Many nations have long-term scientific research surveys, originally driven by conventional approaches in fisheries assessment and management. The aim of this study is to address the practical concerns linked to current objectives of monitoring simple EAF indicators, using data from surveys that were not historically designed for the purpose. Based on the results of an expert survey designed to collect expert knowledge on research surveys from scientists working on different ecosystems worldwide, a list of challenges faced during indicator estimation is highlighted, along with associated concerns and constraints. The work provides additional information useful in the interpretation of the results obtained on the state and trends of ecosystems using EAF indicators by the IndiSeas WG. Further, the related discussion provides potential pathways that could be useful for future research and development aiming to improve the ecosystem indicator approach in the operational context of EAF. The question of the utility for EAF of using historical dataseries of scientific trawl series is also discussed. Such long-term series are concluded to be useful, that they are even inescapable (since the past cannot be resamplied), and that EAF therefore brings a supplementary reason for continuing such monitoring and to incorporate new insights in how research surveys may be conducted. specialized EAF ecological indicators ecosystem effect of fishing historical data trawling surveys 040 67 4 796-806 2010 1054-3139 https://www.documentation.ird.fr/hor/fdi:010049511 10.1093/icesjms/fsp285 1054-3139 [F B010049511] https://www.documentation.ird.fr/hor/fdi:010049511 https://www.documentation.ird.fr/intranet/publi/2010/05/010049511.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2010-06-02 2017-08-23 fdi:010049511 fre
