The project uses baited and unbaited underwater cameras to monitor fish at six different locations in Sønderborg Bay. The locations are: two natural cobble reefs, two sandy seabeds (control sites) and two project sites (sandy seabeds where cobble reefs will be restored). Footage was collected from each of the sites, and again will be collected after the cobble reef restoration
Analyses examine if fish abundance and diversity change with cobble reef restoration. Data from the restored cobble reefs will be compared against the control sites and natural reefs. Data will be used to establish whether changes can be attributed directly to the reef restoration. Analyses will also reveal differences between fish species and fish body sizes recorded using baited and unbaited cameras.
Results from this study will be used to determine whether cobble reefs should be restored further to support fish diversity and abundance in coastal areas but also be applied to estimate the impacts of ongoing cobble excavation.
