Summary

Also known as Shortfin Pike, Snook is distributed around southern Australia. The status of stocks in SA, TAS and WA is considered to be sustainable. Catches of Snook in NSW are considered to be negligible. In VIC, stock status is undefined.

Stock Structure

Snook, also known as Shortfin Pike, is distributed around southern Australia from Jurien Bay in Western Australia to southern Queensland, including Tasmania. Snook are found over seagrass beds and kelp reefs near the surface both in inshore and offshore waters of up to 20 m depth [Bertoni 1995, Edgar 2008, Gormon et al. 2008]. There is no information available on the stock structure of Snook in Australian waters. Thus, assessment of stock status is presented at the jurisdictional level—Western Australia, New South Wales, Victoria, Tasmania and South Australia.

The most recent assessment of Snook was completed in 2020 [Steer et al. 2020]. The primary indicators of biomass and fishery status are targeted catch rates using troll lines and hauling nets. During the assessment period, catch rates were highly variable, without being indicative of any long-term trend. Annual catches of Snook in South Australia's commercial multi-species, multi-gear and multi-sectoral Marine Scalefish Fishery (MSF) ranged between 40 and 113 t from 1999–00 to 2018–19, with 41 t landed in 2018–19. Annual nominal catches of Snook in the South Australian Charter Boat Fishery have ranged betweeen 5 376 and 1 510 fish between 2007–08 and 2018–19 [Rogers et al. 2020]. An estimated 126 t of Snook was landed by the recreational sector in 2013–14 [Giri and Hall 2015], which represents the potentially largest source of fishing mortality. The above evidence indicates that the biomass of this stock is unlikely to be depleted and that recruitment is unlikely to be impaired. Furthermore, 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, Snook in South Australia is classified as a sustainable stock.

Western Australia – Recreational (catch) Western Australia boat-based recreational catch from 1 September 2017–30 August 2018 [Ryan et al 2019]. Shore based catches are largely unknown.

Western Australia – Recreational (management methods) In Western Australia, a recreational fishing from boat licence is required to take finfish from a powered vessel.

Victoria – Commercial (catch) Snook is not differentiated from Longfin Pike 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 – Recreational (management methods) In Tasmania, a recreational licence is required for fishers using dropline or longline gear, along with nets, such as gillnet or beach seine.

Tasmania – Commercial (catch) Catches reported for the Tasmanian Scalefish Fishery are for the period 1 July to 30 June the following year. The most recent assessment available is for 2018/19.

Tasmania – Indigenous (management methods) 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. For details, see the policy document "Recognition of Aboriginal Fishing Activities” (https://dpipwe.tas.gov.au/Documents/Policy%20for%20Aboriginal%20tags%20and%20alloting%20an%20UIC.pdf).
