The gray wolf (Canis lupus) is a source of concern and a cause of damage to people's livelihoods. In Finland, as in most countries, actual damages are compensated according to the real lost value. However, often, the suffered damages are larger than what is compensated, and worries and fears are not accounted for at all. The purpose of our transdisciplinary action research is to contribute to the process of modifying the scientific, administrative, and everyday habits of mind in order to meet the practical prerequisites of living with the wolf. In 2014, we planned and participated in a process designed to update Finland's wolf population management plan. During our study, we applied e-deliberation, conducted a national wolf survey, and organized solution-oriented workshops in wolf territory areas around Finland. By applying abductive reasoning, we illustrate the basic features of an economic scheme that would help finance and coordinate practical modifications to the ecological, economic, and institutional circumstances and settings in wolf territory areas. The potential economic instrument is based on payments for improved ecostructures. In our paper, we describe the organization, functioning, and financing of this instrument in detail.

Trap fisheries can provide catches of high quality, and unwanted bycatch can be released with high survival. Light attraction could be an effective way of increasing trap catches, but research results are largely lacking. Experiments to test the effect of LED lights in trap‐net fishing were conducted in two Finnish lakes where fishing targeted Eurasian perch Perca fluviatilis L. and roach Rutilus rutilus (L.). LED lights (white, green, red, blue and combinations) were attached inside the traps. The use of LED lights did not increase fish CPUE. Contrary to expectation, Eurasian perch catches were higher in traps without LED lights. Significant variation in CPUEs was observed, but without interaction with light treatments. The LED lights tested in this study do not increase the effectiveness of trap fishery targeting Eurasian perch and roach in Finnish lakes in the ice‐free season.
