An important element for the protection of biodiversity is the willingness of the public to support restoration efforts. Using a longitudinal survey design with 1,000 respondents each in France, Germany, Norway and Sweden, scientists led by the Leibniz Institute of Freshwater Ecology and Inland Fisheries (IGB) investigated which values, beliefs and norms promote conservation-oriented behavior toward native fishes in rivers. The study shows: Germans have little connection to fish. Rather, the protection of fish in this country is supported by general pro-ecological values and norms. In France, Sweden and Norway, on the other hand, native fish species have great influence on individual conservation-oriented behavior. The results explain why some countries make higher investments in fish species conservation and why fish-related issues are differently represented in political discourse.


Freshwater ecosystems are home to about one third of all vertebrate species and 43 percent of all fish species worldwide. In Europe, more than 40 percent of native freshwater fish are threatened or already extinct: River regulation, hydropower and damming, pollution, climate change, invasive species and, to some extent, overfishing are the main causes. So it depends on our actions how water bodies and fish species develop. To better protect rivers and fish stocks, citizens have to be convinced. But not every argument works: As this study shows, it is important to consider the cultural context within which the public perceives and reacts to threats to biodiversity.

Researchers from the IGB and the Humboldt Universität zu Berlin, together with international partners, applied the value-belief-norm theory from conservation psychology to investigate what environmentally friendly behavior depends on, using the example of fish species protection. Dr. Carsten Riepe, first author of the publication in the scientific journal Society and Natural Resources, said, “The unique approach of our study is that we did not only look at behavioral intentions, but also surveyed actual behavior in natural settings, for example people’s willingness to make monetary donations that benefit fish species conservation in rivers. This increases the significance of our survey enormously.”

Same basic ecological values, different affinity for fish

Respondents in the four countries showed similar environmental beliefs, attitudes and norms. For example, basic ecological values and the conservation of biodiversity in and around rivers were important to the majority of all respondents. The majority even tended to feel morally obliged to mitigate threats to the decline of fish species diversity in rivers.

However, there were also some relevant differences in the four countries: The survey results from Norway, but also from Sweden and France, indicate a higher attachment to fish and the aquatic environment. In these three countries, the protection of native fish species was a particularly important determinant of conservation-oriented behavior. In Germany, on the other hand, the general ecological context was more crucial. In comparison to the other three countries, Germans showed little connection to fish and the aquatic environment.

Ecological and societal differences between the countries affect social and political perceptions of fishes and rivers

“The four study countries differ in their fish communities and the status of their freshwaters. There are also cultural, recreational and socio-economic differences. These factors influence conservation-oriented thoughts and behaviors in relation to fish species conservation. The results explain why some countries make higher investments in fish conservation, why fish-related issues appear differently in political discourse and why there are differences in the societal importance and perception of fish and fisheries between European countries,” explained project leader Professor Dr. Robert Arlinghaus from IGB.

Important insights for environmental education

From the results, the researchers derived insights for effective environmental education and intervention campaigns. Effective information and education measures—for example initiated by the government or by non-governmental conservation organizations—need an argumentative framework that strikes a chord with the addressees: “One promising way is to embed the core message of an information campaign in a narrative that makes country-specific references to the way the environment is perceived. While topics and facts about wild salmon or brown trout excite people in Norway and Sweden, Germans are more likely to be reached with general topics such as water quality or threats to biodiversity as a whole,” Carsten Riepe says.
