Abstract
Three species of fish that are phylogenetically older than other members of the bony fish lineage were selected to determine if gonadotropin-releasing hormone (GnRH) is present in their brains. Brain extracts were prepared from each species and found to contain immunoreactive (ir) GnRH. To further characterize the molecular forms of GnRH in each species, the extracts were injected into a high pressure liquid chromatograph (HPLC). The elution time of each GnRH-like form was compared to those of the synthetic forms of the five known GnRHs
