Estimates of tag reporting rates are necessary in order to estimate tag-recovery rates and interpret taggingdata in terms of movement rates, exploitation rates and abundance. We describe a Bayesian frameworkfor the estimation of reporting rates for multiple fleets using coincidental tagging and catch data dis-aggregated by fish size, species, location and time. The method was applied to the data of the IndianOcean Tuna Tagging Programme (2006–2011) and tag seeding experiment of the Indian Ocean Tuna Com-mission (2004–2009). Reporting rates were estimated for 13 Indian Ocean tuna fleets. These estimatesvaried widely from 94% for the European Union purse seine fleet to less than 1% for fishing operationsof non-longline/non-purse seine fleets in the Eastern Indian Ocean. Generally, reporting rates were highcompared with estimates for tuna fisheries in other Oceans.
