We do, a few rivers on the west coast, and some on the east (baltic salmon counts as the same species).
The far north is getting pretty decent, apparently.
We used to have 228 salmon rivers, but hydroelectric dams, logging routes and pollution has taken it down a few notches, to 30 something.
Pike and perch are everywhere, and they do grow big, especially in the baltic archipelago. Some bloke got an 18,1 kg pike earlier this spring (that's a hair short of 40 lbs). That'd be fun to try some day.
