  abstract = {{W}e investigate reference points for ecosystem indicators in support of an {E}cosystem {A}pproach to {F}ishery. {I}n particular, we assess indicator capacity to detect when the {M}ultispecies {M}aximum {S}ustainable {Y}ield ({MMSY}) is reached, under a wide range of multispecies fishing strategies. {T}he analysis was carried out using a simulation approach based on the ecosystem model {OSMOSE} in the southern {B}enguela. {W}e show that the 13 ecosystem indicators have reference points at {MMSY} that are highly variable across fishing strategies. {T}he state of the ecosystem at {MMSY} is so variable across fishing strategies that it is not possible to set reference points without considering the fishing strategy. {H}owever, strategy-specific reference points were found to constitute robust proxies for {MMSY} in more than 90% of the simulated fishing strategies. {F}or instance, under the current fishing strategy in the southern {B}enguela, robust reference points at {MMSY} could be identified for the following indicators: mean length of fish, mean lifespan, biomass over catch ratio, trophic level of the surveys, mean trophic index, proportion of predatory fish, intrinsic vulnerability index, and mean maximum length.},
