Spawning is assumed to occur in response to stormy weather, but this hypothesis remains untested. In the laboratory (August 2014), the behavior of abalone from Iwate Prefecture, northeastern Japan (39°36’N, 142°2’E) was recorded using 3-axis acceleration data loggers. Egg-releasing behavior was characterized using the predominant frequencies and amplitudes of time series acceleration data. Subsequently (October 2015), the putative egg-releasing behavior of abalone in the wild was recorded at the collection site, using the 3-axis acceleration data loggers. Further field observations using this system on H. discus hannai and other abalone species are expected to facilitate identification of the principal factors stimulating abalone spawning.
