  abstract = {{L}ow concentrations of oxygen determine marine species distribution and abundance along the {P}eruvian coast with consequences for human activity such as fishing and aquaculture. {I}n order to assess bioenergetic consequences of oxygen limitation on the {P}eruvian scallop {A}rgopecten purpuratus, we first developed a {D}ynamic {E}nergy {B}udget ({DEB}) model of growth and reproduction calibrated on field experimental datasets. {T}hen, we included oxygen availability as an additional forcing variable using a simple rule based on the ability of the scallop to regulate oxygen consumption. {T}he resulting model was tested using growth/reproduction monitoring and simultaneous high frequency environmental records in {P}aracas {B}ay ({P}eru) at two different depths: suspended in the water column and on the sea bottom. {S}imulations indicated that scallops' growth and reproduction was not food-limited. {T}he negative observed effects of hypoxia on growth and reproduction could be explained by a decrease in both assimilation and reserve mobilization. {H}owever, hypoxic conditions in summer were not sufficient to explain the observed losses in somatic tissue weights and the disruption of reproduction. {T}he latter two patterns were better simulated when assuming increased somatic maintenance costs due to the presence of {H}2{S} during milky turquoise water discolouration events observed during summer.},
