N.TX.Half Acre, in general, many of us feel the recommended per acre number of grass carp is too high (even though I can't recall the specific number).
Having said that, I would not put more than 1-2 grass carp per acre in any of the ponds. Maybe 3/acre if you've got a real bad vegetation problem, and in that pond, maybe it'd take 2-3 years to come under control.
