In 2017, we carried out preliminary inspections to record the environmental features of the shorelines and to develop a standardized sampling protocol. We set the minimum distance between two different recording stations at 1.5–2 km along the coastline, to cover the entire perimeter of the lake. We assessed the occurrence of alien crayfish by visual encounter surveys in the sites visited for preliminary inspections. We standardize research efforts by setting visual assessment time at 20 min/site. In parallel, local fishermen were interviewed to gain anecdotal data on the distribution of the species (Garzoli et al. 2020).","relatedProjects":[],"abstract":"From April 2017 to July 2018, we inspected seventy-five sites along the coastline to verify crayfish occurrence. We recorded, for the first time, the signal crayfish Pacifastacus leniusculus (Boggero et al. 2018). Additionally, we found few individuals and remains of the red swamp crayfish Procambarus clarkii, and confirmed the presence of a consistent population of the spiny-cheek crayfish Faxonius limosus (Garzoli et al. 2020). Given the high number of F. limosus’ individuals found, it was possible to perform in-depth biometric and ecological analyses for this species only. We observed no significant differences of biometric measures between males and females of F. limosus (Garzoli et al. 2020)."},"samplingDescription":{"studyExtent":"The Invasive Alien Species in Lake Maggiore monitoring project (SPAM) was a pilot study that allowed us to detect the occurrence of three invasive species, and to shed some light on the auto-ecology of the most abundant species, F. limosus. The finding of P. leniusculus in the Swiss part of the lake is worrisome because of the proximity of the Bolle di Magadino Nature Reserve, and of several source population of the native Austropotamobius pallipes in the lake catchment.","sampling":"We set the minimum distance between two different recording stations at 1.5–2 km along the coastline, to cover the entire perimeter of the lake, for a total of 75 sampling stations (Garzoli et al. 2020). In a second step, we selected eight sites on both eastern and western lake sides, to confirm the previous findings and for a deeper investigation through trapping, by drawing an imaginary line of representative sites along the north-south axis of the lake. We carried out sampling procedures tailoring the protocol described in Tricarico et al. (2017) to a deep and large lake, placing 25 wire mesh double entrances cylindrical traps (30 × 60 cm) for each site, at a regular distance of ca. 10 m to one another.
