| Outline of Final Research Achievements |
The research was conducted for the development of the resource survey method of sakura shrimp in Suruga Bay with scientific echosounders. Parameters for theoretical prediction of target strength, which is acoustic scattering strength, of a single sakura shrimp essential for the survey were determined and its acoustic frequency dependence and body length dependence were clarified. Quantitative observation of the sakura shrimp echo by a scientific echosounder was also successfully conducted and its characteristics were clarified.
