Broodstock is the key for any successful fish hatchery. Maintaining broodstock at good health and optimum nutrition is vital for high-quality eggs and larvae.

Hormone-induced spawning is used in hatcheries where an environment significantly differs from a natural state, such as when inducing spawning out-of-season. Non-acute stress of hatchery environments may result in lower fecundity and larvae quality, higher deformities and lower stress tolerance.

NutraBrood Enhance is a natural combination of herbal extracts that are specifically designed to reduce stress and regulate the hormonal cycle. NutraBrood Enhance formulation includes adaptogenic, hepatoprotective, antioxidant and immunomodulator herbal extracts.
