In vitro effects of prolactin, cortisol, aldosterone, and cyclic adenosine monophosphate were studied on branchial Na+, K+ - activated ATPase of freshwater adapted killifish, Fundulus heteroclitus. Decreases in ATPase activity were found after treatment with prolactin and aldosterone. Cyclic AMP caused an increase in ATPase activity. The action of cortisol on this enzyme was not clear.A dose - response relationship was found only for cyclic AMP .It is proposed that cyclic AMP may be involved in the adaptation of F. heteroclitus to seawater.
