Spatial dynamics of the noble crayfish (Astacus astacus, L.) in the Paklenica National Park
Aim of this work was to analyse the spatial dynamics of a noble crayfish population inhabiting the Velika Paklenica Stream (Paklenica National Park, Croatia). The study was conducted in July 2000, and between March and September 2002. Crayfish were trapped by baited LiNi traps and hand-made traps at two localities over 25 nights. We recorded the precise position of the captured crayfish, their sex, and total length. Crayfish were individually marked and then released back into the stream at the same spot where they were caught. Spatial analyses included determination of movement direction, distribution type, home range, total travelled distance, and mean daily movement. The mean home range of approximately 19 m was calculated. No difference in home range between sexes was found. There was a large individual variation in the extent of movement without any effect by sex and size.
