Design for the coat of arms of the district Ork from the City of Voerde (Niederrhein): „Vert, a springing salmon Argent with a tongue gules.“ 
The arms stand for the former fishermen in the village. The colours are derived from the arms of Spellen, where the village belonged to and symbolise the nature reserve too.
