30 x MOSES in Haringvliet (the Netherlands)

In June 2019 ReefSystems has installed 3 x 10 MOSES modules in Haringvliet (see video below). The pilot installations have been executed in collaboration with Sportvisserij Nederland, Bureau Waardenburg and the Marine Animal Ecology group from the Wageningen University & Research (WUR). The structures are placed in three locations with different environmental factors: 10 in salt water, 10 in sweet water and 10 in brackish water. Biodiversity has declined at Haringvliet, since the installation of the Haringvliet sluizen. Creating habitats in these areas is very important to restore the local ecosystems. Check out the first research results below!


Results

Researchers from Wageningen University & Research are periodically monitoring the installations with eDNA. With this modern molecular technique, watersamples are analyzed to identify the biological material that different fish species have left behind in the water the past 24 hours. The samples are compared with samples taken from several distances of the reefs to compare the results.

 

The latest eDNA samples have proved the presence of 17 different fish species around the artificial MOSES-reef. These positive results convinced Rijkswaterstaat and Port of Amsterdam to start a collaboration with us. Together we are currently working on a new project, where 100 modules are installed in three different locations in the North Sea Channel.
