It is almost the same situation with the Asian Carp but not as bad. They are planning to process the carp to feed the needy maybe they can do the same for the pleco. It would be a more exotic fish to eat. Maybe Andrew Zimmer from the Food Channel can promote this one.
I do believe that plecos are a staple food down where they are caught. I have seen many shows where they are right out in the food markets for sale.
Just a little boney maybe.
