Definition

Linguistics
Semantic Notes
In modern English, 'ruffe' is almost exclusively a noun for the fish. Its use is specialist and not found in general vocabulary. It is unrelated to the more common word 'ruff' (a collar or bird's neck feathers).
Dialectal Variation
British vs American Usage
Differences
The fish is native to Eurasia and is a known invasive species in the Great Lakes region of North America. The term is thus used in ecological/biological contexts in both varieties, but is better known to the British public.
Connotations
Ecological concern, especially in US contexts regarding the Great Lakes. Neutral biological term in the UK.
Frequency
Extremely low frequency in both. Slightly higher in UK media due to presence in local waterways; appears in US conservation texts.
