Resumen
Osmoregulation in Litopenaeus vannamei was studied in a factorial experiment at four temperatures (20, 24, 28 and 32 °C) and six salinities (10, 16, 22, 28, 34 and 40 ). The isosmotic related points for 20, 24, 28, and 32 °C were 754, 711, 822, and 763 mmol/kg, respectively. This species hyperregulates between at salinities of 10 and 20 and hyporegulates between 20 and 40 . The isosmotic point in L. vannamei exposed to constant salinities changed in relation to temperature from 717 to 823 mmol/kg. For these experimental conditions, the T-S combination of 32 °C and 28 produced the best growth. Rev. Biol. Trop. 54 (3): 745-753. Epub 2006 Sept. 29.
