I worked on JD Murphree WMA, where TPWD's alligator program was managed, back in the 90s. From what I remember the cost per foot for a 7' to 9' gator dropped from $90-$100 / ft when the black market was really going to a range of $10-$20 / ft. The major factor was allowing licensed alligator farmers to collect eggs and start producing them legally, which killed the black market. Of course requiring CITES tags to legally sell any meat or leather went hand-in-hand with the farming program.
If the price is still what it was back in the late 90s, it would be tough making a living off alligators unless you were a farmer or one of the nuisance gator contractors in an area with a lot of human / alligator interaction.
The story of the American alligator recovery is one of the major wildlife mgmt success stories. It brought the gator back from near extinction, seriously curtailed poaching and illegal trade, and the populations rebounded in less than 30 years to the point that hunting is viable. Some folks in Florida might argue it was too successful.
If you haven't been on a gator hunt, I would encourage you to put in for the TPWD public hunts. The youth hunts are really cool because the biologists will work hard to be sure every kid gets a gator.
