  abstract = {{T}he {E}astern {C}orsican {C}oast ({ECC}) is distinguished by its shallow sandy shelf, extensive {P}osidonia seagrass meadows, and the relatively limited exploitation of fish in this region. {T}o understand {ECC} trophic functioning and the effects of fishing in this region of the {M}editerranean {S}ea, we applied the {E}copath and {E}co{T}roph ap-proaches. {O}ur model encompassed 5 groups of primary producers and detritus, 14 invertebrate groups, two groups of {C}hondrichthyes, 16 teleost groups, one seabird group, and one group of cetaceans. {T}he {ECC} ecosystem was structured into five trophic levels, regulated top-down by {S}phyraenidae, {E}pinephelus marginatus, and {D}entex dentex. {T}he ecosystem displayed a high degree of benthic-pelagic coupling, confirmed by keystone groups/ species located at intermediate trophic levels (planktivorous teleosts, benthic cephalopods, shrimps, zooplankton). {T}he {ECC} demonstrated the lowest exploitation rate ({F}/{Z}) of all exploited {M}editerranean ecosys-tems, with trawling representing 55% of catches, followed by the lobster net (27%) and fish net (18%) fisheries. {C}atches often included untargeted groups-often discarded dead-in particular sharks and rays, and several protected species. {M}oreover, {P}alinurus elephas, {S}corpaena scrofa, and {D}entex dentex had elevated {F}/{Z} values, highlighting their vulnerabilities to fishing. {A}lthough the fishing simulations suggested that the {ECC} could support a greater exploitation, they also revealed that these fisheries have a marked impact on upper trophic levels. {O}ur study draws attention to the critical habitat the {ECC} provides for {C}hondrichthyes, evidenced by the significant biomass for these taxa and the low fishing pressure relative to other exploited {M}editerranean systems. {T}his first modelling of the {ECC} is an initial step towards modelling all {C}orsican marine ecosystems to serve as a guide for preserving these ecosystems through appropriate management measures.},
