Come and take a look under the surface!

In our aquariums, you can discover underwater environments from coastal archipelago to open sea. The aquariums have different water systems, including both brackish water and water with relatively high levels of salinity. Come and take a look under the surface, and discover the incredible diversity of the Baltic Sea!

The jetty aquarium

The jetty aquarium features fish that live close to the coast. These are the fish that you might catch from a jetty: pike, zander, perch, roach, common rudd, crucian carp, tench and bream.

The schooling fish aquarium

Schooling fish swim in the free waters of the open sea. These are herring, and are known as Baltic herring if they live in the Baltic Sea.

The predatory fish aquarium

The majestic cod swim down at a depth of around 30 metres. See the round wreck, which represents a memorial to human history. Salmon, sea trout and eel also swim here. Shorthorn sculpin lie still in the wreck, and flatfish hide in the sand.

The cylinder aquariums

Fantastic jellyfish float in one of the cylinder aquariums, while mussels live on ropes in the other.

The habitat aquariums

The smaller aquariums showcase the various Baltic Sea environments that make this sea so unique.

On the shallow hard seabed, bladder wrack forms a forest that feeds and protects creatures. Here, stickleback and eelpout live a protected life.

On the deeper hard seabed, red algae and blue mussels live alongside fish such as cottids and small flatfish.

Few plants live on the deep soft seabed, so there is little shelter and the creatures that live here bury themselves instead – mussels, worms and perhaps the occasional small eel.

Even the tiniest of life can be seen in the smallest aquariums. Barnacles, mussels and all the different shrimps of the Baltic Sea.

The eelgrass meadow is an important habitat for many creatures, particularly the Baltic Sea’s pipefish. Did you know that they are related to the seahorse? The angular little broadnosed pipefish and the pretty straightnosed pipefish.

It is on the shallow, soft seabeds that plant life thrives. Many plants and algae share the sunlight. This is the perfect environment for young fish, such as small perch and common bleak.

Along the coast

The ‘Along the coast’ exhibition is all about people and the sea, and how we affect and depend on each other. Here, you can see what lies beneath the surface and along the beaches and coasts of the Baltic Sea.

The challenges of the Baltic Sea

In this part of the building, you can see how your own choices and those made by other people affect the future of the Baltic Sea. The exhibition highlights the three main environmental challenges faced by the Baltic Sea: eutrophication, environmental toxins and overfishing.

The laboratory

The Education Pavilion has classrooms, a laboratory and a film room, where all visitors are welcome. Various films are shown in the film room, including BalticSea2020 about life in the Baltic Sea.

Skansen is also working with Stockholm Water on a major project aimed at school pupils in Stockholm and Huddinge.

Our partners

The exhibitions will be created by a special knowledge council consisting of representatives from the Swedish University of Agricultural Sciences, Stockholm University, the BalticSea2020 Foundation and Skansen.
