I stocked on Jan. 31 this year in a new pond approximately 1 acre when full. I based my stock rates on info I got from http://www.sdafs.org/tcafs/manuals/pond/ponds.htm
I stocked at the following rate initially. 100 catfish, 100 bass, 400 bluegill and 200 hybrid bluegill. I also put in 10 lbs of fatheads. 2 1/2 months later I added another 50 cats and 50 bass and another 5 lbs of fatheads. All were 3-4" fingerlings. I feed every day. I have caught all species already (hook with barb removed on ultralight tackle). The cats and panfish have more than doubled in size and the bass have at least doubled. All species appear to be healthy and chunky for their length. I now have cats 10" long, hybrids almost as big as my hand the all bass caught or seen are at least 8". I don't believe I have any fatheads left and know that the bluegills have spawned as I have seen fingerling size coming to sniff the food. This is what has worked for me and I believe I will be taking hybrids out this fall and some cats by next spring if the growth rate continues.
