“…Immunoreactive GnRH was seen as brown granular reaction product in the cytoplasm and processes of certain neurons. Specificities and crossreactivities of primary antisera (salmon-, mammalian-, and chicken II-GnRH) used in this study have been verified with heterologous and homologous forms of GnRHs and with various neuropeptides (Kelsall et al, 1990;Sherwood et al, 1991;Muske and Moore, 1994;Parhar et al, 1996a). Omission or absorption of the primary antisera at the working dilution with 1 µg/ml of salmon-, mammalian-, or chicken II-GnRH blocked all immunoreactivity.…”

“…cGnRH-II is universally distributed in bony fish (1). In addition to cGnRH-II, mGnRH is found in lobe-finned fish (19), the ancient ray-finned bony fish that evolved before the teleosts (20,21), and in teleosts that evolved early such as Pantodon (22) and eels (23). All other teleosts studied to date have salmon GnRH with the exception of catfish, which has cfGnRH (15).…”

“…It is known that the sturgeon brain secretes mammalian-type GnRH (Sherwood et al 1991), but the sites of secretion and interaction of GnRH with pituitary gonadotropes have not been identified. Studies in our laboratory with white sturgeon,Acipenser transmontanus have shown the gonadotropin releasing hormone analog D-Ala 6 -des-Gly' 0 -GnRH ethylamide (GnRHa) to be an effective stimulant for the release of two gonadotropins, termed sturgeon gonadotropin I (stGTH I) and sturgeon gonadotropin II (st GTH II) (Moberg et al 1991a(Moberg et al , 1995.…”
