Salinity of this brine ranged from 82.4 to 91.6 parts per thousand. Mortalities were noted in all tests using brown shrimp (Penaeus aztecus), white shrimp Penaeus setiferus), and juvenile blue crabs (Callinectes sapidus). Brine concentrations of above 40 per cent produced 100 per cent mortalities on all species tested.en-UScrab mortalityshrimp mortalityoilfield brinetoxicityhypersaline conditionsecological surveyTechnical Report
