The population model includes the effects of environmental conditions, predators and (Perkinsus marinus), on oyster populations. The hydrodynamic model includes the effects of wind stress, river runoff, tides and oceanic exchange on the circulation of the Bay. Simulations obtained with the coupled models provide distributions of the total oyster population, market-sized individuals and disease prevalence and intensity that arise in response to differing freshwater inputs. Simulations for high, mean and low freshwater inflows will be presented and discussed in terms of the effects on oyster abundance and productionAbiotic factorsabundanceASW,USA,Texas,Galveston Baybay dynamicsDistributionEcologyenvironmental conditionsGalveston BayInflowMarine molluscsmodellingmodelsO 1070 Ecology/Community StudiesOstrea edulisOyster culturePerkinsus marinuspopulation dynamicsPopulationsQ1 01442 Population dynamicsQ1 01583 Shellfish cultureQ3 01583 Shellfish cultureRunoffSalinitySalinity effectssimulationStressTexasTidesUSAWindCONF
