wow..i had a dream about this last night..except Li was the one cloning the fish...LOL
i had a midas that died and i sent him a scale for DNA, and the cloned fish fell out of the ceiling into the tank..then i started asking him for different clones(lungfish, dats and an armatus LOL)
There will most likely never be a reason to clone fish on a large scale.
Lets face it, everything is done for money. There is not a good enough economic reason to clone fish on a large scale. The biggest $$ in fish is obviously for food purposes. It is easy enough to harvest wild fish and to farm other fish that there would be no use for cloneing.
Cloning no...but I CAN see genetic manipulation sneeking into the hobby down the line...
If you don't think so then concider how many man made Hybrids are already for sale...they sell well I might add because they are new and differant.
So a lab created pair of fish with attributes people would like and then natural breeding from then on? I'd be surprised if someones not working on this already....
