Sometimes it's painful to this about genetic dilution and all that for the loss of what is old and unique. It is however the future in motion. We are witnessing evolution in real time! I'd love to come back in 10000yrs and see what became of these hybrids 😊
The crucian carp is a widely distributed European species, its range spanning from England to Russia; it is found as far north as the Arctic Circle in the Scandinavian countries, and as far south as central France and the region of the Black Sea... It has been established that the fish is native to England and not introduced. [Wikipedia]
According to Peter Rolfe's excellent crucian book ('A Crock of Gold'), there is quite a lot of evidence to suggest that the crucian (Carassius carassius) was introduced to Britain in the 17th or 18th Century and there are no records of them before then. The much larger common carp (Cyrprinus carpio) was thought to have been introduced in the 13th or 14th Century.

What about Carassius auratatus gibelio? The prussian carp and the goldfish are closer in phylogeny than crucian carp, but I don't think people would often care as to where they came from since Carassius is very notorious for being so similar to each other and even now, Japanese crucian carp and other related inhabitants simply takes more than the eye to classify differences. I'm in a goldfish council society working as a researcher. I don't have much experience with phylogenetics or placement of a species so I do want to know your expertise on that matter. Seeing as Carassius Carassius Carassius went with Crucian Carp for goldfish before Carassius Carassius auratus then Carassius auratus gibelio/Carassius Carassius gibelio on Prussian Carp startled me
