MSC-RBF Status

<60: Fail – High Risk

The striped trumpeter fishery scored < 60 in the MSC-RBF analysis, failing assessment with high risk of stock damage. The Productivity Susceptibility Analysis indicated this species is moderately productive – long-lived with a long generation time and potential to reach a large size, as well as being a highly fecund broadcast spawner. Striped trumpeter are highly susceptible to capture and damage by the fishery and are targeted in Tasmania across > 30% of the stock distribution. The Consequence Analysis showed a high risk of damage across all subcomponents of the fishery. A steadily declining trend in CPUE over time suggests striped trumpeter population size may be reduced within fished areas. The legal size limit is below the size at maturity and the age structure of landings is generally aging with a shortage of smaller, younger fishing indicating stock structure and recruitment dynamics are at high risk of continued damage.
