Order testing
The ruffe (Gymnocephalus cernua) is a small, spiny freshwater fish found in lakes, rivers, and canals across the UK. While native to parts of Europe and introduced to the UK, it has become an invasive species in some water bodies, particularly in Scotland, where it has disrupted local ecosystems. Ruffe are opportunistic feeders, preying on invertebrates and fish eggs, which can impact native species, including important populations of whitefish.
March, April, May, June, July, August
Spawns between March and May with peak eDNA detection probability between April and June. Benthic, so sample near substrate in slow/still water. Invasive outside of its native range (Anglian rivers / Scottish lochs)
