Effect of chloride content in water on heart rate in narrow-clawed crayfish (Astacus leptodactylus)
Original language description
A non-invasive method of recording cardiac activity was used to examine the impact of chloride level in water on narrow-clawed crayfish. This method permits to record heart rate without any harm to the animal, and also locates changes of the shape and amplitude parameters of the response, which characterized the crayfish functional state. Altogether, 8 levels of chloride (100, 400, 800, 1600, 3200, 6400, 12800 and 25600 mg.l-1 NaCl) were evaluated. Already at low levels some crayfish were influenced. Aclear reaction was evident starting from 3200 mg/l NaCl. On the contrary, crayfish showed a high tolerance to high chloride levels, and heart rate and stress index returned to normal within a few minutes or hours after NaCl addition.
