Do you know how cold your lake typically gets each winter? I ask because if it gets cold enough, the tilapia may die off each winter and thus need to be restocked each year.

Bluegill are generally considered to be the backbone of bass forage, and they won't die off. Is there a reason that you are not considering bluegill, or perhaps you already have them in ample numbers?

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."
