This Report summarizes the presentations, discussions and recommendations of the 2010 session of the ICES Study Group on International Ex-post evaluation on Eels which took place in Vincennes, France, hosted by the Onema, from 10 to 12 May 2010. This study group was chaired by Laurent Beaulaton (France) and involved 15 people from 10 countries.This study group is intended to design, test, analyse and report on a method of scien-tific ex-post evaluation of applied management measure at the stock-wide level. This report is the first step towards that objective and mainly focuses on designing the appropriate framework and the methods for eel ex-post evaluation and reviewing available data.A pragmatic framework to ex-post evaluate at the stock-wide level eel management measures has been designed including an overview of potential ex-post evaluation tests, an adaptation to the eel case of the classical ICES precautionary diagram and a framework to compile lower scale stock indicators into stock-wide stock indicators. Available methods to assess the required stock indicators and the available data have been reviewed.Future work will be dedicated to testing the feasibility, sensitivity and robustness of this framework so that the study group will be able to make recommendations on the best ex-post evaluation method for 2012 and data collection and development needed after 2012.
