| Part of it is knowing how to pick parents, and getting the right matches for male and female from the same bloodlines. You almost need a miracle to find out how to do that and also be able to get the right fish. The Japanese have made it available to the diligent and hard searcher, but wisely do not simply pass out that info to everyone. You have to dig.
One other reason is americans want to use a lake, not a pond, and have a very uncontrolled environment due to that. I have seen koi breeders with goldfish in their breeding ponds, and they use the saem ponds for breeding as they do for growing. One reason for that is simply water supply due to location. You almost need free water and a huge RO unit. They aslo tend to keep trying to get away with hard water and high ph, and that drastically affects quality. Weather is also a factor, hard to produce volume if you only breed once a year. Many of them have also not got the marketing skills to get the volume you spoke of. |
