Production of commercial Crustacea in the Aransas River was found to be severely retarded by abnormal salinity and water quality conditions attributed to oilfield brine from Chiltipin Creek. Tributaries of St. Charles Bay had water of very high quality and were normally very productive. The entire St. Charles Bay system appeared to be prime habitat for adult and juvenile food and game species. Heavy rainfall alleviated poor conditions in Chiltipin Creek, the Aransas River and the Mission River, but this relief was short-lived.en-USblue crab populationshrimp populationoilfield brineMission RiverChiltipin CreekSt. Charles Bay, TexasCopano Bay, TexasAransas BayTechnical Report
