Project Data
In Piedmont, very few information is available on the distribution of F. limosus while Procambarus clarkii was deeply studied (Piscia et al. 2010; Boggero et al. 2023). The project aims at providing a first picture on the expansion of F. limosus in the Italian North-western lakes including Lake Orta by providing up-to date and georeferenced information.

| Study Area Description | The lake has a fluvio-glacial origin. Its coasts are characterised by steep slopes and by gentler areas where tourism and recreational activities have flourished. Fifteen survey sites were surveyed for environmental characteristics, but only 6 of them were selected for monitoring invasive crayfish. |
| Design Description | An extensive monthly survey on lake Orta shores (2021–2022) to monitor the occurrence and population distribution of non-native crayfish was carried out. From a total of 15 sites characterised for environmental features, 6 were selected for crayfish monthly monitoring. Sampling method: trapping (modified from Garzoli et al. 2020) which involves the use of 13 cylindrical bite traps/site (30 × 60 cm) leaved on site for 12 h (Boggero et al. 2023). |

Sampling Methods
Twenty grams of cat food per trap were used to attract crayfish. The baited traps were placed at each sampling site at night when crayfish are more active, at a distance of about 2–3 m between them and retrieved in the following morning (soak time of approximately 12 h). On retrieval, the number of crayfish caught in each trap was recorded and by-catch of incidental non-target native species released (Boggero et al. 2023).
| Study Extent | Lake Orta is a well-studied example of how a strong water acidification due to copper and ammonium sulphate discharges could collapse a whole biocoenosis in a lake (Bonacina 2001). Following its chemical recovery, accelerated by a liming intervention (Calderoni et al. 1991) carried out by the Italian Institute of Hydrobiology in Pallanza (currently Water Research Institute, CNR-IRSA), the lake has gradually been repopulated, with the reappearance of new species. |

| Quality Control | Quality control for geographic data: Reliability of coordinates was checked in Google maps. Quality control for taxonomic data: Specimens were assigned to taxonomic units according to the available literature and identification keys by the creators of the dataset (taxonomic experts in the field). |
Method step description:
- The analyses of 99 occurrence record data (CPUE, morphological traits, sex ratio) are discussed in details in Boggero et al. (2023).
