Robert....

ML is right about overpopulation and stunting without predators. I wouldn't stock LMB unless unisex stock. Hybrid stripers would be a good choice for a predator.

So you have two choices....

1)Stock all male tilapia...we can sex them for you at additional cost for time.

2)Stock mixed sex tilapia with predator of limited reproductive potential.

To harvest your tilapia you can...
1)catch them rod/reel as described above
2)trap them
3)rig a seine trap to catch large numbers in short time. For a seine trap you'll need at a 50 ft seine left in the pond...one end on the bank and one end in the pond at an angle towards the bank where you'll be harvesting. Pond corners and coves work very well for this. Tie a rope to the end of the seine and stake it at the bank. Then just feed the tilapia for an estended period of time in this seine trap and on the day that you intend to harvest (you'll need helpers) you should feed the tilapia in the trap and then close the open end of the seine by pulling in the rope. You'll get one or two shots during the summer at a successful seine trap. If you make a mistake those tilapia will have an advantage on the next try. And FYI, they are 10 times easier to catch when water temps dip in the late fall.

Your tilapia that far south have a good chance of surviving the winter.

What else....?
