【 摘 要 】

A global literature review of recreational fishing survey methods determined potential cost-effective methods for monitoring recreational fishing in Commonwealth fisheries.National stakeholder workshops facilitated exchange of current knowledge of recreational fishing survey methodologies between state and Commonwealthgovernment agencies and non-government stakeholders. The workshops facilitated prioritisation of Commonwealth-managed species and fisheries that require monitoring,and potential methods to cost-effectively survey recreational fishers.Scenario modelling using stock assessments applied to data-rich and data-poor species demonstrated that the inclusion of recreational catch that exceeds 10% of commercial catch and age structure data can significantly influence assessments outcomes.An innovative and cost-effective approach to sampling hard-to-reach specialised recreational fishers in the absence of a sampling frame was developed using Respondent-Driven Sampling (RDS). RDS was the recommended method for obtaining the total recreational catch of Commonwealth-managed species when combined with a mark-recapture survey in a complemented “RDS-Recapture” survey design, after themethod undergoes thorough testing.
