Extended Koi Quarantine: When and Why to Hold Longer
By KoiQuanta Editorial Team|
KHV quarantine in warm water may need to extend to 12 weeks to confirm disease freedom. That's three times the standard quarantine period for the same pathogen, and the reason is temperature biology: KHV is only detectable through clinical signs when the water is in the active temperature window (16-25°C). A fish imported in winter may spend 4-6 weeks in quarantine without ever experiencing the temperature conditions needed for latent KHV to manifest.
KoiQuanta automatically suggests extended holds for high-risk source or disease history scenarios. No competitor triggers hold extensions based on risk factors in this way.
