Abstract

This study examined the effects of an acoustic stimulus on the haemolymph and agonistic behaviour of the red swamp crayfish, Procambarus clarkii. The experiment was conducted in a tank equipped with a video recording system using six groups (three control and three test groups) of five adult crayfish (30 specimens in total). After 1h of habituation, the behaviour of the crayfish was monitored for 2h. During the second hour, the animals in the test groups were exposed to a linear sweep (frequency range 0.1–25kHz; peak amplitude 148dBrmsre.1μPa at 12kHz) acoustic stimulus for 30min. Exposure to the noise produced significant variations in haemato-immunological parameters as well as a reduction in agonistic behaviour.
