Abstract
Plasma electrolytes (sodium, potassium, and chloride) were studied in the early winter Gasterosteus aculeatus, form trachurus, at intervals after transfer of the fish from seawater to fresh water. A single injection of prolactin, 24 hours before transfer, reduced significantly the rapid fall of plasma sodium and chloride levels which occurred in the solvent-injected or intact controls, but appeared to have no effect on plasma potassium. The significance of these findings is discussed.Keywords
