Simon,
There is no definitive size at which carp mature. Notwithstanding the new fast growing F1 and F2 strains, the norm for the Uk will be that carp become mature at around 3 to 4 years. However, the principal factor determining this is water temperature and, to a lesser degree, light. In warmer climates smaller sized carp can become mature from around 1 year.

Furthermore, once they are mature they require water temperature to exceed 18c for a few days to trigger the hormones. Successful breeding therefore also requires a few other considerations, such as location and size of the breed pool and water flow - try to avoid it being spring fed as it lowers the temperature. Many breeders enhance their success rates by using heated tanks at around 22 to 24C and giving the females a hormone injection before hand stripping them off their eggs.

If you really are thinking of going down this route speak to Sparsholt. They have some great books on the subject and £20 or so is nowt to pay for advice that could save you thousands.

Cheers,
Stu

PS I look forward to receiving my free season ticket!!!
