The paper describes a bioenergetic individual-based model of the growth of Tapesphilippinarum, a bivalve mollusc reared in the lagoons of the Northern Adriatic Sea. The model, which simulates the evolution of the size of an average individual, has been calibrated using different sets of experimental data collected in the lagoons of Venice and Goro, and has been validated against a 3 yr long, independent series of field measurements of the average size of a cohort. The formulations here proposed for describing the dependence of the gain and loss terms on water temperature and food ration have not been employed in relation to this species before, and allow one to apply the model also in eutrophic conditions. Possible applications of the model as a tool for site selection and management implementations are illustrated.

Role and Value of Nitrogen Regulation Provided by Oysters (Crassostrea virginica) in the Mission-Aransas Estuary, Texas, USA

Suspension-feeding activities of oysters impart a potentially significant benefit to estuarine ecosystems via reduction of water column nutrients, plankton and seston biomass, and primary productivity which can have a significant impact on human well-being. This study considered nitrogen regulation by eastern oysters Crassostrea virginica in the Mission-Aransas Estuary, Texas, USA, as a function of denitrification, burial, and physical transport from the system via harvest. Oyster reefs were estimated to remove 502.5 kg N km−2 through denitrification of biodeposits and 251.3 kg N km−2 in burial of biodeposits to sediments. Nitrogen is also physically transported out of the estuary via harvest of oysters. Commercial harvest of oysters in the Mission-Aransas Estuary can remove approximately 21,665 kg N per year via physical transport from the system. We developed a transferable method to value the service of nitrogen regulation by oysters, where the potential cost equivalent value of nitrogen regulation is quantified via cost estimates for a constructed biological nutrient removal (BNR) supplement to a wastewater treatment plant. The potential annual engineered cost equivalent of the service of nitrogen regulation and removal provided by reefs in the Mission-Aransas Estuary is $293,993 yr−1. Monetizing ecosystem services can help increase awareness at the stakeholder level of the importance of oysters beyond commercial fishery values alone.

“…A decline in length is manifested by three possible conditions. First, food supply, either quantity or quality, may have declined; the former occurs because either upstream concentrations changed or increased crowding reduced food availability downstream (Fr echette & Bourget 1985, Powell et al 1995, Wall et al 2011. Second, filtration rate is a function of temperature and for oysters salinity.…”
