Stock Structure

John Dory inhabits coastal and continental-shelf waters around most of Australia. The majority of the catch is taken along the eastern and southern coasts, with a small catch reported from the Northern Territory Timor Reef Fishery. The main distribution stretches from Moreton Bay in southern Queensland south and west to Cape Cuvier in Western Australia, with a limited distribution in eastern Bass Strait. John Dory are solitary as adults [Stergiou and Fourtouni 1991] and are reported to inhabit depths from 5 m to 360 m. Most of the catch is taken in 50–200 m depth, with over half of the catch is taken at 100–149 m depth [May 1986, Williams 1990 (both cited in Kailola et al. 1993), Staples 1995]. The stock structure of this species off Australia is poorly understood [Staples 1995]. Along the eastern and south eastern coasts, John Dory is considered to constitute a single biological stock for assessment and management purposes.

Here, assessment of stock status is presented at the biological stock level—South Eastern Australia, and at the jurisdictional level—Western Australia, Northern Territory.

Stock Status

Northern Territory

Stock status for the Northern Territory is reported as Negligible due to catches only being reported in 2014–18 in the Timor Reef Fishery. The maximum annual catch during this time was < 0.4 t and the stock has not been subject to targeted fishing by any sector. Fishing is unlikely to be having a negative impact on the 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

Queensland –  Please refer to https://www.daf.qld.gov.au/business-priorities/fisheries/traditional-fishing for information on traditional fishing in Queensland

New South Wales  Indigenous and Recreational catch estimates of “Negligible” are based on zero catches of John Dory recorded during the 2017-18 survey of the catch by 1-3 year NSW recreational licence holders [Murphy et al. 2020]

New South Wales - Indigenous  Customary Fishing Management Arrangements. See https://www.dpi.nsw.gov.au/fishing/aboriginal-fishing

Victoria – Indigenous (Management Methods) A person who identifies as Aboriginal or Torres Strait Islander is exempt from the need to obtain a Victorian recreational fishing licence, provided they comply with all other rules that apply to recreational fishers, including rules on equipment, catch limits, size limits and restricted areas. Traditional (non-commercial) fishing activities that are carried out by members of a traditional owner group entity under an agreement pursuant to Victoria’s Traditional Owner Settlement Act 2010 are also exempt from the need to hold a recreational fishing licence, subject to any conditions outlined in the agreement. Native title holders are also exempt from the need to obtain a recreational fishing licence under the provisions of the Commonwealth’s Native Title Act 1993.
