Not all GS populations have the disease. Find the right hatchery and ask questions. Another method is to buy the 250,000-shiner fry option and overwhelm the population issue with numbers.
Yeah that would not be a bad option, I did the Anderson minnow fry thing when I first built the pond and had great success with them.
Although I did get more from the fish supplier that stocked my pond later, and he assured me that a couple dozen young GSH that I stocked later will hatch out as many fry as the two bags I bought from Anderson, which shoulda been approx 500k.
