[The background locomotor activity of the crayfish Procambarus cubensis as an index of the animal's functional status].
Locomotor activity of the American crayfish Procambarus cubensis living for many generations in aquaria was recorded by means of two supplementary non-invasive techniques under the conditions close to its habitat. The single "spontaneous" locomotor act was performed slowly and consisted of several brief "pushes" and long-lasting pauses. Placing the animal into the experimental tank of a simple form caused its investigatory behaviour during 10-15 min, when it demonstrated the maximal speed of walking. "Spontaneous" (background) locomotor activity persisted for more than 10 hours; its average maximum was at night and minimum was in the morning. The background locomotor activity seems to indicate the animal's functional state; it allows to distinguish between quiet wakefulness, alertness or sleep-like state of the crayfish.
