Project Data
We carried out monthly survey on lake Mergozzo (from June 2021 to May 2022) to monitor the occurrence and population distribution of non-native crayfish. In total 54 records of occurrence of F. limosus at 4 sampling sites are included in the dataset.

| Study Area Description | Piedmont region, lake Mergozzo (45°57.33′N; 08°28′E). Lake Mergozzo shows only the municipality of Mergozzo along its coasts, and a special protection area (ZPS) “Lago di Mergozzo and Mont’Orfano” (IT1140013). The lake is oligotrophic because no direct inputs of anthropogenic origin exist along the lake-shores. |
| Design Description | The crayfish were captured by trapping (modified from Garzoli et al. 2020) which involves the use of 13 cylindrical bite traps/site (30 × 60 cm). Twenty grams of cat food per trap were used to attract crayfish (Boggero et al. 2023). |

Sampling Methods
The baited traps were placed at 4 sampling sites at night when crayfish are more active, at a distance of about 2–3 m between them and retrieved in the following morning (posed for approximately 12 h) (Boggero et al. 2023). The sampling was performed monthly form June 2021 to May 2022.
| Study Extent | Monthly sampling by trapping at 4 sites in Lake Mergozzo. |
|---|---|
| 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:
- On retrieval of the traps, the number of crayfish caught in each trap was recorded and by-catch of incidental non-target native species released (Boggero et al. 2023).
