AN EVALUATION METHOD OF EVACUATION SHELTER FUNCTION DURING HIGH WAVES WITH FISH LIVING IN THE COLD REGION FISHING PORT

Abstract

 In this study, in order to propose a method for strengthening protection and nursing function in the cold region fishing port, we examined the effect of wave height on fish behavior and the method of evaluating the evacuation shelter function on fish during high waves in the fishing port. For that purpose, we took interval photographs of fish, observed the physical environment, and analyzed the wave field around the fishing port. As a result of the analysis, the number of individuals and the frequency rate of appearance decreased as the wave height increased, and no fish were observed above a certain wave height. Therefore, it was considered that the high wave height affected the behavior of fish. In addition, it was possible to evaluate the difference in the strength of the function among the division areas, by the proposed method of evaluating the evacuation shelter function of each division area in the fishing port by the wave height threshold. Although detailed examination is required in the future, this evaluation method can quantitatively evaluate the evacuation shelter function, and is considered to be useful information for the functional enhancement.
