Eastern School Prawn (2018)

Eastern School Prawn fisheries occur along the east coast of Australia. Stock status is sustainable in QLD and NSW and undefined in VIC.
Stock Status Overview
- Inshore Trawl Fishery (VIC)
Eastern School Prawn fisheries occur along the east coast of Australia, in Queensland, New South Wales and Victoria. Genetic work on the biological stock structure of this species is limited. There is some evidence for genetic differentiation between populations occurring from Tweed Heads northward (north of the Noosa River and Tweed River) and those from estuaries in New South Wales (estuaries within New South Wales were genetically homogenous ) [Mulley and Latter 1981]. No genetic information is available for Victorian populations.
As a result of uncertainty regarding the biological stock structure of Eastern School Prawn, assessment of stock status is presented at the jurisdictional level—Queensland, New South Wales and Victoria.
Eastern School Prawn is caught primarily as part of the commercial Inshore Trawl Fishery, mainly off the Gippsland coast of eastern Victoria. The Eastern School Prawn fishery is seasonal with effort concentrated in the warmer months. The assessment provided is focused on the Inshore Trawl Fishery, which represents 97 per cent of the total catch since 2000. The remaining catch was from the Gippsland Lakes Fishery (GLF) and bait fisheries. Recreational catch is unknown.
Catch has generally increased since the early 2000s. A substantial increase in catch occurred between 2013 and 2016, when catch increased from 16.82 t to a historical peak of 119.7 t in 2016, and then dropped to 27.04 t in 2017 [VFA Unpublished]. Drifting seaweed that severely obstructed nets substantially reduced in catch in 2017. Catch per unit effort (CPUE), as a proxy for biomass, has been quite variable with several large fluctuations occurring in the commercial inshore trawl fishery between 2008 and 2017. CPUE, however, has mostly been above the long-term average of 7.31 kg/shot since 2010.
On the basis of the evidence provided above, Eastern School Prawn in Victoria is classified as an undefined stock.

Queensland – Indigenous (Management Methods) Under the Fisheries Act 1994 (Qld), Indigenous fishers in Queensland are entitled to use prescribed traditional and non-commercial fishing apparatus in waters open to fishing. Size and possession limits, and seasonal closures do not apply to Indigenous fishers. Further exemptions to fishery regulations may be applied for through permits.
New South Wales – Commercial (Management Methods) Size limit – Prawn counts apply to commercial fisheries in NSW and serve as a proxy to size limit.
New South Wales – Indigenous (Management Methods) (a) The Aboriginal Cultural Fishing Interim Access Arrangement allows an Indigenous fisher in New South Wales to take in excess of a recreational bag limit in certain circumstances—for example, if they are doing so to provide fish to other community members who cannot harvest themselves; (b) The Aboriginal cultural fishing authority is the authority that Indigenous persons can apply to take catches outside the recreational limits under the Fisheries Management Act 1994 (NSW), Section 37 (1d)(3)(9), Aboriginal cultural fishing authority; and (c) In cases where the Native Title Act 1993 (Cth) applies fishing activity can be undertaken by the person holding native title in line with S.211 of that Act, which provides for fishing activities for the purpose of satisfying their personal, domestic or non-commercial communal needs. In managing the resource where native title has been formally recognised, the native title holders are engaged with to ensure their native title rights are respected and inform management of the State's fisheries resources.
Victoria – Indigenous (Management Methods) In Victoria, regulations for managing recreational fishing may not apply to fishing activities by Indigenous people. Victorian traditional owners may have rights under the Commonwealth's Native Title Act 1993 to hunt, fish, gather and conduct other cultural activities for their personal, domestic or non-commercial communal needs without the need to obtain a licence. Traditional Owners that have agreements under the Traditional Owner Settlement Act 2010 (Vic) may also be authorised to fish without the requirement to hold a recreational fishing licence. Outside of these arrangements, Indigenous Victorians can apply for permits under the Fisheries Act 1995 (Vic) that authorise fishing for specific Indigenous cultural ceremonies or events (for example, different catch and size limits or equipment). There were no Indigenous permits granted in 2017 and hence no Indigenous catch recorded.
