most meats and seafood will be stable or increase over the next five years.

This study capitalises on changed social and economic settings generated by COVID-19 to test the effects on consumption of meat (chicken, beef, pork, lamb) and seafood at a national level. Ordered probit models are applied to evaluate participant data on their future intentions for meat consumption to test two scenarios, finding stronger support for the “transformative” scenario than the “accelerate” scenario.

This study establishes a set of seafood processing circular supply chain capabilities (CSCCs) in Vietnam using qualitative data analytics. This study specifies the interrelationships and hierarchical structure comprising six aspects and 24 criteria for the seafood processing circular supply chain in Vietnam.

Fuzzy Delphi method is used to confirm the validity. Fuzzy set theory is used to deal with the complexity and uncertainties from the qualitative information. The decision-making trial and evaluation laboratory method is used to examine the interrelationships among attributes. The analytical network process segregates (or displays) the capabilities in a hierarchical structure.

The results show that management control and technological capability dominate in circular design, circular sourcing, circular production and resource recovery. In practices, the strategic planning, action planning, information technology and technological facilities are important to seafood processing industry.

The CSCCs are pivotal in establishing a concrete foundation for the execution of circular supply chain management, with the aim of optimizing resource utilization and eliminating waste; however, prior studies have lacked a focus on the capability associated interrelationships and hierarchical structure in qualitative data analytics.
