Fishing Trehörn
perch, pike and zander sit at the top of the food chain in Trehörn, carried by roach and bream. The nutrient-rich water means plenty of baitfish — and predators that grow fat on them.
Whoever fishes Trehörn regularly builds something of their own: a log of what took, where and when. That's how the water gives up its patterns — cast by cast, never all at once.
General rules of thumb for this kind of water
