The State Government has made the closure on taking Giant Australian Cuttlefish in the Upper Spencer Gulf permanent from May 1.
The Cuttlefish breeding gathering in the Upper Spencer Gulf is the only known event of its type for this species in the world, and the closure provides the best chance for the cuttlefish to grow in numbers.
The aggregation also serves as a significant tourism platform for communities around the Upper Spencer Gulf, and in particular Whyalla.
The closure was previously in temporary arrangements, which saw a 28 per cent increase in cuttlefish numbers compared to 2021.
