Stock Status Overview
|New South Wales||New South Wales||Negligible|
Also known as Shortfin Pike, Snook is distributed around southern Australia from Jurien Bay in Western Australia to southern Queensland, including northern Tasmania. It is usually found over seagrass beds and kelp reefs near the surface both in inshore and offshore waters of up to 20 m1–3. There is little 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.
New South Wales
Stock status for the New South Wales is reported as negligible due to low catches in this jurisdiction. New South Wales commercial catch in 2010–15 averaged less than 50 kg per year, and Snook is not a major component of recreational landings.
|Species||Longevity / Maximum Size||Maturity (50 per cent)|
|Snook||20 years; 1100 mm TL||420 mm TL|
Distribution of reported commercial catch of Snook
|New South Wales|
a 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.
b Western Australia – Recreational (management methods) In Western Australia, a recreational fishing from boat licence is required to take finfish from a powered vessel.
c Victoria – Indigenous (management methods) In Victoria, regulations for managing recreational fishing are also applied to fishing activities by Indigenous people. Recognised Traditional Owners (groups that hold native title or have agreements under the Traditional Owner Settlement Act 2010 [Vic]) are exempt (subject to conditions) from the requirement to hold a recreational fishing licence, and can apply for permits under the Fisheries Act 1995 (Vic) that authorise customary fishing (for example, different catch and size limits or equipment). The Indigenous category in Table 3 refers to customary fishing undertaken by recognised Traditional Owners. In 2015, there were no applications for customary fishing permits to access Snook.
d Victoria – Indigenous (management methods) Subject to the defence that applies under Section 211 of the Native Title Act 1993 (Cth), and the exemption from a requirement to hold a Victorian recreational fishing licence, the non-commercial take by indigenous fishers is covered by the same arrangements as that for recreational fishing.
e Tasmania – Indigenous (management methods) In Tasmania, aborigines engaged in aboriginal 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. Additionally, recreational bag and possession limits also apply. If using pots, rings, set lines or gillnets, aborigines must obtain a unique identifying code (UIC). The policy document Recognition of Aboriginal Fishing Activities for issuing a Unique Identifying Code (UIC) to a person for Aboriginal Fishing activity explains the steps to take in making an application for a UIC.
f Western Australia – Recreational (catch) Western Australia boat-based recreational catch from 1 May 2013–30 April 2014.
g Victoria – Commercial (catch) Snook is not differentiated from Longfin Pike caught in Victorian commercial fisheries.
Effects of fishing on the marine environment
- Trolling was considered a low risk to Snook populations in the 2012–13 ecological risk assessment (ERA) of the Tasmanian Scalefish Fishery8. It was also considered to have a negligible impact on associated by-product and bycatch species as capture is minimal and most are released alive and healthy. Trolling was also considered to be of negligible risk to threatened, endangered and protected (TEP) species as interactions are rare. While ‘Pike’ is an important predator, it is unlikely that the current level of fishing pressure is high enough to impact the ecosystem structure and associated marine environment.
- Mesh netting was considered a high risk to Snook populations in the 2012–13 ERA of the Tasmanian Scalefish Fishery8. This is due to the significant overlap between this sub-fishery and the species’ distribution along the north coast of Tasmania. Snook is also highly selected by the mesh size used and is usually retained. Some TEP species were also considered medium risk from mesh netting including: marine mammals, seabirds and chondrichthyans due to their low productivity and post release survival. Importantly, cormorants were ranked high risk, due to the increased likelihood of interactions occurring caused by gear being deployed in shallower waters. In reality, mesh net effort in northern Tasmania is at such a low level that the risk to these species is likely lower than identified in the ERA.
- The Victorian Bays and Inlets commercial fishers have adopted environmentally responsible fishing practices9. It is likely that fishing activities have minimal impact on the environment.
Environmental effects on Snook
- The impact of environmental factors on Snook is unknown. However, their abundance and distribution are likely to be affected by environmental conditions, including ocean currents, temperature and salinity, which may influence habitat suitability, food availability and recruitment.
