Comparing Ovaprim and Natural Hormone In Catfish Breeding
Synthetic hormone (Ovaprim) and natural hormone (homoplastic hormone-pituitary extract from the Catfish).
Induced spawning of African Catfish
With more research and networking, cheaper and more effective synthetic hormones are now in use, the most popular being Ovaprim used in catfish breeding. Various other derivatives are also available, especially those from Asia such as Suprefact and Motilium from Thailand.
The results showed that Ovaprim performed significantly better.
Comparative cost benefit analysis showed that ovaprim which recorded better results, was also relatively cheaper. Ovaprim worth N3467.00 was used for induced breeding of H. bidorsalis with combined body weight of 13.38 kg while pituitary hormone extracted from N 6350.00 worth of H. bidorsalis can be used for induced breeding of gravid H. bidorsalis with combined body weight of 12.72 kg. Because of its
relatively cheap cost, ease of handling and better survival of hatchlings from Catfish, Ovaprim is highly recommended for hatchery users.
WHY IS OVAPRIM RECOMMENDED?
Effects of hormonal treatment on pre and post spawning body weight: Increase
Effects of hormonal treatment on number of fertilized eggs: Increase
Effects of hormonal treatment on number of dead eggs after fertilization: Reduce
Effects of hormonal treatment on hatchability of eggs: Increase
Effect of hormonal treatment on percentage survival: Increase
