Deb & ML; Deb, that is a great link, and freshwater prawns are great eating and only cost 4-5 dollars per lb in groceries, headless, 25-30 count. No vein and the shells pop open when boiled for 2 or 3 minutes. Took my 86 yr old mother some for Christmas. She loves them and cant go out to eat.
ML and myself were speaking of small forage shrimp. He says that he has many if he maintains some shallow water weeds and that they just crop up just like Overton says about gambusia. Must be an Aest Texas thang.

ML, I planted rye in the basin since there is also a drougnt in SW Miss and water is very low. It will be covered with water this spring. I have never had much weed problem, but since liming, that may change, but had to. Is pondweed emergent, rooted around edges or what? I will look it up. Didnt you also say that shrimp are found in ditches in your area?
