  abstract = {{G}iven the ecological importance and high socio-economic value of the fishery of the {G}ulf of {G}abes, an end-to-end model was applied to its continental shelf ecosystem to characterize the structure of the food web in the 2000s. {T}his approach consisted in forcing a high trophic level model ({OSMOSE}) with an existing biogeochemical model ({E}co3{M}-{MED}) representing the seasonal dynamics of the low trophic levels. {T}he two models were linked through trophic interactions to represent the ecosystem dynamics from primary producers to top predators. {I}n this study, we developed the multispecies, individual-based model {OSMOSE} in the {G}ulf of {G}abes ({OSMOSE}-{G}o{G}). {T}his model aims to capture the main processes that influence species life cycle and simulate the functioning of the ecosystem according to opportunistic predation process based on size selection and spatio-temporal co-occurrence between a predator and its prey. {T}he spatial distribution of the eleven modelled species was derived from a {M}ulti-{S}cale {S}pecies {D}istribution {M}odelling approach. {W}e calibrated {OSMOSE}-{G}o{G} model with available data of biomass and fishing yield, using an optimization method based on evolutionary algorithms which is suitable for complex and stochastic models. {F}inally, {OSMOSE}-{G}o{G} was validated against independent data sets at different hierarchical levels: the individual (diet composition), population (mean size of commercial catch) and community levels (mean trophic level) following the {P}attern-{O}riented {M}odelling approach. {T}he model outputs were overall consistent with the diet compositions and mean trophic levels derived from the {ECOPATH} model of the {G}ulf of {G}abes ({ECOPATH}-{G}o{G}) and the observations of mean size of catches. {T}he {OSMOSE}-{G}o{G} can be considered as a baseline model to investigate ecosystem responses to environmental changes and fishing management measures in the {G}ulf of {G}abes.},
