Fish

In the world’s largest cold-water aquarium , 50 alpine fish species – some of which are extremely rare – are kept in landscaped tanks. The 17 show tanks from 80 litres to 14,000 litres are arranged thematically and the inhabitants of certain types of water are presented. The temperature is lowered to 4 - 6°C in the winter months in line with the conditions in open waters, rising to 16 - 20°C in the summer and even reaching 22°C in the Lake Garda basin with heating rods. In the Alpenzoo, we exhibit the common nase, pike, catfish, wolffish, streber, grayling and brown trout.

Fish are among the most endangered creatures, and many species have become rare or disappeared due to pollution and the construction of waterways. The Alpenzoo aquarium has already produced some internationally recognised worldfirst breeds. In 2012, a large aquarium was opened in which typical fish species of the large Alpine rivers of the Danube system are on display. Watch the video about building the aquarium!
