Outdoor ponds 400 m²

Six natural gravel-bed ponds of 400 m2 in size and a maximum water depth of 2 m are available for studies focusing on lentic species. These ponds can maintain fish populations all the year round.  A clear indication of the ponds' qualified test site potential is the research conducted on the susceptibility of fish individuals to harvesting, and further the effects of harvesting-induced selection on fish populations.
