Stock Structure

Yelloweye Mullet is widely distributed along the southern coast of Australia, from Murchison River in Western Australia to Hunter River in New South Wales, and around Tasmania1. Yelloweye Mullet typically occur in schools in nearshore marine waters from the intertidal zone to depths of at least 10 m, and are often abundant in estuaries and the lower reaches of rivers2,3.

The biological stock structure of Yelloweye Mullet in Australia is not well understood. It has been suggested that there are two biological stocks—Western and Eastern—based on morphological differences4,5. However, further studies are required to confidently define biological stock delineation for this species.

Here, assessment of stock status is presented at the jurisdictional level—Western Australia, Victoria, Tasmania and South Australia.

Stock Status


In Tasmania, Yelloweye Mullet is caught mainly using beach seine nets, with annual commercial catches peaking at around 22 t in 1999–2000, before declining to less than 5 t over the past decade10. Targeted beach seine effort on this species has been stable at low levels since 2005–06, while nominal catch rates have remained relatively stable over time with a sharp increase in 2012–13, before declining again to average levels. Recreational fishers in Tasmania target Yelloweye Mullet using mesh nets and seine nets however, increased regulation of recreational netting over the past decade has resulted in a general reduction catch and effort, with around 1.7 t taken by netting in 2009–1011. State-wide recreational catch of Yelloweye Mullet was estimated at 7.1 t in 2012–13, which included all fishing methods12. Yelloweye Mullet are most abundant in estuarine habitats13, where netting is prohibited or restricted, thereby providing a high degree of protection for the species throughout most of its range in Tasmania. The above evidence indicates that the biomass of this stock is unlikely to be recruitment overfished, and that the current level of fishing pressure is unlikely to cause the stock to become recruitment overfished.

On the basis of the evidence provided above, Yelloweye Mullet in Tasmania is classified as a sustainable stock.

a Tasmania – Recreational (fishing 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 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 Yelloweye Mullet.
c 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.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.

Effects of fishing on the marine environment

  • Yelloweye Mullet are targeted by commercial fisheries using mainly mesh (gill) nets and hauling nets. These activities are considered to pose a low risk to the environment18,19.
  • Some bycatch may be expected from mesh (gill) nets used to target Yelloweye Mullet, including the capture of undersized individuals of some species20. However, these nets are highly selective in their ability to capture target species18.

Environmental effects on Yelloweye Mullet

  • Estuaries provide important habitat for Yelloweye Mullet through its life history. The availability of habitat and trophic resources for Yelloweye Mullet in estuaries is largely dependent on seasonal freshwater inflows from inland catchment areas.
  • The impact of environmental factors on the spawning dynamics and recruitment of Yelloweye Mullet is unknown.
