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.","sampling":"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).","qualityControl":"Quality control for geographic data: Reliability of coordinates was checked in Google maps.\nQuality 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).","methodSteps":["The analyses of 99 occurrence record data (CPUE, morphological traits, sex ratio) are discussed in details in Boggero et al.
