The average of the increment in the mass per day at Day 1 was statistically compared with that at Day 2-10, by paired t-test. No stimulus, the specimens without the mechanical stimuli; Day 1, Day 2-10, the divisions of the period when the specimen put into the artificial seawater at 5˚C; Mechanical stimuli, the specimens with the mechanical stimuli; Pre, before giving the mechanical stimuli to the specimen (corresponding to Day 1); MS, at giving the mechanical stimuli; Post, after giving the mechanical stimuli (corresponding to Day 2-10).
