HI Mark,
Paddlefish are really cool. Another two species that would be fun are Burbot and Sturgeon.
I am not sure how any of these would fare in a pond, but if someone really worked it out and did it right...
Usually, an Aquaculture Facility can raise endangered species.
In Michigan, as I would guess in other states, is a permitting process and a lot of protocol to follow. The DNR's are more than happy to glean the rewards of the hard work someone else put in. They get a cut, be it information, or something to stock, not to mention the permit and license fees. Either way it is a win-win for the producer and the state.
I have seen 4" Tiger Muskie go for 50.00-75.00 each plus shipping.
That is a Niche market.
Getting into a high dollar species, one would want to be sure and secure, in a Pond environment, that it would work.
I would add more info. on how to obtain an endangered fish species (Totally Legal) in MI based on a particular exemption, then I would get Moderated, or, even worse
