In this study we have investigated the effectiveness of a one day school-basedintervention with recreational fishing (in Swedish called Klassdraget) in increasingenvironmental awareness, interest in nature and recreational fishing in pupils agedbetween 8 and 12. Our results suggest a weak positive association between exposure tonatural environments in a recreational fishing context and interest in nature andrecreational fishing. We found the intervention to have no effect on the frequency offishing, interest in fishing more, or number of visits in nature during spare time.Knowledge about nature and possibly also environmental awareness are positivelyaffected and these effects can be traced as long as three years after the intervention. Ourfindings also reveal a low correlation between frequency of nature visits and selfreportedinterest in nature. The observed effects of Klassdraget are small but appear tobe larger for girls, who are traditionally less interested in recreational fishing whencompared with boys.
