There are five assessment units of Golden Snapper across Australia’s north. The WA, Regional NT, Gulf of Carpentaria and Eastern Australia assessment units are sustainable, whereas the Darwin Region management unit of the NT is classified as depleted.
Stock Status Overview
|Western Australia||Western Australia||Sustainable||
Golden Snapper is a moderately long-lived (i.e. 30 years), late-maturing species that can reach a length of one metre [Cappo et al. 2013]. They are broadly distributed throughout the tropical and sub-tropical Indo-West Pacific with juveniles spending several years in estuarine and inshore reef habitats before migrating to nearshore reef environments (to a depth of at least 80 m) as they near sexual maturity [Allen 1985, Kiso and Mahyam, 2003, Tanaka et al. 2011].
The distribution of this species within Australian waters extends from the Kimberley region in Western Australia, around the north of the continent to the southern Great Barrier Reef (around Rockhampton) [Travers et al. 2009]. A study of the stock structure of Golden Snapper across this range suggests that many functionally separate adult populations are present at a scale of tens of kilometres, although boundaries are unknown [Saunders et al. 2016].
Golden Snapper experience moderate to high harvest rates in some Australian fisheries (particularly those targeting adults of this late-maturing species), which can cause localised depletion. However, it is extremely difficult to collect relevant biological and catch-and-effort information to assess each adult population unit.
Here, assessment of stock status is presented at the jurisdictional level―Western Australia; and the management unit level―Darwin Region, and Regional Northern Territory (Northern Territory); Gulf of Carpentaria (Northern Territory and Queensland), East Coast (Queensland).
Golden Snapper are not a target species in the demersal fisheries of Western Australia, but are landed in small quantities as byproduct [Newman et al. 2020]. The total commercial catch of Golden Snapper in Western Australian demersal fisheries has been low and stable over the last 10 years (2010–2019), ranging from <100 kg–1.7 t per year, with a mean annual catch of 560 kg. Golden Snapper are also landed by recreational (~2 t annually) and charter fishers (~5 t annually), primarily in the Kimberley region of Western Australia. The catch of recreational and charter fishers is greater than the commercial catch of this species. The low catches of Golden Snapper in Western Australia are derived from a limited area compared to the wider distribution of the species. The above evidence indicates that the current level of fishing mortality is unlikely to cause the stock to become recruitment impaired. The above evidence also indicates that the biomass of Golden Snapper in Western Australia unlikely to be depleted and that recruitment is unlikely to be impaired.
On the basis of the evidence provided above, Golden Snapper in Western Australia is classified as a sustainable stock.

Western Australia – Active Vessels Data is unreportable as there were fewer than three vessels operating in the PFTIMF, PTMF and WL.
Western Australia – Recreational (management methods) A Recreational Fishing from Boat License is required for the use of a powered boat to fish or to transport catch or fishing gear to or from a land-based fishing location.
Western Australia – Recreational (Catch) Boat-based recreational catch is from 1 September 2017–31 August 2018. These data are derived from those reported in Ryan et al. 2019.
Western Australia – Indigenous (management methods) Subject to application of Section 211 of the Native Title Act 1993 (Cth), and the exemption from a requirement to hold a recreational fishing licence, the non-commercial take by Indigenous fishers is covered by the same arrangements as that for recreational fishing.
Northern Territory – Charter (management methods) In the Northern Territory, charter operators are regulated through the same management methods as the recreational sector but are subject to additional limits on license and passenger numbers.
Northern Territory – Indigenous (management methods) The Fisheries Act 1988 (NT), specifies that “…without derogating from any other law in force in the Territory, nothing in a provision of this Act or an instrument of a judicial or administrative character made under it limits the right of Aboriginals who have traditionally used the resources of an area of land or water in a traditional manner from continuing to use those resources in that area in that manner”.
