I just put in 100 pounds of fat head minnows in my seven acre pond. Rather than having to purchase these fish once or twice a year, has anyone had success raising minnows in a large tank (300 gallons or better)? What about a small holding pond, possibly with a liner? Will they reproduce enough to give me decent numbers of fish, or would I be better off just letting them try to procreate in the pond and hopefully someday have an fairly established population. Currently I have LMB, channel cats, bluegill, crappie, and I will be adding hybrid stripers in the spring. Thanks JN
