Summary

Ornate Rock Lobsters are found in north-eastern Australia, where stock is classified as sustainable. They are also found in northern WA, where stock status is negligible as a result of low catches.

Stock Structure

Ornate Rock Lobster populations in northern Queensland (managed by Queensland), the Coral Sea (managed by the Commonwealth) and the Torres Strait (managed by the Torres Strait Protected Zone Joint Authority) are thought to comprise a single North-Eastern Australia biological stock, as a result of mixing of larvae in the Coral Sea [Pitcher et al. 2005]. Water movement models in Torres Strait predict that larvae are likely to be transported into the Gulf of Carpentaria [Wolanski et al. 2013], indicating that the north-eastern stock encompasses this region as well. Stock assessments have not been carried out for the complete biological stock, but have been conducted on the various parts of it.

Although Ornate Rock Lobster is also present in northern Western Australia, biological stock structures in this region have not been studied and the relationship with the North-eastern Australian stock is unknown.

Here, assessment of stock status is presented at the biological stock level—North-Eastern Australia; and at the jurisdictional level—Western Australia.

Stock Status

Western Australia

Stock status for Western Australia is reported as Negligible as a result of low catches and fishing is unlikely to be having a negative impact on the stock. No commercial catch is taken from Western Australia. Very small catches are taken by charter operators (504 individuals reported as retained since 2000) and recorded in recreational surveys [Ryan et al. 2017].

Commonwealth - Commercial (Catch Totals) Catch data provided for Commonwealth and Queensland align with the 2017 calendar year. 

Commonwealth – Recreational (Management Methods) 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 (Management Methods) 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. In the Torres Strait, both commercial and non-commercial Indigenous fishing is managed by the Torres Strait Protected Zone Joint Authority (PZJA) through the Australian Fisheries Management Authority (Commonwealth); the Department of Agriculture, and Fisheries (Queensland); and the Torres Strait Regional Authority. The PZJA also manages non-Indigenous commercial fishing in the Torres Strait.

Commonwealth - Indigenous (Catch Totals) This specifically refers to non-commercial Indigenous catch. Commercial Indigenous catch in the Torres Strait is included under ‘commercial’

Northern Territory — Charter (Management Methods) In the Northern Territory, charter operators are regulated through the same management methods as the recreational sector but are subject to additional limits on license and passenger numbers.

Northern Territory – Indigenous (Management Methods) The Fisheries Act 1988 (NT), specifies that “…without derogating from any other law in force in the Territory, nothing in a provision of this Act or an instrument of a judicial or administrative character made under it limits the right of Aboriginals who have traditionally used the resources of an area of land or water in a traditional manner from continuing to use those resources in that area in that manner”.

Queensland – Indigenous (Management Methods) In Queensland, under the Fisheries Act 1994, Indigenous fishers are able 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.
