Importance of reef habitats for fish, harbor porpoises and fisheries management (RALFISK) (39401)

Project Details


This project investigates the importance of reef habitats for fish, harbor porpoises and fisheries management. A cobble reef was deployed and investigated using a before-after-control-impact approach. The sites included the deployed cobble reefs, control sites and areas with natural cobble reefs. All locations were monitored using baited and unbaited underwater cameras with a particular interest in the mobile fauna. The study was carried out in collaboration with a local NGO (Als Stenrev) with a great interest in restoring rocky reefs. The study was completed in an area where rocky reefs were removed from the seabed and used for the construction of harbors and bridges between 1900-2000. The project targeted cobble reefs because cobble is still being extracted from the seabed in dedicated zones of the Danish waters.
