Eastern School Prawn (2020)

Eastern School Prawn fisheries occur along the east coast of Australia. Stock status is sustainable in QLD, NSW and VIC.
Stock Status Overview
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 evidence for some minor genetic differentiation of Eastern School Prawn in the Tweed River and Noosa River from Eastern School Prawn in other estuaries, but estuaries within New South Wales appear to be generally 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. This status report 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), which closed at the end of March 2020 following a buy-out of all commercial netting licences, implemented to improve recreational fishing access by hook and line methods. Recreational catch is unknown.
Catch has generally increased since the early 2000s. A substantial increase in catch occurred between 2013 and 2016. Average annual catch since 2000/01 was 28.8 t. Although CPUE has undergone several large fluctuations every 3–5 years since 2000–01, this performance measure has generally shown an increasing trend, and has remained above the long-term average of 7.31 kg/shot since 2010. Declines in CPUE and catch may be due to periods where drifting seaweed obstructed nets.
On the basis of the evidence provided above, Eastern School Prawn in Victoria is classified as a sustainable stock.

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 – Recreational (Catch) Murphy et al. .
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.
