It would not be difficult to reduce and eliminate them from the USA waters if there was a fee paid to fishing boats if they returned them to US inspectors at the docks. Pay the fishing boats for their catch of lionfish rather than return them to the ocean. The lionfish can probably be used for fertilizer or some such thing. I am sure there are plenty of ideas for their use.

The fishermen of the USA and their families are great Americans. Very hard working. They deserve every break the Congress can afford them. Bringing in invasive species is just one way. The more invasive species populations the more competition to consumer fish harvests.
