Sk187, yes, tilapia will die and need to be restocked each spring. Stocking rate is 40# Tilapia per surface acre. or 80 pounds for your 2 acres. By dying, your other fish, turtles and terrestrial critters get fed well on the Tilapia that grew big on muck and FA that nothing else could eat

MANY pondmiesters in MI use Tilapia as a management tool for forage production, muck reduction, and FA control.

Reviews? google Blue Tilapia Toledo Blade...there are 3-4 articles on the successes.

FA is the favorite food of Tilapia...Grass Carp will not touch FA...they'll starve trying to eat it.

I don't know who in MI sells Tilapia.
