The research for academic journal Environmental Research Letters looked at the effect on fisheries at the site where 36 Vestas turbines were built in 2006 between 10km and 18km off the Dutch coast.
It was the first offshore wind farm to be built in the North Sea waters of the Netherlands. The area had previously been heavily fished.
An increase in sole, whiting and striped red mullet was recorded as the fish found shelter inside the wind farm, while mussel larvae attached themselves to the monopile foundations of the turbines.
And over the two year investigation period more porpoise clicks were recorded inside the wind farm than outside.
However, the report suggested that some bird species might also be deterred by the presence of an offshore wind farm.
