| I like longfins as aquarium fish. And for years I had a 600 gallon aquarium in the kitchen wall that was stocked soley with solid colored longfins. I traded them out when they got to be over 12 inches. The black ones, yellow ones and silver ones looked very graceful when they were young.
The concerns I have stocking longfins will normal koi are many however. If you wish to develop your eye, I think a love of longfins holds you back.
I also think that a pond of mixed 'species' like longfins and nishikigoi is very distracting and the harmony of the pond is somehow upset as a living picture. It may be the way the longfins have to swim ( movement) as much as the look of them?
Of biggest concern , more for the hobby than the individual pond, is the cross breeding issue. Koi, specifically Nishikigoi has been a journey of separating out traits from common carp and mutations. It has been a long hard road and now we seem to be willing to contaminate that gene pool?
Certainly breeder take great care and study of potential brood stock. And the idea that they would accidently select a phenotype parent with genetic links to longfins is frightening. In effect, a phenotype for nishikigoi selected from longfins is a 'genetic poison' to the nishikigoi population. We have seen this problem in many breeding programs of other animals. In dogs, Cockerpoodles are popular pets but they really represent a regression in each breed. Dogs have papers and are somewhat protected at the show and breeding level as only papered dogs can compete and are used in breeding. But koi are not protected this way. So long fins will pop up more and more I suspect.
In short I'd prefer longfins be looked at as a separate breed like Shubunkin, wakins and comets are. Honestly I think they should be judged as those fish are also. But I digress. JR |
