  abstract = {{D}uring the last decade, oyster aquaculture has rebounded in {V}irginia and has been associated with an increase in subaqueous leased area. {P}roduction levels remain historically low, however, and many leases are thought to be underutilized. {T}his study uses a novel approach leveraging high-resolution environmental data to evaluate lease utilization and identify constraints on aquaculture development. {S}tochastic {F}rontier {A}nalysis ({SFA}) and {D}ata {E}nvelopment {A}nalysis ({DEA}) were used to define environmentally-determined production frontiers, i.e. production possibilities based on empirical observations of aquaculture production, available space, and environmental conditions. {B}oth methods estimated {L}ease {C}apacity {U}tilization ({LCU}, from 0 to 1) for leases producing oysters with intensive culture methods from 2007 to 2016. {M}odels revealed significant heterogeneity in lease utilization and mean {LCU} scores of 0.25 ({DEA}) and 0.27 ({SFA}), which suggests many leases could scale up production or reduce the size of their lease to more efficiently utilize ambient environmental conditions (i.e., achieve scores closer to 1). {C}apacity underutilization arising from characteristics of the leaseholder and surrounding spatial environment were quantified and indicated efficiency gains for horizontally integrated leaseholders, though also suggested leases in more populated areas were less efficiently used, possibly due to increased use conflicts. {T}hese results highlight potential externalities and tradeoffs associated with aquaculture development and can inform the design of more efficient aquaculture leasing systems.},
