A specialist like Cecil might be able to charge quite a bit more than $169 because of the exceptionally large fish that he raises. There are some who value quality over quantity (in time, that is) and would leap at the chance to catch a monster brook trout. These are similar situations to people who will pay thousands for a chance at a genetic freak mulie on a farm that specializes in such things. I'd talk to the largest local bank and see if they have clients that periodically come from out of town who they could "entertain" with a special fishing trip to catch a two-pound perch or a six-pound brookie. This could provide some excellent supplemental income possibilities, but only if the fish availabile are of exceptional quality.
