Abstract

The concentration of circulating 1,25-dihydroxyvitamin D was measured by means of a specific radioreceptor assay in male, nonspawning female, and spawning female trout. Male trout showed serum levels of 1,25(OH)2D which were comparable to those of weanling rats and infant children and higher than levels found in female trout, 1,25-dihycrosyvitamin D levels in nonspawning and spawning female trout were comparable, despite significant higher levels of circulating calcium and phosphate in the spawning trout. The study documents the existence of 1,25-dihydroxyvitamin D in the blood of teleost fish for the first time.
