(physiology)
Any physiological mechanism for the maintenance of an optimal and constant level of osmotic activity of the fluid in and around the cells.

The differences between the commonly studied low salinity condition and the oscillating salinity condition, more closely resembling the natural fluctuations of an intertidal environment, frame the widely studied osmoregulatory mechanism in a more natural setting.
Apart from the stress caused due to environmental variations, mortality at lower salinities is also possible due to the imbalance in osmoregulatory mechanism (32).
Like the shape transformation reported here, this osmoregulatory mechanism is activated by [Ca.sup.++] and inhibited by ATP depletion (Amende and Pierce, 1980b; Pierce and Maugel, 1985; Pierce et al., 1989).
Horner reported prolactin to have a role in MD by its effect on osmoregulatory mechanisms.6 Together with growth hormone, prolactin is now considered a major stress-induced hormone.
Changes in branchial and intestinal osmoregulatory mechanisms and growth hormone levels during smolting in hatchery-reared and wild brown trout.
Also, because osmoregulatory mechanisms (i.e., ability to regulate salinity) are undeveloped in leptocephali, they probably spawn offshore because leptocephali aren't able to regulate the dramatic environmental changes found in typical estuarine and inshore waters.
Osmoregulatory mechanisms of the mesohalophilic bacterium Bab Pp.
This study provide us to understand the osmoregulatory mechanisms of trouts during seawater acclimation and may contribute knowledge to solve problems about adaptation.
A driving force for most osmoregulatory mechanisms is NKA and an imbalance in the concentration of many ions is likely to affect the activity of NKA.
