Ecophysiological responses of Litopenaeus vannamei were evaluated as functions of environmental salinity and animal size. Growth rate, routine metabolic rate, limiting oxygen concentration, and marginal metabolic scope were determined for L vannamei acclimated to, and tested at, salinities of 2, 10, and 28 ppt, all at 28 degrees C. Routine metabolic rate (RMR), estimated as oxygen-consumption rate per unit body weight for fasted, routinely-active shrimp, was independent of salinity but decreased with increasing shrimp weight. Limiting oxygen concentration for routine metabolism (LOCr) decreased with increased shrimp weight for the 10 and 28 ppt treatments, but not for the 2 ppt treatment. Marginal metabolic scope (MMS = RMR/LOCr) also decreased with increasing shrimp weight and was independent of salinity. Growth rate was significantly less at 2 ppt than at either 10 or 28 ppt, which gave similar growth rates. (C) 2009 Elsevier B.V. All rights reserved.
