Monoamine fluorescence was studied in the caudal neurosecretory system of eighty‐four adult carp, Cyprinus carpio, of either sex. Some neurosecretory cells were surrounded with monoaminergic fluorescent varicosities, while others were not. The varicosities werc: also found adjacent to nerve terminals or capillaries in the urophysis. Noradrenaline, but not adrenaline or dopamine, was detected memically in the urophysis and the spinal cord. These results suggest that noradrenergic neurons seem to regulate both the synthesis and the release of neurosecretory material in the carp caudal neurosecretory system.
