The European bullhead (Cottus gobio) is widely distributed across Europe and within the UK is native to England and Wales, where it is protected under the Habitats Directive. In Scotland, however, the species is considered invasive and thriving popul...

At what spatial scale should risk screenings of translocated freshwater fishes be undertaken – river basin district or climo-geographic designation? (2018)
Journal Article
Dodd, J., Vilizzi, L., Bean, C., Davison, P. I., & Copp, G. H. (2019). At what spatial scale should risk screenings of translocated freshwater fishes be undertaken – river basin district or climo-geographic designation?. Biological Conservation, 230, 122-130

To inform aquatic conservation policy and management decisions, translocated freshwater fish species, i.e. those native to part but not all of Great Britain (GB), were assessed with the Aquatic Species Invasiveness Screening Kit (AS-ISK) at two spa...
