Cool, oxygen-rich rivers and lakes, preferring clear streams. In many waters it does not breed naturally and is stocked, for example in trout lakes.
Insects and their larvae, freshwater shrimp, worms and small fish.

Up to around 80 cm and 10 kg; record from a natural water according to Wikipedia around 19.1 kg (Alaska, 1970). Most do not live longer than 7 years, the maximum observed is 11 years (Wikipedia).
Protection and rules
Closed seasons and minimum sizes are set by each German state (and by each country abroad) and can be stricter on individual waters. We are building an overview with sources and check dates. Until then, check the local fishing regulations and the rules of the club or permit for your water.
In the kitchen
Tender, mild flesh, ideal pan-fried, steamed or smoked; cooked whole, the bones come away easily.
