Attitude toward and Consumption of Fish in Vietnam

This study uses theory of planned behaviour (TPB) as a conceptual framework to investigate the attitude and intention toward the consumption of fish in a cross-sectional survey of Vietnamese consumers. Structural equation modelling (SEM) is used to test the reliability, validity, and relationships in the proposed model. The results show that the variation in the frequency of fish consumption is significantly explained by intention and perceived behavioural control. Intention to consume fish is significantly determined by subjective norms and attitude toward consuming fish as a meal. Perceived behavioural control is significantly related to fish consumption, but not to the intention to consume fish, indicating that there may be a difference between perceived control and actual control. At the specific-belief level, the study found that negative affect, perceived quality, and price are significant indicators that explain 60% of the variation in attitude. Perceived price, time needed to cook and prepare fish as a meal, and the availability of fresh fish are important factors explaining 63% of the variation of the perceived control over fish consumption. The study also provides some managerial implications and suggestions for the seafood sector to expand the domestic markets and gives recommendations for future research.

稻田低密度生态养鱼及其实现产业化的前景

稻田低密度养鱼是一种新型的、具有较强的自我修复能力的农田生态系统模式,它集农产品消费安全、农民快速增收、稻田地力培肥、农副废弃物资源化于一体,且有三省(省工、省肥、省药)、两低(降低生产成本,降低劳动强度)的特点,体现了我国生态农业的特色和精华,即巧妙借用自然力(如养鱼、养鸭等)以实现轻轻松松地种田,既有助于农业的可持续发展,又促进了农村经济的发展和农村工业化、城镇化进程。     

Fish Consumers: Environmental Attitudes and Purchasing Behavior

The objective of this study was to expand on the limited awareness of the U.S. fish consumer. Measures were tested through a Web-based national survey. The final survey consisted of 40 questions, including environmental awareness, food neophobia, fish consumption, reasons for consuming fish, and demographic variables. Correlations and t tests were used to analyze relationships between eating fish in restaurants and other variables. Hierarchical cluster analysis was used to segment respondents into two groups based on their environmental awareness and neophylic/neophobic attitudes. EcoFish consumers were more likely to be male, eat fish for health and the environment, and eat fish at restaurants significantly more than the Indifferent Fish consumers. Restaurants can use these results to market to eco-friendly, health-conscious fish consumers.
