Bluethroat Wrasse
Notolabrus tetricus
2020/21 Bluethroat Wrasse Status (Released Dec 22)
| Stock Status | SUSTAINABLE | ||
| Summary | Catches, effort and catch rates of Wrasse have remained relatively stable for almost a decade, providing little reason for concern that the current level of fishing mortality is too high. Uncertainty remains over levels of potential localised depletion, and about the size of the catch taken by rock lobster fishers and used for bait. | ||

Background
Two species of Wrasse are taken commercially in Tasmanian waters: Notolabrus tetricus (Bluethroat Wrasse) and Notolabrus fucicola (Purple Wrasse). The two species have only been distinguished in catch data since 2007, despite their different size, depth, and tendency to be captured by different gear. Both species are protogynous hermaphrodites, with all individuals beginning life as females and some undergoing a sex inversion after maturity. Both Wrasse are reef-associated and are targeted primarily using fish traps (mainly Purple Wrasse) and handline (mainly Bluethroat Wrasse). Live fish trade is the main interstate market for Wrasse, while the local market comprises dead Wrasse for rock lobster bait and some human consumption. The live-fish fishery has accounted for > 90% of total reported catches since 2001/02 and there is no significant recreational fishery for these species.
