Sažetak
The signal crayfish, Pacifastacus leniusculus (Dana, 1852), is one of the most widespread invasive crayfish species in Europe. It has recently invaded a karstic river in central Croatia, the Korana River, and is expanding its range at both the upstream and downstream direction. The spring of this river is within Plitvice lakes National Park, which is known for its unique natural and geomorphological phenomena, and which hosts populations of two native and protected crayfish species. The aim of this study was to monitor upstream expansion of the signal crayfish and to test mechanical control strategies at this upstream section. Research was performed in autumn 2016, with 4 day trapping sessions performed for three consecutive months. Within one year, the invasion front has moved upstream and is now localized within 90 km of the upper reach of the Korana River. For control purposes, we identified a signal crayfish population of high-density, which was the closest to the upstream invasion front. Here we report the results of the control campaign performed at two selected sites (upstream invasion front and the closest high-density population), discuss the efficiency and cost-effectiveness of the chosen approach, and thus suggest potential guidelines for activities aimed at conservation of the invaded karstic Korana river and its native crayfish fauna.
