In this note, we present an approach which has been recently used to execute online the set of codes used for eastern blue_n tuna (BFT-E) stock assessment at ICCAT. We aim at discussing the possible interest of the approach to the IOTC Community for focusing on Indian ocean tuna and tuna-like stocks and running other assesment models such as Stock Synthesis 3 (SS3). In 2014, ICCAT BFT-E working group has been able to execute thousands of model runs by using parallelization of R and Fortran codes on a supercomputer. This approach has a lot of scienti_c bene_ts, in particular for better including the multiple sources of uncertainty in assessment results and associated scienti_c advice. However, very few participants would be able to reproduce it without speci_c technical skills. Since November 2015, a WebSite or VRE for Virtual Research Environment has been set up within the H2020 BlueBridge project to enable users to easily parametrize and execute various steps of the BFT-E stock assessment workow. By repackaging codes provided by ICCAT BFT-E working group, the same codes are now executable online. They can be parametrized, executed and edited by anybody from a simple web page and data outputs are delivered in standard data format. At this stage, this VRE comes with various collaborative Web Services: (i) a workspace to share documents or data, (ii) Web pages or RStudio server to process data online, and (iii) an automated report service to dynamically generate documents packaging these results. Such a collaborative environment enables
