Overhead aerial drone view of oyster farm racks at low tide, flying at a low altitude to be able to see the detail of the oyster racks and seaweed. Located in a tidal estuary in Sutherland, Scotland. the low tides enable workers to access the racks for turning the oysters as they grow. Oysters have been farmed for many hundreds of years using this method. Seaweed has grown around the metal lines of racks.
