The associations were concerned that fishing restrictions might be imposed once the wind farm is operating along the route of the export cables connecting it to Eemshaven harbour in the north-east Netherlands.
Gemini, which is being developed by Typhoon Offshore, consists of two 300MW sites, each with a 110-kilometre 220kV cable that transports electricity to the substation in Eemshaven.
Permits for the project, located 55 kilometres north of the Dutch island of Schiermonnikoog, had to be amended due to the complete redesign of the project.
The permits explicitly state that third parties are allowed to continue using the area.
Rijkswaterstaat, the executive agency of the Dutch infrastructure and environment ministry, also stated it sees no reason to impose restrictions on fishing rights.
The project is expected to cost $3.8 billion and offshore construction is due to start in July 2014, with the aim of bringing the project online by end-2016.
In August, Northland Power, Siemens Project Ventures, Dutch offshore contractor Van Oord, Dutch utility HVC and Typhoon Offshore announced they would participate in Gemini as equity sponsors.
