Blaine,
Not sure about your area, but in my area of Indiana a RELIABLE supplier of triploid grass carp could probably do pretty well. The beauty of it is you don't have to produce them yourself. You just need somewhere to put them while you distribute them. I've been accidentally been put on the Grass Carp list by the state and my phone rings off the hook.
If you could promote tilapia as a non chemical way to control FA, and would have a reliable supply to plant, that would build over time too.
Additionally, in my northern end of the state there are NO, NOTTA, NONE, ZILCH fish farms that supply fish to recreational ponds that I am aware of. We have lots of ground water, excellent clay soils for production ponds, but no one has the umf to take a chance and start one up. I'd love to do it but capital is my problem and lack of land. If I remember right you've got plenty of property to do so?
There was a time I had been happy to buy fish from suppliers, but once I was treated very poorly by the closest one in Ohio and the government slapped on interstate restrictions that's changed. I now produce my own fish and it's not rocket science. If I can do it anyone can.
