  abstract = {{I}n the context of ecosystem-based fisheries management, which should consider changing and uncertain environmental conditions, the development of ecosystem-based biological reference points ({EBRP}s) to account for important multi-species ({MS}) interactions, fishery operations, and climate change, is of paramount importance for sustainable fisheries management. {H}owever, {EBRP}s under varying plankton productivity states and fisheries management strategies are seldom developed, and the ecosystem effects of these changes are still largely unknown. {I}n this study, ecosystem-based {F}-{MSY} (fishing mortality rate at {MSY}) values were estimated within an end-to-end ecosystem model ({OSMOSE}) for three focused fish species ({P}acific {H}erring, {C}lupea pallasii; {P}acific {C}od, {G}adus macrocephalus; {L}ingcod, {O}phiodon elongatus) under three plankton productivity states of differing plankton biomass at high, current, and low levels. {I}n addition, ecosystem effects were compared across different plankton productivity and fisheries management strategies with the latter consisting of two fishery scenarios (i.e. single-species-focused ({SS}) and {MS}-focused), various fishing mortality rates, and two harvest policies (with and without harvest control rules, {HCR}s). {M}ain findings of this study include: (i) plankton productivity change affected the values of ecosystem-based {F}-{MSY}, which increased as plankton productivity states changed from low to high plankton biomass; (ii) ecosystem-based {F}-{MSY} for {P}acific {H}erring and {P}acific {C}od stocks increased when fishery scenarios shifted from {SS}-focused to {MS}-focused; (iii) fisheries management incorporating {HCR} yielded more stable system catch and system biomass; and (iv) high plankton biomass combined with fisheries management using {HCR} could maintain stable ecosystem production and sustainable fisheries. {B}ased on our findings, we highlight possible adaptive fisheries management strategies in the face of future climate and ocean changes. {O}verall, {EBRP}s complement {SS} stock assessments by incorporating key ecological processes and ecosystem properties, thus providing supporting evidence for better incorporation of ecosystem considerations into scientific advice for sustainable fisheries management.},
