Royal Red Prawn is widely distributed, occurring in depths of 350 m to 550 m in the Indian and western Pacific oceans. In Australia, the main geographic distribution is from Sydney on the east coast around southern Australia to Perth on the west coast, with some occurrence as far north as Moreton Bay, Queensland [Kailola et al. 1993]. Catches have been recorded off New South Wales, Queensland and Western Australia between latitudes 10°S and 36°S [ABARES 2018]. On the east coast, Royal Red Prawn is mainly distributed between 26°S and 36°S with few records at 40°S. Commercial catches are mainly taken between Sydney and Ulladulla [Rowling 1995]. Little is known of the stock structure in eastern Australia and the northern limit of the stock is unknown, but is considered to lie north of the current boundary of the fishery at Barrenjoey Point, 35° 35’S [Rowling 1995].
Off New South Wales, catches have been recorded between 275 m and 820 m, with most catches taken between 365 m and 550 m [Rowling 1995]. According to logbook catches from the Commonwealth Southern and Eastern Scalefish and Shark Fishery (SESSF) almost all the commercial catch was taken from 350 m to 550 m depth with 90 per cent of the catch from the 400 m to 499 m [Baelde 1995, Tilzey 1994]. There is evidence of a size related latitudinal distribution with larger prawns (spawners) towards the northern end of the range and juveniles (< 20 mm length) towards the south [Baelde 1992, Rowling 1995, Tilzey 1994]. Royal Red Prawn have two spawning seasons each year, resulting in two annual recruitment pulses, in February-April and again in July-August [Tilzey 1994, Rowling 1995]. They are relatively slow growing and longer lived than shallow water penaeid prawns [Tilzey 1994].
Here, assessment of stock status is presented at the biological stock level—South Eastern Australia; and jurisdictional level—Queensland.
Royal Red Prawn occur in Queensland waters [Potter and Dredge 1895], although little is known about their distribution or potential biomass. The species has remained mostly unfished since 1991 with a peak catch of 30 t and 122 days effort in 1989, and little catch thereafter [Helidoniotis et al. 2018]. The commercial harvest of Royal Red Prawn only began again in 2016 but catch and effort remain very low at less than 100 kg catch and three days effort in 2018-19 [QFISH 2020]. While the current level of fishing pressure is unlikely to cause the stock to become recruitment impaired, there is insufficient information available to confidently classify the status of this stock.
On the basis of the evidence provided above, Royal Red Prawn in Queensland is classified as an undefined stock.
South Eastern Australia
Royal Red Prawn in Commonwealth fisheries is managed as a Tier 4 stock under the Southern and Eastern Scalefish and Shark Fishery (SESSF) Harvest Strategy Framework [AFMA, 2019]. Haddon & Sporcic  informed the management of the stock for the 2019–20 fishing season.
The Tier 4 analysis by Haddon and Sporcic , indicated that the standardised CPUE for the recent four years to 2016 was varying around the target reference point. The RBC estimated by Haddon and Sporcic  was 431 t. Some concerns about using a standardised CPUE for this stock have been expressed because targeting of Royal Red Prawn is market driven [Morison et al. 2013] and such practices may influence CPUE. However, the above evidence indicates that the biomass of this stock is unlikely to be depleted and that recruitment is unlikely to be impaired.
Landed catch in the Commonwealth Trawl sector of the SESSF was 164 t in the 2019–20 fishing season (147 t in 2018-19 fishing season). Discards have been estimated to be 17.5 t based on the weighted average of the previous four calendar years (2015 to 2018) [Burch et al., 2019]. New South Wales catch data are considered to be confidential due to the small number of operators, but the sum of the landed catch (SESSF and New South Wales catch) and discards was well below the RBC of 431 t calculated in the 2017 analysis. The above evidence indicates that the current level of fishing mortality is unlikely to cause the stock to become recruitment impaired.
On the basis of the evidence provided above, the South Eastern Australia biological stock is classified as a sustainable stock.

Commonwealth – Commercial (Management Methods/Catch) Data provided for the Commonwealth align with the Commonwealth Southern and Eastern Scalefish and Shark Fishery for the 2018-19 financial year.
Commonwealth – Recreational The Commonwealth does not manage recreational fishing in Commonwealth waters. Recreational fishing in Commonwealth waters is managed by the state or territory immediately adjacent to those waters, under its management regulations.
Commonwealth – Indigenous The Australian government does not manage non-commercial Indigenous fishing in Commonwealth waters, with the exception of Torres Strait. In general, non-commercial Indigenous fishing in Commonwealth waters is managed by the state or territory immediately adjacent to those waters.
