Just wondering what other choices you could have besides warmouth or rock bass.

White Bass?

Walleye? (but maybe would not reproduce)

Gar?

Northern Pike or Pikerel?

Freshwater Drum?

Snakehead?

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."
