Outline of Final Research Achievements

The purpose of this study is to investigate how low frequency underwater noise from offshore wind farm on fish, which is essential knowledge for environmental assesment of offshore wind farm. The results of this study showed that at the onset of exposure to 100 Hz pure tone at a 140 dB re 1μPa/√Hz cause temporal changes in swimming and feeding behavior, however no significant effect on the feeding rhythm, feeding rate and growth of Pagrus major, and sexual maturity, spawning, egg development of Sillago japonica. However, hearing sensitivity and reaction will differ depending on the species, further studies are needed for understanding the effect of underwater noise from offshore wind farm on fish.
