Abstract

This study reports on awareness-raising initiatives along the River Tagus (Portugal) targeting the spread of the invasive European catfish (Silurus glanis). Activities included public awareness on alien and native species, angler surveys, and culinary demonstrations with sensory evaluations, mobilising anglers and citizens for conservation. Results showed strong support for harvesting this non-native species and high acceptance of European catfish-based dishes. These findings underscore the role of environmental education in managing invasive species in Portugal’s freshwater ecosystems.
