Low concentrations of oxygen determine marine species distribution and abundance 1 along the Peruvian 2 coast with consequences for human activity such as fishing and aquaculture. In order to assess bioener3 getic consequences of oxygen limitation on the Peruvian scallop Argopecten purpuratus, we first devel4 oped a Dynamic Energy Budget (DEB) model of growth and reproduction calibrated on field experimen5 tal datasets. Then, we included oxygen availability as an additional forcing variable using a simple rule 6 based on the ability of the scallop to regulate oxygen consumption. The resulting model was tested using 7 growth/reproduction monitoring and simultaneous high frequency environmental records in Paracas Bay 8 (Peru) at two different depths: suspended in the water column and on the sea bottom. Simulations indicated 9 that scallops growth and reproduction was not food-limited. The negative observed effects of hypoxia on 10 growth and reproduction could be explained by a decrease in both assimilation and reserve mobilization. 11 However, hypoxic conditions in summer were not sufficient to explain the observed losses in somatic tissue 12 weights and the disruption of reproduction. The latter two patterns were better simulated when assuming in13 creased somatic maintenance costs due to the presence of H2S during milky turquoise water discolouration 14 events observed during summer.
