Investigation of chloramine-T impact on crayfish Astacus leptodactylus (Esch., 1823) cardiac activity

Popis výsledku v původním jazyce

The crayfish play an essential role in the biomonitoring and may reflect ambient water quality through the biochemical, behavioural and physiological reactions. To assess whether narrow-clawed crayfish Astacus leptodactylus can respond by heart rate changes to presence in water of such biocide as chloramine-T, adult males were exposed to its low (2 and 5 mg L-1), moderate (10 mg L-1, commonly used in industry and aquaculture) and exceeded (20 and 50 mg L-1) concentrations. In addition, a physical stresstest evaluated energy expenditure following the chemical trials. Three key reactions (cardiac initial, first-hour and daily prolonged exposure) were discussed with particular focus on crayfish initial reaction as the most meaningful in on-line water quality biomonitoring. After short-term exposure to both chloramine-T concentrations, crayfish were found to respond rapidly, within 2-5 min. According to heart rate changes, the 1-h exposure did not adversely affect crayfish at either conce
