2020/21 Striped Trumpeter Status (Released Dec 22)
|Summary||Following first recent records of young fish in biological samples after many years of suspected recruitment failure, evidence of population recovery of Striped Trumpeter is still lacking. Commercial catches are close to the historical low, but total levels of fishing pressure (commercial and recreational combined) might still prevent recovery, especially since the minimum size limit is below the estimated size at maturity. Newly introduced length-based assessment approaches indicate that stocks in the south-east coast region have been depleted below critical levels. More data are needed to clarify status and trends across the state.|

Striped Trumpeter is a relatively large and long-lived species. Juveniles inhabit shallow inshore reefs moving offshore with maturity to deeper exposed reefs ≤ 300 m (Edgar 2008). Striped Trumpeter are mainly caught offshore using handline, with some offshore dropline and inshore gillnet use. Management of Striped Trumpeter stocks has changed significantly over time, incorporating Tasmanian commercial operators and Commonwealth operators. Trip limits and a temporal closure during spawning are currently in place. However, the minimum legal size is below the size at maturity and the population of Striped Trumpeter has previously been found to be aging, suggesting that recruitment is limited, potentially because the spawning biomass of the population has been depleted.
