How Did the Czech Fishing Union Convince over 99% of Czech Recreational Anglers to Report Their Harvested Fish and Their Fishing Visits into Their Angling Logbooks?

This study summarizes the recommendations regarding how to set a recreational angling reporting system where over 99% of the anglers report their harvested fish and their fishing visits. We conducted 40 in-depth interviews with anglers and managers of fisheries, where we asked about the reporting of harvested fish and fishing visits and about compliance with reporting and fishing rules. We achieved the high reporting rate by implementing a mandatory reporting system using angling logbooks, where anglers must write down all harvested fish and all fishing visits. The anglers must return the filled in angling logbooks to continue angling legally. The compliance of anglers with the fishing rules is enforced through field inspections by angling guards. The Czech Fishing Union explains the reasoning behind the fishing rules through local angling organisations where the fishery managers know the anglers personally, arguing that if the anglers do not comply with the angling rules, there will be no fish left to catch in the future. Keeping anglers informed regarding any changes to angling rules is critical for maintaining trust. The effective reporting system requires mandatory angling logbooks, but the communication between the Fishing Union and their anglers is essential to ensure that anglers comply with the system.
