The value of the "idea" for a certification program is there, but I don't know how far into the hobby it will reach.
Folks like us deal with people who have already been found to have well established track records, excellent biosecurity, and top notch protocols in place. Even so, we still self-quarantine new acquisitions as an added step of self preservation. The high end dealers/breeders already know their stuff and put it into practice every day, so an "AKCA Certification" would add no value to their business or their customers level of confidence. It would only tell their new customers what the rest of us already know.
On the other hand, there are plenty of backyard breeder/dealers who are in the quick buck speckldiegoi market who have absolutely no concept of "best practices" and neither do their customers. Annual replacement of die offs is their major market share, so going to a lot of trouble to prevent disease is not even on their radar. Everyone reading this probably has better QT setups than some of the Junk Koi marketers out there, and we all know it.
Where I can see the value of this coming into play is with newer entrants into the marketplace.
"So you want to become a Koi Dealer"... Well here's what it takes to serve the hobby well... An established set of minimum standards of health assurance for your business and your customers. Compliance would at least act as a solid foundation for best business practices for those who really are serious. A CONSUMER driven set of standards plays to the old adage of "The Customer is ALWAYS Right", and those who want to do business with better customers would find it in their own self interest to join the "Kichi Crowd".
Obviously, the low rent dealers/breeders would still be out there doing what they already do, but their customers have probably never heard of AKCA, ZNA, or even know about nasty things like KHV, etc... The bottom feeders of the Koi market are the Koi worlds equivalent of street vendors hawking knock off Gucci bags and fake Rolex watches, and sadly enough most of their customers are dumb enough to think they're getting a bargain on the real thing...
