Time course of changes in total free amino acid concentrations in the hemolymph of propped-open M. dcmissus during low salinity acclimation. Mussels were previously ac- climated to full strength sea water. Points are mean values from six animals. Error bars represent standard error. salinities, the total free amino acid concentration of the hlood was significantly higher in the experimental mussels (4 hours, P < ; 12 hours, P < ). At the 24 hour sampling period the mean free amino acid concentration in the blood of experimental animals was still much higher than the control mean concentration. However, the variation in concentrations within the experimental group was large enough so that no statistical difference could he found between the two groups of mussels. After 60 hours the total free amino acid concentration in blood of the animals in low salinity had declined toward control values and was not significantly different. Following complete acclimation to low salinity, mussels have total blood amino acid concentrations much lower than those of animals acclimated to full strength sea water. The mean total free amino acid concentrations (± standard errors) in blood of animals acclimated for five weeks to full strength and 50% sea water were ± and ± amino acids ml blood, respectively. Free ainlno acid concentrations in tissues during acclimation The total free amino acid pool in ventricles of mussels acclimating to 50% sea water decreased steadily with time (Fig. 5). Mean values of total amino acids.
