Ocean Jacket (2020)
You are currently viewing a report filtered by jurisdiction. View the full report.
Ocean Jackets are found along the southern half of Australia, with sustainable stocks in NSW, SA and Commonwealth waters. Stocks in VIC are undefined, with limited information available. Stocks are negligible in TAS.
Stock Status Overview
Ocean Jackets are distributed along the southern half of Australia from Cape Moreton in Queensland around to North West Cape in Western Australia, including northern Tasmania [Kailola et al 1993]. Throughout their distribution, Ocean Jackets are found in many habitats. As juveniles they are found in estuaries and sheltered bays amongst seagrass beds of Zostera sp. and Posidonia sp. [Grove-Jones and Burnell 1991, Jones and West 2005]. Sub-adults and adults are found in different habitats such as rocky reefs, sandy–mud benthos, or sponge–coralline algae gardens in waters from 2–250 m [Grove-Jones and Burnell 1991, Hutchins 1999], where they are known to aggregate seasonally in large schools.
Little is known about the biological structure of the Ocean Jacket stock. Here, assessment of stock status is presented at the management unit level—Southeast Scalefish and Shark Fishery, Great Australian Bight Trawl Sector (Commonwealth); and at the jurisdictional level—New South Wales, Victoria, Tasmania and South Australia.
Victoria does not play a significant role in the management of Ocean Jacket which is not differentiated from other species of leatherjacket caught commercially or recreationally. Regardless of the actual species landed, the quantity of leatherjackets reported in Victoria in 2019 was relatively small (17 t) (~3 per cent) in comparison to catches in other jurisdictions, with the majority caught in traps within the Victorian Rock Lobster Fishery and by haul seine and mesh nets within the Corner Inlet Fishery. There is insufficient information available to confidently classify the status of this stock.
On the basis of the evidence presented above, Ocean Jacket in Victoria is classified as an undefined 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.

New South Wales – Recreational (Catch) Murphy et al. .
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.
