Ovatide Fish Hormone

About Ovatide Fish Hormone

Ovatide is a synthetic fish hormone commonly used in aquaculture to induce artificial breeding (spawning) in fish, particularly in species that do not breed easily in captivity. It's widely used across Asia, especially in India, for breeding various freshwater fish species.

What is Ovatide?

Ovatide is a hormonal preparation containing synthetic Gonadotropin Releasing Hormone analogue (GnRH-a), often combined with a dopamine antagonist (like domperidone). This combination effectively stimulates the pituitary gland to release gonadotropins, which trigger ovulation and spermiation.

Uses in Aquaculture

• Induces spawning in male and female broodstock

• Commonly used for carps, catfish, murrels, and some exotic species

• Used in both natural pond breeding and hatchery systems

Composition (may vary slightly by brand)

Dosage (Typical, but varies by species and size)

• Female fish: ~0.5 1.0 ml/kg body weight

• Male fish: ~0.3 0.5 ml/kg body weight

• Usually given in two injections for females (priming and resolving doses)

Always refer to specific species guidelines or consult a fishery biologist for accurate dosage and handling.

Precautions

• Handle broodfish carefully during injection

• Maintain optimal water quality

• Observe fish for spawning behavior

• Overdosing can cause stress or harm

Advantages of Using Ovatide

• Reliable breeding in non-spawning seasons

• High fertilization and hatching rates

• Cost-effective and easy to administer
