jig some of my favorite bait to use in such places is whats there to use small bluegill heads ( from 4" fish) are a favorite of all catfish so is using a bunch of guts on a hook. Now as for the spoonbill cats they are plankton eaters and do not bite hooks for say but i have hook them in the mouth and put them in the boat (KY lake) before and though they are very tasty fish they are one of the best rough fish to have in a lake and i would leave them alone . They eat alot of plankton and filter the water better then grass carp .
That must be a deep lake to have spoonbill catfish in it and they can get 100 pounds.
As for catching big bluegills ( 8" or bigger) try to take only the females and put the big males back in the water to protect the eggs and nest . female bluegills most allways have a yellow belly were the males are black .
Jig If you find a way to or a pattern and bait to easly catch fish out of this lake KEEP IT TO YOUR SELF and don't tell your friends or even ur mom or dad what or how .
Ok back to bait night crawlers and redworms are also my favorite but not store baught crap . Go out and dig some redworms and go night crawler hunting get on the net and learn how to make worm beds for them..
I promis you will catch bigger gills with freshly dug redwoms and more chanel catfish with fresh night crawlers then any of the crap from canada ..
One last thing jig never bring live or cut bait from another pound or lake and use it in this lake you could cause some real problems with parasite's and disease's or even worse would be to throw live bait bait from another lake or pond in the lake..
Tight lines .
