Check with Todd Overton for stocking rates on your various ponds.
He may have sold out for this year but getting late this year anyway.
His costs are $8.00/lb
Don't know about N.E. Oklahoma but in N.E. Texas no such luck on vegetation and muck removal - FA control and forage only.
Five to ten lbs tilapia/acre stocking rate for our ponds depending upon FA problems.
Six years experience tilapia program - they are a magic bullet!
Good luck
