im still on the fence abou T-shad. and im down here a little south of Dallas. People lost them even a little south of my area this year. I have a 7 acre lake that im contemplating. Mostly deep water etc.
For the cost of stocking T-shad one year I can add Tilapia at 10lbs to acre for 2.5 years. Yes the shad can last much longer, yet, for one they may not take, and two we can't control the weather.
Im thinking stock Golden shiner and stock Tilapia every year and fertilize to get the most benefit from them. If i see the Golden shiner make it i may try the shad later on.
CM, in your case though atleast your pond is 2.5acres, not being a really large pond will help your wallet out a lot. If you try it and fail your not out a whole bunch of $$$.
