Ovaprim is a potent ovulating/spermiating agent used to promote and facilitate reproduction of many species of fish. Ovaprim is a stable solution that contains OvaRH and a dopamine inhibitor. Time to ovulation following Ovaprim injection is highly predictable, with high egg fertility and viability. Ovaprim utilizes the fish’s own endocrine system to safely induce maturation and coordinate spawning dates. When used in the normal spawning cycle, Ovaprim can synchronize and coordinate maturation in treated fish by inducing maturation without affecting viability or fecundity.
