From: Characterization of the daily and circadian valve behavior of the European flat oyster Ostrea edulis
Experimental setup and protocol. (A) Experimental setup to investigate the circadian rhythm of O. edulis. (B) Experimental protocol. Timeline of the 11 series to which the oysters of both EUs are exposed successively. (C) Zoom of O. edulis equipped with HFNI valvometry electrodes for valve behavior recording. (D) Example of a daily individual valve activity showing the two behavioral parameters chosen in this experiment, i.e. the valve opening amplitude (VOA) and the valve opening duration (VOD). EU: experimental unit. HFNI: high frequency non-invasive.
