We present a telemetry based method for simulating individual based movements, with a demonstration applied to Atlantic Bluefin tuna in support of operational modeling and spatially explicit stock assessments. The simulation model uses parameters derived from movements and positional uncertainty from groups of tagged individuals. We present the method and example output using a subset of the Large Pelagics Research Center (UMass Amherst) database of fish tagged off the Canadian Maritimes. Movement matrices that are constructed from size based simulations may be used directly in operational models already in use. Inclusion of tagging data from recent Eastern Atlantic and Mediterranean tagging efforts would facilitate mixing rate comparisons and provide a more robust estimate of population based movement metrics for stock assessment use.
