Calcitonin, a major gill hormone.
Isolated salmon gills, under simulated in vivo conditions, transported calcium ion into the ambient seawater when perfused with Ringer's solution containing salmon calcitonin. Similar enhancement of phosphate efflux was observed. Calcitonin caused simultaneous decreases in perfusate flow rates. The effects act synergistically to diminish net plasma calcium concentrations.
