Denis Rose grew up fishing for kooyang (eel) in the dams, weirs and rivers of Budj Bim, home to one of the world's oldest aquaculture systems. It was the 1970s when Gunditjmara Traditional Owners, like Rose, were only allowed to manage a small parcel of the World Heritage-listed site in south-west Victoria – a cemetery spanning two hectares. As a boy, he recalls admiring the intricate fish traps of generations past, but he had no say in how his ancestral home was cared for.
