Jackass Morwong is a large, long-lived species associated with exposed sand and silt habitat from central Queensland to southern Western Australia, including Tasmania (Edgar 2008). Abundance of Jackass Morwong is low in Tasmanian waters and, as such, the species is not targeted in Tasmania, but landed as by-product of gillnetting. Commonwealth assessments concluded that Jackass Morwong stocks were Overfished from 2008 to 2010, but stocks have since been classified as Sustainable (Patterson et al. 2021). There is a significant recreational fishery for Jackass Morwong in Tasmania, primarily targeting the species using gillnet gear.
