The biggest problem with obtaining a license is the inspections. To keep an illegal species, the holding facility has to be inspected prior to receiving consideration for a permit. That's a large expense without assurance of being allowed to keep the illegal species. Part of the inspection is checking to ensure that there's no chance of viable eggs reaching outside waters, including municipal water. So, strainers and UV may be required. The inspections are charged to the potential licensee. Then, part of the license agreement is to allow scheduled and impromptu inspections to check for regulation limitations adherence. These inspections are also charged to the licensee. The research license is an annual renewal with an average fee of $580/yr, plus inspection costs. And, in the end, you'll most likely be forbidden from breeding the illegal species or, must report spawnings with egg counts, hatch rates, fry losses (with proof), and may be required to tag any of the broods retained alive. You won't be allowed to sell any of the live spawn or viable eggs to recoup your expenses.
