Abstract

1. Acclimation of M. rosenberqii by gradual transfer from dilute to more concentrated media caused a significant decrease in the hemolymph protein content. 2. This phenomenon is related with a concomittant increase in muscle ninhydrin-positive substances (NPS) and free amino acids (FAA). The hemolymph NPS is, however, independent of salinity. 3. Glutamic acid, proline, glycine, alanine and arginine constitute 70-80% of the total muscle free amino acids, and their concentrations were elevated by as much as 300% during acclimation to seawater. 4. The results indicate the involvement of FAA in intracellular osmotic adjustments to hyper osmotic stress.
