Welcome to the underwater world of Finnish fish at Maretarium!
At the Maretarium you will get to know Finnish aquatic nature. Finland has 187,888 lakes, 25,000 km of rivers and 46,000 km of coastline of the Baltic Sea and its islands. About 60 native and permanent fish species live in Finnish waters. There are dozens of fish species that visit Finland’s sea area occasionally. You probably know perch, eel, pike, flounder and roach. But do you identify a roach from a rudd, a small whitefish from a vendace or a trout from a salmon? Do you know what kind of fish are gudgeon, chub, minnow or tench?
