  abstract = {1. {S}eabirds and pinnipeds are vulnerable to reductions in prey availability, especially during the breeding season when spatial constraints limit their adaptive capacity. {T}here are growing concerns about the effects of fisheries on prey availability in regions where large commercial fisheries target forage fish. 2. {F}or breeding seabirds and pinnipeds, prey availability depends on a combination of abundance, accessibility, patchiness and distance from the colony. {A}n understanding of the aspects of prey availability that determine foraging success is essential for the design of effective management responses. 3. {W}e used a mechanistic individual-based foraging model based on observed data for two sea-bird species, the {P}eruvian {B}ooby {S}ula variegata and {G}uanay {C}ormorant {P}halacrocorax bougainvilliorum, to simulate the foraging patterns of seabirds feeding on schooling fish. {W}e ran the model over simulated prey fields representing eight possible combinations of high or low prey abundance, shallow or deep prey, and broadly distributed or spatially concentrated prey. 4. {T}he results highlight the importance of the accessibility of prey. {D}epth distribution was the primary factor determining modelled foraging success for both species, followed by abundance, and then spatial configuration. 5. {S}ynthesis and applications. {T}he individual-based foraging model provides a spatially explicit framework for assessing the effects of fisheries on the foraging success of seabirds and other central place foragers, and for evaluating the potential effectiveness of marine-protected areas and other fisheries management strategies for safeguarding central place foragers in dynamic ecosystems. {O}ur analysis indicates that broad-scale fisheries management strategies that maintain forage fish above critical biomass levels are essential, but may need to be supplemented by targeted actions, such as time-area closures, when environmental conditions lead to low prey abundance or reduce prey accessibility for seabirds or pinnipeds of conservation concern. {T}he individual-based foraging model is adaptable and could be reconfigured for application to other species and systems.},
