Freshwater · A short, tightly regulated winter season on licensed waters
Huchen
Hucho hucho
⚠ HIGHEST-CAUTION STATUS: The huchen is listed as Endangered by the IUCN (2024 re-assessment) and in Habitats Directive Annex II + V. Real licensed fisheries survive only on some Danube tributaries in Germany, Austria, Slovenia and Croatia: a very short season, a high minimum size (commonly 70 cm+), single-fish quotas and club permits — among Europe's most expensive freshwater licences. It is fully protected in other countries (e.g. Romania). Always check the specific water's rules; catch and release is the norm. Also called Danube salmon, it is a close relative of the Siberian taimen.

Identifying features
- Long, torpedo-shaped salmonid body, larger and heavier than any trout
- Small dark spots scattered over a silvery-olive to coppery body, fading with age
- Very large mouth reaching well past the eye, with strong teeth
- Large forked tail and a big adipose fin
- In spawning season males develop a hooked jaw and brighter copper-red flanks
Habits
- An apex river predator eating fish, including grayling and its own young
- Most active in low light and in the cold months when licensed seasons run
- Holds tight to deep cover by day and hunts at dawn, dusk and at night
- Grows very slowly — a metre fish may be decades old
- Territorial and solitary; a known pool may hold a single big fish for years
Distribution
Where to find them

How to catch them
Streamer fly-fishing at dusk on permit beats River

Key tip: Fish first and last light at deep pools and obey every permit rule — one fish per season may be the quota.
Lure spinning with big baits at deep pools River
Rig: Powerful spinning setup with a large wobbler or soft plastic presented slowly along undercut banks and bridge pools where spinning is permitted
Bait/lure: Large wobblers and soft plastics where rules allow
Key tip: Fish slowly and deep, work the famous lies methodically, and keep every fish in the water for a quick, gentle release.
