The osmoregulation of P. chinensis at 308C is as efficient as P. Íannamei. The slope
obtained from the relationship between hemolymph osmolality and medium osmolality
for P. chinensis suggests that shrimps originally maintained in high temperature 308C.
regulate osmotic concentration much better than those at 12, 18, and 248C. This fact also
indicates that P. chinensis juveniles originally maintained at 128C can tolerate more
fluctuations in hemolymph osmolality than those at 18, 24 and 308C.
