My limited experience with WE in my pond has not yielded good growth results.

I have tremendous amounts of forage fish, yet the WE have not grown very well. They were stocked at around 14" if I recall correctly, about 2 years ago. They are now maybe 16" tops.

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."
