On 28 March 2013, the state government introduced a temporary ban on fishing for cuttlefish in the northern Spencer Gulf for the 2013 breeding season. Fisheries Minister Gago announced that research into the reasons behind the 90% decline in the cuttlefish population had ruled out commercial fishing as a cause, but was otherwise inconclusive, and that further areas of Spencer Gulf would be closed in 2014. The ban has been extended, and will remain in place until 15 February 2017. The closed area is defined as all Spencer Gulf waters north of Wallaroo and Arno Bay.
