Cover Story: Valvometry (registration of gaping activity in bivalve mollusks) and photoplethysmography (registration of cardiac activity in mollusks and crustaceans) are currently used to study the physiological status of shellfish species and monitor aquatic systems. Our paper summarizes Russian experience in this field. Valve movement responses to stressors include the complete closure of shell valves, decrease in the distance between valves, rapid shell opening, and higher closing frequency. Cardiac activity reactions of shellfish to stress factors include rapid increases in heart rate and stress index, higher variability in heart rate, and longer periods required for heart rate recovery after stress. The most common bioindicators are mussels, scallops, crayfish, and red king crabs. View this paper
