Before you visit DNAlab we encourage you to collect your own eDNA sample from a fresh water site. This way, students will help monitoring the species and the biodiversity. Our experience shows that students get the most from the course when they collect the fresh water sample themselves.
How to collect eDNA
eDNA can be collected from most lakes, ponds and streams. The DNA-sample is collected by drawing up freshwater with a syringe and pressing the water through a filter. On the test site the water should be collected from different places and depths in order to collect as much different DNA as possible. To preserve the DNA, the filter is subsequently covered with ethanol and sent to the Museum of Natural History along with information on the test locality.
When and where do you collect eDNA?
The DNA can be collected from April to July. From Mid-April to early summer the fish and amphibians breed and there will be a maximum amount of eDNA present in the water, so this is the best time for collecting.
Consider your test site carefully! We are only looking for eDNA from chosen species. Check to see what species have been found on the site, and compare with the species we are looking for – in that way you will not collect in vain. You can look for the species’ Latin name on www.gbif.org/species or find more information on www.allearter.dk, and you can see the list of species we look for here.
