This voluntary program, called OCUP for "Observateur Commun Unique et Permanent" (Common Permanent Unique Observer) was conducted with the Institute for Research and Development (IRD), Oceanic Développement (OD) and several coastal countries. It was implemented in both Atlantic and Indian Oceans where the fleet adherent to ORTHONGEL is active. This paper describes the methodology of the OCUP program and presents and discusses its main results, focusing on the Atlantic Ocean. In the Atlantic Ocean, 43 scientific observers from 6 African countries have been trained as OCUP. Together with 39 French observers from IRD and OD, 37 of these African scientific observers have covered more than 300 trips until September 1st, 2017 and the coverage of the French fleet has reached 100% since 2015. Since 2013, the OCUP program allows a better coverage of many fishing information such as bycatch or incidental catch and discards data but also provides the boat-owners information on the implementation of best practices aboard their vessels. Lessons learned from this program allow the authors to suggest a few recommendations. %B ICCAT Standing Committee on Research and Statistics (SCRS) %8 2017/11 %$ 040PECHE02 ; 030OCECAM
