N2 - The changes in heart rate and circadian cardiac rhythm of crayfish Pontastacus leptodactylus Esch. kept in a lightning regime that is close to natural under optimal or low pH values were studied. The heart rate was registered in real time using an original noninvasive fiberoptic method. Upon acidification, disorders in circadian cardiac rhythm and organism reaction (by heart rate) in the suspension test were detected. The characteristics of cardiac activity are considered criteria for estimating the crayfish's functional state at normal and stress conditions caused by the changes in the quality of the environment.
