GnRH-ir fibers distribute in the various brain region from the olfactory bulb to the cerebellum. They are especially abundant in the hypothalamus, the preoptic area and the ventral telecephalon. The immunopositive reaction in precocious fish is evidently stronger than that in unprecocious fish, and there is only very weak reaction in the gonadal undeveloped fish. The differences are most obvious in the hypothalamus, but not in other areas.
