Just curious....are you doing any feeding?

Regarding those who pay to come fish, is it you who gives them an 'orientation' before they fish? I'm asking about how viable it is to harness their activities towards your goals in the most effective way.

Also, what do you feel the role of the tilapia is in this pond?

Excerpt from Robert Crais' "The Monkey's Raincoat:"
"She took another microscopic bite of her sandwich, then pushed it away. Maybe she absorbed nutrients from her surroundings."
