Aquarium species recorded as invasive
Species a named source calls invasive somewhere. There is exactly one, out of 2,168 distribution statements, and that number is the point rather than an omission.
What this page does not say
Invasive is a claim about harm and it is much stronger than introduced. AquariumHQ reproduces the claim where a source makes it and never promotes an introduction into one — which is why a genuinely notorious species can appear on the introduced page and not on this one.
5 species
Countries are as the source coded them. A species appears once, with every country any held checklist assigned to it under this status.
| Species | Countries | Recorded in |
|---|---|---|
| Asian clam | 1 | SE |
| Chinese pond mussel | 1 | SE |
| Slough crayfish | 1 | SE |
| Spiny-cheek crayfish | 1 | SE |
| Weather loach | 1 | SE |
Where these statements come from
Every row above is a statement made by one of these checklists, retrieved through GBIF with the establishment means reproduced exactly as the source coded it.
- Invasive Alien Species in Sweden (Regulation (EU) 1143/2014)
- Risk assessment of alien taxa in Sweden 2018
Where a checklist recorded presence without coding how the species got there, the record is held as unstated and does not appear on any of these pages. Filling that in would be the single most damaging thing AquariumHQ could do to this dataset.
