Invertebrates play important and diverse functional roles in marine ecosystems, yet the ecosystem effects of their exploitation are poorly understood. Using 12 ecosystem models distributed worldwide, we analysed the trade-offs of various invertebrate fisheries and their ecosystem effects as well as ecological indicators. Although less recognized for their contributions to marine food webs, our results show that the magnitude of trophic impacts of invertebrates on other species of commercial and conservation interest is comparable with those of forage fish. Generally, cephalopods showed the strongest ecosystem effects and were characterized by a strong top-down predatory role. Lobster, and to a lesser extent, crabs, shrimp and prawns, also showed strong ecosystem effects, but at lower trophic levels. Benthic invertebrates, including epifauna and infauna, also showed considerable ecosystem effects, but with strong bottom-up characteristics. In contrast, urchins, bivalves, and gastropods showed generally lower ecosystem effects in our simulations. Invertebrates also strongly contributed to benthic-pelagic coupling, with exploitation of benthic invertebrates impacting pelagic fishes and vice versa. Finally, on average, invertebrates produced maximum sustainable yield at lower levels of depletion (similar to 45%) than forage fish (similar to 65%), highlighting the need for management targets that avoid negative consequences for target species and marine ecosystems as a whole. specialized Ecological indicators Ecopath with Ecosim ecosystem-based fisheries management functional roles invertebrate exploitation trophic impacts 040 036 020 18 1 40-53 2017 1467-2960 https://www.documentation.ird.fr/hor/fdi:010069325 10.1111/faf.12165 1467-2960 [F B010069325] https://www.documentation.ird.fr/hor/fdi:010069325 https://www.documentation.ird.fr/intranet/publi/2017/04/010069325.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2017-05-09 2017-08-23 fdi:010069325 fre
