Ok I have a 4 acre pond in my back yard. The left 1/3 of it is 2 feet deep, the middle third doesnt get any deeper than 8 - 10 feet which which sloaps to that depth pretty quickly from both sides and then the right 1/3 is about 15 - 20 feet and is deep frm end to end to form kind of an under water T shape. I am in ga so the water get lots of rain, has an under water spring and is pretty warm to the touch. I have caught lots of nice bream, in the spring quite a few bass about a pound or less, and also during the spring I slew a gross of crappie which are spawning in the pond. Last year I caught off of different baits 3 12 - 15lbs channel cats my brother in law caught a pan sized channel and my nephew caught what looked like a 1lbs flathead. But I am not certain had underbite and was tan. This year I have caught squat for cats and I CPR them all. What do you think the deal is and what can I do to change this. I see lots of minnows, tadpoles, frogs. For these fish to eat so why is the cat population so crapy?
