Adverse effects of temp to postlarval brown shrimp (Penaeus aztecus) were examined when such shrimp encountered a temp change similar to that encountered at the time of release into culture systems. Temp differential for the tests was a change of 11°F. The original water temp contained acclimated shrimp at 69°F, while the 2nd temp was established at 80°F. Treatments utilized 75 test animals each and consisted of : sudden change brought about by placing the animals directly into the water of higher temp, gradual change to the higher temp over a 10-min period, gradual change over a 2-hr period, and no change by retaining test animals at the lower temp. No significant differences were found between treatments, indicating that postlarval brown shrimp do not experience acute adverse dffects when cooled to shipping temp and then exposed to a 11°F temp change.
