Telemetry of co-occurring noble crayfish (Astacus astacus) and stone crayfish (Austropotamobius torrentium): diel changes in movement and local activity

Popis výsledku v původním jazyce

Knowledge of movement patterns is essential for the effective conservation of noble crayfish (Astacus astacus) and stone crayfish (Austropotamobius torrentium). Telemetry was used to evaluate diel changes in ranging behaviour and local activity of both species. Both species migrated mostly in the upstream direction. Movement probability differed significantly within both species between phases of the diel cycle. Movement probability within 3-h tracking intervals was highest at dawn (18.18 %) and night (15.32 %) in A. astacus, and at dawn (37.25 %) in A. torrentium. Astacus astacus moved the longest distances during the dawn interval (3.70 m) and the shortest during the day (1.41 m) and night (1.61 m) interval. Local activity was highest at dusk in A. astacus and during dusk and night hours in A. torrentium. Both species exhibited a post-handling fright response, which (e.g. in mark-recapture studies) can lead to the overestimation of movement rates and the extent of natural migrations.
