The effects of sudden salinity changes and rates of reduction in dissolved oxygen content on the lethal dissolved oxygen levels for brown shrimp (Penaeus aztecus) juveniles (51 mm mean length) and subadults (91 mm mean length) were determined by direct transfer from an acclimation salinity of 10 ppt to test salinities of 2.5, 5, 10, and 36 ppt at rates of reduction in … and 3 mysis stages before metamorphosing into postlarvae (Cook and Murphy 1969, 1971). the Bay of Campeche, TX is one area where this species is highly abundant.
