Welcome to the underwater world of Finnish fish at Maretarium!

In Maretarium you will meet the most of the Finnish fish species. Some species you may see both as small juveniles as old adults. Fish in Maretarium live according to the Finnish four seasons. If you are lucky enough, you may see spawnings. February is a spawning time for burbot and four-horned sculpin, spring for lamprey, ide, bream, perch and vimba bream, summer for three-spined stickleback, gudgeon and pikeperch, autumn for brown trout and Atlantic salmon.

From the cash desk you will get a list of Finnish fish species and a pencil and so you can mark those species you will see during your aquarium tour. Lists of the fish species are available with 19 different languages – maybe also with your mother language (русский, deutsh, nederlands, español, magyar, polski, čeština, eesti, norsk, english…) .
The aquarium tour takes about one hour and fifteen minutes. If you cannot go through the entire tour in one go, you can pop in at Café Meri Cafe Kristina to have some refreshments. After the tour, we recommend a visit to the Sea Shop.
