For those who are interested in becoming a certified Koi Health Advisor, check out the Koi Health Advisor Program offered by AKCA. Details are available at the AKCA website. 

The Koi Health Adviser program is a hobbyist to hobbyist support group. It puts more experienced Koi keepers in touch with those learning about the hobby.

The KHA program is not intended to replace the professional veterinarian, but to put a "fellow Koi keeper" out there to help. Is the problem water quality issues or is there a serious health problem? If the pond needs the attention of a Veterinary Professional then the KHA can help the owner get in touch with those vets that deal with ponds or give the open minded local vet a vet contact who does deal with ponds for professional information.
