Outputs of a periodogram analysis (i.e., the periodicity P in min and the percentage of variance V%, as a measure of the strength of detected rhythms) of the time series of locomotion data for three Nephrops held together in a microcosm tank, obtained using RFID and automated video tracking during two consecutive laboratory experiments.
