The Identification File: Photos and Markings, Fish by Fish
Insurance stands or falls on proving that the koi in the pond is the koi on the paperwork, and koi are identified from above. Keep a clear top-down photograph of every fish, taken in a shallow bowl of pond water where it lies calm and fully visible, plus a side shot for body shape. Beneath each photo, record the variety in the trade's own terms — kohaku, sanke, ogon and so on — and a written description of the pattern as if the photo were lost: where the red sits, the mark that makes this fish unmistakable. Update the portrait as the fish grows and the pattern shifts, keeping the older shots, because the sequence itself is identification.
Ages, Sizes and Where Each Fish Came From
For every koi, keep the source: the dealer or breeder's name, where they are, and the receipt or certificate that came with the fish, filed or photographed with the record. Note the age as sold — breeders often sell young fish by their season — or mark it plainly as estimated, with the evidence for the estimate. Add a size line you update as the fish grows, measured snout to tail in the bowl during routine health checks rather than guessed through the pond surface. An insurer presented with source, age and a growth sequence is looking at an asset file, not a pet story, and that is precisely the point.
Keeping the Value Side Current Without Guesswork
A koi's value changes as it grows — often dramatically, in both directions — so the record needs a value line that is maintained, not a single figure frozen at purchase. Keep the purchase paperwork as the anchor, then add periodic support: a dealer's updated appraisal when you have one, records of show results if the fish is shown, and notes of comparable sales you genuinely know of. Store the basis beside every figure so a future claim can show its working, not just a number. What matters to an insurer is that the value was documented before anything went wrong, by evidence that already existed.
Health and Pond Events That Belong in the Same File
Claims get harder when the fish's history is scattered, so keep the significant events with the identity file: treatments given and why, quarantine records for pondmates added later, any losses in the pond and their likely cause, and the pond work that changes risk — a liner replaced, a filter upgraded, a heron net fitted. Note the pond's own details too: its volume, its filtration, and the winter arrangements. If a claim ever follows a theft, a pollution incident or a predator attack, this file is what turns your account of a valuable collection into a documented one. That single-file discipline is exactly what KinsLe's Pet Passport provides for pond keepers: each koi's photographs, sources, ages and valuations kept together in one portable packet, ready for an insurer, a vet or a buyer whenever the records are called for.
