Presence of gonadotropin‐releasing hormone immunoreactivity in dogfish and skate brains
Abstract Gonadotropin‐releasing hormone (GnRH) immunoreactivity was studied in two species of elasmobranchs, spiny dogfish ( Squalus acanthias ) and black skate ( Bathyraja kincaidii ). Immunoreactive material in brain sections was identified using the avidin‐biotin technique with the horseradish pe...
