Cooperation of recreational anglers is indispensable to prevent ayu cold-water disease, but the present status for their understanding has been insufficiently evaluated. We here report a questionnaire survey on the anglers' awareness in a local ayu-fishing competition of Mie Prefecture. A total of 598 responses from 2015 to 2018 were considered of 393 (65.7%) responses with taking preventative measures and 135 (22.6%) responses taking no measure. Among the 150 repeaters who were able to pursue their answers, 22 persons improved their awareness whereas 20 persons stopped taking measures or provided unclear answers. These suggest an incomplete status still requiring further enlightenment.
