Secondary productivity measured by harvestable species (such as shrimp and fish) is evaluated in terms of man-related and controllable factors, such as quantity and quality of inlet freshwater and pollutants. This simulation model used information from an existing physical parameters model as well as pertinent biological measurements obtained by conventional sampling techniques. Predicted results from the model compared favorably with those from comparable investigationsASW,USA,Texas,Galveston BaybiologicalBrackishwater pollutionEcosystemsEnergy flowestuariesfishGalveston BayMan-induced effectsmathematical modelsmeasurementO 8050 CONFERENCESPollutantsQ1 01482 Ecosystems and energeticsQ1 01502 Methods and instrumentsQ1 01521 Mechanical and natural changesQ2 02162 Methods and instrumentsQ2 02170 Nearshore dynamicsQ2 02442 Methods and instrumentsRiver dischargeSamplingSecondary ProductivitysimulationTexasUSAwaterWater qualityCONF
