Watch the hypnotic shoals
Watch our large shoal of mackerels as they move around gracefully in the largest aquarium in Northern Europe.
The open sea
Here, you are in the middle of the North Sea with the large shoals of fish and the special and famous sunfish. Fish shoals need a lot of space, and that is why the Oceanarium is shaped like an ellipse on 22 x 33 metres. It contains 4.5 mill. litres of sea water, and this makes it Northern Europe’s largest aquarium.
The midwater between the sea floor and the surface is full of life. Here, the foundation of life in the sea begins.
The microscopic plants, the plankton algae, subsist on sunlight and get eaten by larger animals, which get eaten by larger fish – and so on.
In the midwater there are no hiding places, and that is actually the reason why the fish form shoals in this area of the sea. Herring, mackerel, horse mackerel and garfish do this – the fish simply hide between a large flock of peers.
In the spring, the mackerel and the garfish live near the Danish coasts where anglers are eager to catch them.
The Oceanarium is an impressive sight with its 4.5 mill litres of sea water and 2-3000 fish, including the sunfish.
No sunfish in the Oceanarium right now
We don’t have a sunfish in the Oceanarium at the moment. Our latest sunfish had bad kidneys and died in January.
Through the years we have successfully had sunfish in the Oceanarium most of the time, but we have had times without sunfish before, when we haven’t been able to get any new specimens.
The explanation is that we either get the sunfish from Danish waters – mostly during autumn – or alternatively get them small from Southern Europe.
As soon as our vendor from Southern Europe can deliver new sunfish, we will get them flown in to their new home. When that will be exactly, depends on the possibilities of finding them in the open seas of Southern Europe.
