Two types of gonadotropin extracts have been used to induce ovulation in fish: Human Chorionic Gonadotropin (HCG) and fish pituitary extract.
* Pituitary extracts are made by removing the pituitary from a fish and extracting the hormones, which may then be injected into another fish.
** Carp, catfish, salmon and other fish have been used.
* HCG offers three major advantages over the pituitary extract:
** Less expensive
** More stable and thus has a longer shelf life.
** Comes in a purified form
