In this paper, we further discuss known issues, achievements and challenges to improve IOTC resources management and we attempt to identify opportunities brought by Open Science principles to face them. For a regional organization like IOTC, we recommend to promote and implement these good practices internally at the Secretariat level as well as externally to expose and disseminate resources though multiple channels for the sake of users (CPCs or wider audience). Such practices appear to be instrumental as well when reusing external contributions or when sub-contracting or delegating tasks to CPCs. We also showcase how such good practices can be implemented
"at no cost" in a simple and efficient way by relying on external infrastructures. As a demonstrator we showcase how IOTC size class datasets management can be improved to better feed external initiatives like the Global Tuna Atlas datasets update and related Shiny apps. We explain how this approach can be used beyond fisheries data management and visualization to foster the publication and reproducibility of additional research work like stock assessment models runs outputs.
