Checklist of non-native freshwater fauna in Portugal

It contains information about non-native freshwater species established in Portugal, including the Azores and Madeira archipelagos between 1800 and 2019. This species checklist was first assembled in 2019 (Anastácio et al 2019) and was enriched with more taxa and information in 2025.

Here it is published as a standardized Darwin Core Archive and includes for each species: the location (mainland, Azores or Madeira), year of first observation, introduction pathway. Issues with the dataset can be reported at github.com/onestop-project/alien-freshwater-fauna-portugal/issues. The publication of this dataset was supported by the OneSTOP project (OneBiosecurity Systems and Technology for People, Places and Pathways, onestop-project.be) funded by Horizon Europe (ID No 101180559), with technical support provided by the Research Institute for Nature and Forest (INBO).
