  The paper presents the results of a study of the impact of acoustic and
vibration signals on Black Sea mussels, and determines the necessary technical
characteristics of vibration sensors. A method has been developed based on the
analysis of the time interval recorded by a valve motion sensor in the form of
a monotonically decreasing function after the response of a mussel colony to
the influence of a vibroacoustic signal. The method makes it possible to
eliminate the calibration of the opening value of the mussel valves at the
stage of manufacturing and setting up the biosensor system, as well as to
control and determine false positives or incomplete opening of the valves of
individual mussels when exposed to point stimuli. A structural and functional
diagram of the developed experimental setup is presented
