The last sampling to assess the impact of RAS Arctic char farm on biodiversity in Lierne, Norway was completed. The SAFE (SmartAqua4FuturE) team, with aim to evaluate impact of different aquaculture systems on local biodiversity was collecting samples from IMTA system in Ireland, pond farms in Poland, and a RAS farm in Norway. Now we will focus on conducting analysis of collected diatoms, benthic organisms and macroinvertebrates samples, and compare findings for the different aquaculture systems. The report will be published here once the results have been finalised.
