i've noticed something that i don't know if this is common or not. i have several stocked catfish ponds on my place roughly 1.5 to 2 acres they are heavy stocked and i feed them. i have a trotline ; in the pool in my back yard and this is how i take some out sometimes for a fish fry.i've noticed every time it storms i catch several fish on naked hooks. there will be no bait of any kind and no residue left . sometimes it will 2 or 3 months since the last time i baited it. i do catch more when the hooks are new; but don't know if this has anything to do with it.the fish are always hooked in the mouth. any other catmen had this to happen or can explain it?
