Test Facility

Aquatic Outdoor Test Facility

We provide 5 lentic mesocosm systems (ponds) with a capacity of up to 120 mesocosms and 1 lotic mesocosm system (streams) with 19 mesocosms.

The advantages of our test facility:

  • A high diversity and sound abundances of a broad range of aquatic species.
  • The facility is surrounded by a buffer zone of meadows – no contamination by agriculture pratice.
  • The source of sediment and water (naturalized ponds) of the mesocosms is located at the test facility – best conditions for recolonisation.


Our laboratory infrastructure features modern technique like delayed fluorescence spectroscopy (algae analysis), climate chambers and equipment for microbiological work.

We focus on modified and flexible experimental set-ups for new or special questions. Non-standard studies with different test organisms are our most frequent indoor applications.
