   The process of improving automated systems of biomonitoring of aquatic bodies, using bivalve mollusks as biosensors, is accompanied by the study and analysis of the responses of these living organisms to various possible natural physicochemical and “test” effects. The results of these laboratory and field experiments are used in the creation and modernization of autonomous software algorithms for the operational analysis of valve activity, and using its statistical indicators of automatic decision-making for environmental systems for monitoring and detection of toxic contaminants.

   Experiments were carried out, which were a continuation of laboratory studies of the behavioral responses of these mollusks to physical, chemical and biological effects.

   The results of laboratory and field experiments show that sea  mussels, unlike freshwater mussels, clearly respond to light and sound short-term changes in the environment, which is obviously a consequence of a reflex protective response against a threat (predator).

   The reaction, expressed in terms of the change in the valve activity of the sea mussels, to the shadowing of the light flux is an order of magnitude higher than their reaction to sound effects. In addition, the sea mussels, having a more advanced sensory system, adapt quite quickly to the natural background fluctuations of both external illumination and sound waves, which apparently indicates their higher biological organization compared to the freshwater pearls.

   These findings also show both the advantages and disadvantages of using one and the other mollusk in biosensor technologies and the need to take them into account in the algorithmic and software analysis of automated control systems.

Keywords: bioelectronic control, bivalve mollusk, biosensor, bioindicator, bio-sensor, perl, mussel.
