Bluethroat Wrasse are found on rocky reefs around south-eastern Australia. Catches in VIC, TAS and SA are considered to be sustainable. Catches in NSW are considered to be negligible.
Stock Status Overview
|New South Wales||New South Wales||Negligible||Catch|
Bluethroat Wrasse are found on rocky reefs around south-eastern Australia, including southern New South Wales, through Victorian and Tasmanian waters, to South Australia [Edgar 1997]. There is currently no information available regarding the biological stock structure of Bluethroat Wrasse in Australian waters. The species has a planktonic larval duration ranging from 44 to 66 days [Welsford 2003]. Once settled, Bluethroat Wrasse show a high degree of site fidelity [Edgar et al. 2004], suggesting that despite the potential for extensive dispersal of larvae by ocean currents exploited populations in each jurisdiction could represent different stocks. Thus, conservatively, assessment of stock status is presented at the jurisdictional level—New South Wales, Victoria, Tasmania and South Australia.
New South Wales
Stock status for the New South Wales stock is reported as Negligible due to historically low catches in this jurisdiction and the stock has generally not been subject to targeted fishing. The New South Wales commercial catch in 2012–19 averaged approximately 0.7 tonnes (t) per annum, and Bluethroat Wrasse is not a major component of recreational landings [West et al. 2015, Murphy et al. 2020]. Fishing is unlikely to be having a negative impact on the stock.

New South Wales – Recreational (Catch) Murphy et al. 
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.
Tasmania – Commercial (catch) Catches reported for the Tasmanian Scalefish Fishery are for the period 1 July to 30 June the following year. The most recent assessment available is for 2018/19.
Tasmania – Commercial (catch) A trip limit of 30 kg for landed dead Wrasse is in place unless fishers hold a Wrasse licence.
Tasmania – Recreational (management methods) A recreational licence is required for fishers using dropline or longline gear, along with nets, such as gillnet or beach seine. A minimum size limit of 300 mm is in place for all Wrasse species in Tasmanian waters. A bag limit of five fish and a possession limit of ten fish (all Wrasse species) are also in place.
Tasmania – Indigenous (management methods) In Tasmania, Indigenous persons engaged in traditional 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. For details, see the policy document "Recognition of Aboriginal Fishing Activities” (https://dpipwe.tas.gov.au/Documents/Policy%20for%20Aboriginal%20tags%20and%20alloting%20an%20UIC.pdf).
