Hunting on the water is a natural way of life in the Tiwi Islands.
Mantiyupwi clan member Les Morris Ullungurra says they're looking for new ways of harvesting traditional foods - starting with the Black-lip oyster.
It's a delicacy which grows wild on rocks fringing the two main islands of Melville and Bathurst.
Now they're being farmed in cages, floating offshore.
