Ponds, throughs and aquariums

Last changed: 08 June 2023

The Department of Aquatic Resources at Drottningholm has great facilities for research in freshwater such as ponds, tanks and aquariums. Do you want to perform experimental studies on fish or other aquatic organisms together with us? We have the infrastructure that enables research in aquatic environments.

Study aquatic organisms in ponds

The water in the eight ponds at Drottningholm comes from Lake Mälaren and has a water level that can be regulated. In these ponds researchers have studied fish behavior, effects of climate change and also conducted experiments to develop environmental analysis of the future. One of the eight ponds is 22 x 22 meters and seven ponds are 22 x 6 meters.

Study aquatic organisms in outdoor tanks

At Drottningholm there are also 20 outdoor tanks. At the moment, exciting experiments are underway in the tanks. We are investigating how we can reveal occurrences of pike by DNA analyzes of water samples. And one of our doctoral students recently studied the effects of climate change and brunification on plankton.

Study aquatic organisms in aquariums

The Department of Aquatic Resources at Drottningholm also has about 20 glass aquariums with sampling facilities next door. Water temperature and lighting in the aquariums can be regulated.

In the outdoor tanks, you can study organisms more closely, such as how fish communities are affected by climate change or whether eDNA can reveal the presence of pike. Photo: SLU.
