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

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. Here, assessment of stock status is presented at the jurisdictional level—Western Australia, New South Wales, Victoria, Tasmania and South Australia.
Stock Status
Western Australia
In Western Australia, Snook and Pike (Family: Sphyraenidae) are very minor components of commercial and recreational catches. Commercially, the highest catches of Snook were reported from the Wet Line sector on the South Coast (WA), with catches being less than 3 tonnes (t) prior to 2014 and less than 5 t in subsequent years. The annual WA charter catch for this species has been < 1.0 t since 2001. The estimated statewide boat-based recreational catch of 3,470 fish (+/- se 1,773) in 2020–21 [Ryan et al. 2022] is higher than the previous 2017–18 estimate but similar to the 2011–12 estimate. Snook are not targeted by any sector and there is no evidence that catches have fluctuated greatly through time.
All assessments in Western Australia are undertaken using a weight of evidence approach. For Snook, the lines of evidence considered included: catches, catch distribution, effort, vulnerability assessment (Productivity Susceptibility Analysis) and stock reduction analyses (Catch-MSY) [Haddon et al. 2018]. Catch-MSY forward projections (based on recent catch levels) infers that the biomass remains well above the point of recruitment impairment (BMSY limit reference point) under current management arrangements. In addition, in Western Australia, all finfish species are allocated to a species suite [Newman et al. 2018]. Snook is part of the nearshore suite in temperate waters of Western Australia. Indicator species are identified, based on biological vulnerability and frequency of capture and include King George Whiting, Australian Salmon and Sea Mullet. As these indicator species have been assessed as sustainable under current management arrangements and given the very low Snook catches and the weight of evidence assessment, the current risk level for the Western Australia Snook stock is estimated to be “Low”. Therefore, current status of the Snook stock in Western Australia is “Acceptable-Sustainable” and no new management is required.
The available information indicates that the biomass is not depleted and the current level of fishing mortality is unlikely to lead to recruitment impairment.
On the basis of the evidence provided above, Snook in Western Australia is classified as a sustainable stock.

Western Australia – Recreational (catch). Western Australia boat-based recreational catch from 1 September 2020–30 August 2021 [Ryan et al 2022]. 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://fishing.tas.gov.au/Documents/Policy%20for%20Aboriginal%20tags%20and%20alloting%20an%20UIC.pdf).
