MC,

Dont know the answer to your questions.

I would suspect he is smoking them, cant see where he could get enough to actually make any money selling them.

Id suspect he would only get 2 or 3 a day up there if the net was set all the time, more with high water maybe.

the net we found was a 25 foot or so mono gill net with 4 inch mesh or so, dont know about the one he had this time.
