“…This hypothesis is reinforced by previous observations showing that the activation of such networks, more particularly lateral giant neuron networks, is able to directly stimulate 5-HT neurons in lobster abdominal ganglia (Horner et al, 1997). Although an increase in the 5-HT level could be a direct consequence of tail flip network activation, crayfish may also experience many other stressful situations that are not directly related to tail flips (Elwood et al, 2009), and that may also lead to ALB (our unpublished observations). It is thus possible that several other networks involved in the stress response could similarly stimulate an increase in 5-HT and lead to ALB.…”

In the animal kingdom, biogenic amines are widespread modulators of the nervous system that frequently interact to control mood. Our previous investigations in crayfish (Procambarus clarkii) have established that stress induces changes in brain serotonin (5-HT) concentrations that are responsible for the appearance of anxiety-like behavior (ALB). Here, we further analyze the roles of 5-HT and another biogenic amine, dopamine (DA), on the crayfish response to stress. We show that the intensity of crayfish ALB depends on the intensity of stressful stimulation and is associated with increased concentrations of 5-HT in the brain. These 5-HT levels were significantly correlated, before, as well as after stress, with those of DA, which were approximately 3-to 5-times less abundant. However, whereas the degree of ALB was clearly correlated with brain 5-HT concentrations, it was not significantly correlated with DA. Moreover, in contrast to injections of 5-HT, DA injections were not able to elicit a stress response or ALB. In addition, 5-HT and DA levels were not modified by treatment with the anxiolytic chlordiazepoxide, confirming that suppression of ALB by this GABA-A receptor ligand acts downstream and is independent of changes in crayfish bioamine levels. Our study also provides evidence that the anxiogenic effect of 5-HT injections can be prevented by a preliminary injection of 5-HT antagonists. Altogether, our results emphasize that the rises in brain concentrations of 5-HT, but not DA, play a role in controlling the induction and the intensity of crayfish ALB.

“…To return to the class of crustaceans, research found that not only mussels but many other crustaceans release hormones when they are exposed to situations that might be stressful (Elwood et al 2009). Not only have Chasmagnathus crabs been shown to be able to learn to avoid electric shocks (Fernandez-Duque et al 1992), but shore crabs (Carcinus maenas) have also been observed to vary their avoidance behaviour depending on whether several aversive stimuli are present, showing that their avoidance behaviour is not an uncontrollable reflex that might have indicated no more than unconscious nociception (Elwood et al 2009).…”

“…Crustaceans might experience pain and stress in ways that are analogous to the experience in vertebrates (Elwood et al, 2009). Potentially painful stimuli applied to vertebrates typically produce physiological responses (behavioural changes such as an avoidance reaction), and changes in blood flow, respiratory patterns, and biochemical and endocrine processes (Elwood et al, 2009).…”

SUMMARYThis 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dB rms 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.
