The importance of maritime heritage in providing benefits such as a sense of place and identity has been widely discussed. However, there remains a lack of comprehensive quantitative analysis, particularly regarding monetary valuation and its impact on people’s preferences. In this study, I present the results of a choice experiment that assesses the value of the maritime cultural heritage associated with shrimp fishing through seafood consumption preferences in Germany. Additionally, I investigate people’s attitudes toward cultural heritage and examine how these attitudes affect their stated preferences. I find that these attitudes are significantly stronger in towns where local fishermen led a prominent awareness campaign on fishing culture during the study period. Moreover, I observe a positive willingness to pay for a cultural heritage attribute in shrimp dishes, which varies depending on individuals’ attitudes toward cultural heritage.
