(I'll let ewest comment on the stocking #'s since it's a southern pond.)

Ewest, on the question I had about stocking my pond. It was measured by the county its more than half an acre like .65. I have structure made of pallets shaped into triangles (3) and (1) made like a box with a Christmas tree in it. I have (3) 6" pvc pipe trees. Can you create to much cover for a pond my size? All in all I have 7 structures located throughout the pond.
