Abstract: Fish supply worldwide has increased significantly in recent decades, driven by the growing demand for food in developing economies, especially Asia. Many developed countries, including Japan, have implemented health policies that promote fish consumption. Despite efforts to encourage consumers to purchase fish, Japan has not achieved satisfactory results due to competition from cheap livestock products. The purpose of this study is to understand how consumers compare fish to other protein sources and how different consumer attributes influence the purchase frequency of fish. We used factor analysis to create a perceptual map of consumers' evaluations concerning protein sources, and a Bayesian hierarchical model incorporating individual heterogeneity to model purchase frequency. Our results show that Japanese consumers place great importance on availability when evaluating protein sources, and that fish is considered less available than other livestock products. In addition, Japanese consumers still prefer wild fish to farmed fish in terms of quality. Individual consumer attributes, such as age, household structure, and eating habits, were found to influence the decision to purchase fish. Consumers’ first-hand fish-related experience is found to be an important determinant of fish consumption. However, the effect of their knowledge identified in the conventional model was not detected in the Bayesian model. These results suggest that experiences allowing consumers to feel closer to fish are more effective than exposure to excessive information campaigns. Using lessons from Japan, this research could aid policymakers and suppliers of fish products to fashion appropriate and effective strategies for encouraging greater fish consumption.
