title: Plasma calcium and calcitonin in the marine teleost, Gadus morhua.
abstract: Total, free and ionic plasma levels of calcium as well as total plasma magnesium and inorganic phosphate levels were studied in the Atlantic cod, Gadus morhua, in relation to salmon calcitonin injections. Plasma ion levels and endogenous levels of calcitonin were studied during environmentally induced hypercalcemia. It is concluded that no apparent relationship between calcitonin and calcium levels was found, and it is implied that calcitonin in fish may have a physiological function not related to blood calcium regulation.
