The four separate biological stocks of Australian Sardine are sustainable. It is caught commercially in WA, SA, VIC, TAS, NSW, southern QLD and Commonwealth waters using nets.
Stock Status Overview
|Western Australia||South Western Australia||Sustainable||Spawning biomass, exploitation rate, catch|
Australian Sardine off southern Australia is a meta-population [Whittington et al. 2008], with effective isolation of four separate biological stocks: the South-western (off Western Australia); Southern (off South Australia); South-eastern (off Victoria, Tasmania and southern NSW) and Eastern (off northern New South Wales and southern Queensland) Australian stocks [Izzo et al. 2017]. Recent evidence has confirmed the separation of the South Eastern Australia stock from the Eastern Australia stock [Sexton et al. 2018]. There is some evidence that the South-western and Eastern biological stocks each include two separate sub-components [Gaughan et al. 2002, Izzo et al. 2017]. The two sub-components off Western Australia were previously reported as two separate biological stocks, but these have now been merged into a single South Western Australia stock, which is managed as two management units.
Stock status for Australian Sardine is presented at the biological stock level—South Western Australia, Eastern Australia, South Eastern Australia and Southern Australia.
South Western Australia
The South Western Australia stock of Australian Sardine off Western Australia is comprised of two separate management units with some biological separation: West Coast and South Coast. Here, stock status assessments are presented for both units.
For the WA's West Coast, population modelling based on spawning biomass estimates obtained using the DEPM, catch-at-age and catch data, showed that by the mid-2000s the stock had recovered from the 1998–99 mass mortality caused by a herpes virus [Gaughan et al. 2008]. The annual exploitation rate in the mid-2000s was low at less than 5 per cent (around 400 t) of the estimated spawning biomass of approximately 25 000 t. Since then annual catches have remained below this level due to low fishing effort and are unlikely to cause the stock to become recruitment overfished.
For WA's South Coast, population modelling based on spawning biomass estimates obtained using the DEPM, catch-at-age and catch data showed a recovery from the 1998–99 mass mortality had been achieved by the mid-2000s [Gaughan et al. 2008]. The annual exploitation rate at that time was low at around 3 per cent (less than 3 000 t from an estimated spawning biomass of approximately 97 000 t), and the total annual catch has not exceeded 3 000 t since then.
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, the South Western Australia biological stock is classified as a sustainable stock.

|Total allowable catch|
|Licence (Recreational Fishing from Boat License)|
Commonwealth – Recreational The Australian Government does not manage recreational fishing in Commonwealth waters. Recreational fishing in Commonwealth waters is managed by the state or territory immediately adjacent to those waters, under its management regulations.
Commonwealth – Indigenous The Australian Government does not manage non-commercial Indigenous fishing in Commonwealth waters, with the exception of the Torres Strait. In general, non-commercial Indigenous fishing in Commonwealth waters is managed by the state or territory immediately adjacent to those waters.
Western Australia – Recreational (management methods) a Recreational Fishing from Boat License is required for use of a powered boat to fish or to transport catch or fishing gear to or from a land-based fishing location.
New South Wales – Indigenous (management methods) https://www.dpi.nsw.gov.au/fishing/aboriginal-fishing
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.
