Outline of Final Research Achievements

Survey experiments were conducted in the sea near the city and small techniques “KOWAZA” were developed to motivate the creation of the SATO UMI and conservation efforts.
As a result, they found a way to improve the canal's environment, which is becoming anaerobic from the bottom to near the surface. Furthermore, we were able to find a technique to create a variety of environments in artificial tidal flats. It was found that placing a structure with voids on the surface could conserve Tridentiger obscurus. In addition, the characteristics of environmental learning programs that lead to a sense of accomplishment, self-affirmation, and conservation activities were clarified. For example, it was found that it was important for learning programs to be content to understand and apply knowledge.
