They already did, when they built the dams. The spoonbill are no different than the trout, they're raised and stocked. We've had enough experience in marketing wild animals by now that I don't know how you can get pass the history? Passenger pigeons, ducks, deer and turkey here, and the buffalo.
Human nature won't allow a person to sell the eggs from one fish, at least not until they know that one fish is documented. Value must be there or they wouldn't be farming them, and Russia wouldn't need them if they hadn't over fished their own stock. If people from CO can afford to come here and setup a buying center, take them back to CO, make caviar and then fly them to Russia, I'm thinking that a suitcase of eggs must be worth every bit of the money claimed.
