What is Ovaprim?
Ovaprim is a two-part drug consisting of 1) a shorter, synthetic version of GnRH and 2) domperidone. Ovaprim is marketed ready to inject in a liquid form.
In the ornamental fish industry, Ovaprim is used as a spawning aid to induce ovulation (release of mature oocytes/eggs) and spermiation (release of milt/sperm) in mature, properly conditioned brood-fish. Ovaprim is especially useful for species for which natural spawning in captivity is difficult to induce.

NOTE: Use of Ovaprim does not guarantee successful fertilization, development, and hatch of fry. Overall good husbandry and hatchery management, including good genetics, proper nutrition, environment (including water quality), substrates, social structure, and other factors will affect egg and milt quality, egg hatch, and fry survival.
