Pale Octopus is distributed from the Great Australian Bight around TAS to southern NSW. Stocks are classified as depleting in Tasmania, negligible in NSW and SA, and undefined in VIC.
Stock Status Overview
|South Australia||South Australia||Negligible|
Pale Octopus is distributed from the Great Australian Bight around Tasmania to southern New South Wales. There is evidence to suggest that Pale Octopus shows complex biological stock structure, with a number of discrete subpopulations in Bass Strait (less than 100 km apart) due to limited dispersal and isolation by distance [Doubleday et al. 2008, Higgins et al. 2013]. However, further information is required to confirm the overall stock structure across southern Australia. Here, assessments of stock status are presented at the jurisdictional level—New South Wales, Victoria, Tasmania and South Australia.
Stock status for Pale Octopus in South Australia is reported as Negligible due to historically low catches in this jurisdiction and the stock has generally not been subject to targeted fishing. South Australia’s commercial catch of Pale Octopus over the past 20 years has averaged 10.7 t per annum, and the species is not a major component of recreational landings. Fishing is unlikely to be having a negative impact on the stock.

|Pale Octopus||1.5 years, 1200 g||Females 473 g, Males < 250 g|
Victoria – Commercial (catch) Pale Octopus is not differentiated from other octopuses caught in Victorian commercial fisheries.
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.
Tasmania – Commercial (catch) Catches reported for the Tasmanian Octopus Fishery are for the period 1 March to end of February the following year. The most recent assessment available is for 2018/19.
Tasmania – Commercial (management methods) A general possession limit of 100 kg of octopus per day (all species combined) is in place for holders of a fishing licence (personal) and a scalefish licence. This limit does not apply to Tasmanian Octopus Fishery licence holders operating in northern Tasmania.
Tasmania – Recreational (management methods) In Tasmania, a recreational licence is required for fishers using rock lobster pots, along with nets, such as gillnet or beach seine. A bag limit of five octopus and a possession limit of ten octopus (all species combined) is in place for recreational fishers.
Tasmania – Indigenous In Tasmania, Indigenous persons engaged in traditional fishing activities in marine waters are exempt from holding recreational fishing licences, but must comply with all other fisheries rules as if they were licensed.
