Proline accumulation, apart from being important in osmoregulation and acting as a nitrogen reserve, may reduce stress in itself, acting as a substrate for respiration and generating energy that could be inverted for plant recovery from stress (Tarakcioglu and Inal, 2002).
The integument participates in several important functions, such as exchange of gas, ions, molecules, secretion of mucous substances, osmoregulation, immunity, and forms a physical barrier against different aggressive agents (WAHLI et al.

It exerts a diverse array of biological effects, including cardiovascular regulation, antioxidation, modulation of ion transport, membrane stabilization, osmoregulation, modulation of neurotransmission, bile acid conjugation, hypolipidemia, antiplatelet activity and modulation of fetal development.
However, osmoregulation in this species has not been examined in great detail.
In decapods, the ability for osmoregulation at very low salinities generally develops only by late larval or early juvenile stages (33).
