We live on an approx, 7-8 acre shallow lake. in NE PA Deepest water is about 5ft. Most of it is about 2-3ft. This lake is 85% covered in Lilly pads in the summer and stringy green algae.

We know there are Blue gills, and cat fish in it. It also has lots and lots of turtles. Painted and snapping.

We would love to add some Tilapia to help eat some of this crap in this lake. But I understand for a lake this size it would take lots and lots.

We would like to experiment with this though and want to know if we should get some larger like 3-4in ones or 100 fingerlings? I'm Assuming some larger ones as they should breed more quickly and not as likely become food for the other fish.
