When cultural sea water is diluted, prawn must be accommodated their body fluid to differentsalinity of the water by being regulated by the osmotic pressure.Concentration of free amino acids in body fluid of prawn Penaeus japonicus is decreased toadapt itself to the environment according as salinity of cultural sea water is gradually decreased.This phenomenon is explained by the function of osmo-regulation.The prawn changes composition of free amino acids in the body fluid with salinity of thecultural sea water. Main amino acids, which change their concentration and act as osmo-regulation factor, are glycine, proline, arginine and alanine.When the cultural sea water is diluted drastically, the prawn is obliged to be confuged thefree amino acid composition in its body fluid for a few days. |
