Understanding the movement patterns of marine fishes is essential for identifying important habitats, assessing population connectivity, and informing effective fisheries management. However, determining movement patterns across broad spatial and temporal scales can be challenging using conventional scientific approaches. Citizen science provides an opportunity to expand the spatial and temporal coverage of data collection by engaging recreational fishers in research programs, generating both valuable data and greater stakeholder buy-in for research and management initiatives. The aim of this study was to investigate the movement patterns and connectivity between populations of sand flathead (Platycephalus bassensis) in Tasmanian waters using conventional tagging methods in conjunction with establishing a citizen scientist tagging program that would increase the quantity of tagged and recaptured fish. Between 2022 and 2026, over 10,000 sand flathead were tagged and released around Tasmania. At present, 60 fish have been recaptured (recapture rate: ~0.6 %), with time at liberty ranging from one day to three years. Preliminary findings from reported recaptures suggest that sand flathead show relatively restricted movements, with the majority of fish recaptured within hundreds of meters of the tagging and release location, irrespective of time at liberty. These findings are helping to improve the existing knowledge of sand flathead movements in Tasmania through increased spatial and temporal coverage. More broadly, the study demonstrates the value of collaboration between researchers and recreational fishers for collecting fisheries data over large spatial and temporal scales, especially for data poor species. Integrating citizen science into movement studies can complement traditional monitoring approaches, increase the quantity and spatial coverage of available data, and provide valuable insights to support fisheries management and conservation.
