Statistical models provide a diagnostic on the impact of MPAs on the ecosystem and resources; they are also needed for devising and assessing sampling designs for monitoring programs. Dynamic models enable exploration of the consequences of MPA designs and other management policies. We briefly review how each of these approaches has been implemented up to now in the literature and identify potential indicators of MPA effects that can be obtained from each approach to provide scientific advice for managers. Methodological gaps that impede the assessment of MPA effects and the construction of appropriate indicators are then discussed, and recent developments in this respect are presented. We finally propose ways to reconcile the two approaches based on their complementarity to derive suitable indicators to support decision making. In this respect, we suggest in addition that MPA managers should be associated from the beginning to the design and construction of indicators. specialized 040 65 4 765-779 2008 0706-652X https://www.documentation.ird.fr/hor/fdi:010087021 10.1139/F08-026 0706-652X [F B010087021] https://www.documentation.ird.fr/hor/fdi:010087021 https://www.documentation.ird.fr/intranet/publi/2022-12/010087021.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2008-05-30 2022-12-19 fdi:010087021 fre
