Southern Shortfin Eel occurs in coastal streams of eastern Australia, from southern QLD to the Murray River (SA). A distinct sub-species is also found in New Zealand and islands of the western Pacific. There is currently no cross-jurisdictional stock assessment for Southern Shortfin Eel in Australia, so this assessment is presented at the jurisdictional level. Southern Shortfin Eel is classified as undefined in QLD and NSW, and sustainable in VIC and TAS.

Stock Structure

Southern Shortfin Eel is widespread in coastal streams of south-eastern Australia, from the Pine River in southern Queensland to the Murray River in South Australia, including Tasmania. The species also occurs in New Zealand and western Pacific Islands [Beumer 1996, Allen et al. 2002]. Genetic studies indicate that Shortfin Eel represents two geographically separate subspecies; Anguilla australis australis in Australia and Anguilla australis schmidtii in New Zealand and western Pacific islands [Shen and Tzeng 2007, Arai 2016]. As there is currently no cross-jurisdictional stock assessment undertaken for the shared stock, assessment of stock status is presented here at the jurisdictional level—New South Wales, Queensland, Tasmania and Victoria.

Stock Status


The Victorian Eel Fishery is comprised of both Longfin Eel and Southern Shortfin Eel, which have different but overlapping distributions in estuarine and freshwaters east and south of the Great Dividing Range. Commercial fishing is generally confined to lower and estuarine reaches of waters that are open to fishing and predominantly targets migrating eels.

The Victorian Southern Shortfin Eel Fishery, which is managed as one stock, supports both recreational and commercial fisheries. The status of the Victorian Southern Shortfin Eel fishery has been evaluated using catch and nominal catch per unit effort (CPUE) for the commercial eel fishery. 

Since 1979–80 annual catch has been highly variable. Throughout the 1980s and 1990s annual catch ranged from 131–310 t, but thereafter declined considerably to an historic low of 32 t in 2010–11.  This decline is attributed to the Millennium Drought (2000–2011), which ended following emergence of La Niña weather conditions. Since then annual catch has continued to vary, averaging 58 t per year with a low of 36 t in 2016–17 and a high the following year of 84 t.

CPUE during normal fyke net fishing operations, as opposed to large scale removals of many tonnes of stocked eels with seine nets ahead of impending drought, has ranged from 1.5 to 4.0 kg/net-day with an overall average of 2.5 kg/net-day since 1980. This implies that when environmental conditions are favourable the performance of the fishery is reasonably stable.

Juvenile and undersized eels (elvers and “snigs”), known as “restock”, are netted from coastal rivers and relocated to designated culture lakes (confined lakes and impoundments) in inland western Victoria for on-growing to market size under an Aquaculture Licence. This practice, which commenced in the 1960s, is dependent on access to restock eels. Productivity from culture lakes is highly susceptible to short and long term and seasonal environmental variations, particularly drought [Victorian Fisheries Authority 2017]. Since 2003 restock Southern Shortfin Eels have represented on average 15 per cent (2.5–48 per cent) of the total annual catch. 

There is no long-term estimate of recreational harvest of Southern Shortfin Eel in Victoria but it is believed to be very low. In recent surveys of recreational fishing licence holders, <0.4 per cent of anglers fishing in rivers and lakes preferred to catch eels and just 2.6 per cent indicated their favourite fish to catch was eel [Australian Survey Research 2012, Australian Survey Research Pty Ltd 2018].

Eel is an important resource for some Aboriginal communities.  The use of fish traps, channels and aquaculture systems (ponds and dam walls) in western Victoria dates back tens of thousands of years [Head 1989, Richards 2011].  However, no quantitative estimates of the Aboriginal harvest of eels from Victorian waters are available.

The Victorian Southern Shortfin Eel Fishery is managed using a range of input controls and at least thirty per cent of all connected rivers, creeks and streams with a common opening to the sea are closed to commercial fishing. The eel fishery is subject to strong environmental drivers that can severely reduce productivity. Nonetheless, 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 also 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, Southern Shortfin Eel in Victoria is classified as a sustainable stock.

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.
