Your customers depend on you for healthy, dependable fish. And you can depend on us.

We know that stocking strong, healthy, vibrant Koi, Butterfly Koi and Goldfish is crucial to your business. Offer anything less, and you risk losing customers. That’s why we go to great lengths to offer the healthiest fish possible.

Bio Security

Blue Ridge Koi & Goldfish operates under a strict bio-security plan. This plan ensures that our production farms avoid possible contamination from outside threats.

Our production farms have operated as closed facilities since bringing in new brood stock in 2003. No new fish have been brought onto our production farms. We have not added any new brood stock, and any fish that leave our facilities are never allowed back.

All water entering our ponds and holding facilities passes through industrial-strength sand filters and UV sterilizers

Passing through the sand filters first, water is filtered down to 20 microns. From there, water is sent onward to the UV sterilizers, which kill any viruses present in the water. Sensors monitor the UV dosage constantly, and the water flow is shut down automatically if the dosage ever falls below the known kill rate for SVC (spring viremia of carp) and KHV (koi herpes virus).

After passing through treatment, the water is sent on to our ponds and holding facilities. Upon completion of the treatment, our water is parasite free and literally clean enough to drink.

All Imported Koi are sourced from Aquamade, a collection of biosecure indoor koi facilities in Israel. Learn more about Biosecure Imported Koi.

Pond Maintenance

We operate over 200 mud ponds, with each monitored closely to ensure optimal fish health.

Parameters such as dissolved oxygen levels, ammonia, nitrite, pH and salinity are closely monitored and adjusted in order to provide the best possible environment for Koi and Goldfish to thrive.

Additionally, samples from each pond are examined microscopically for parasites and other health issues. Any affected ponds are treated accordingly.

Koi and Goldfish can have health issues that are not apparent while they are in the pond, but become apparent after they are harvested and brought into our holding facilities. For this reason, everything we sell is quarantined for a minimum of 14 days before being sold.

All Koi and Goldfish are kept in greenhouses at temperatures of 70 to 75 degrees, where health issues are most likely to become apparent. All fish are monitored closely. A sample from each pond is examined microscopically to search for the presence of parasites. If health issues are found in any batches of fish, sales of all fish from that pond are suspended until we can verify that the issue has been resolved.
