Don't know a lot about it, but I can tell you what the big boys down at the pool hall said...Mr. Nimrod is right on with the bait, but the bait shop at Portia did have some small carp...yes there are some monster flatheads in Lake Charles (were 2 years ago)...depth to fish depends on so many things like weather, moon, depth of prey, etc...I would start at 4 or 5 foot in the mouth of coves or at the depth and location that you caught the sunfish...use at least 50 lb test...strong hooks...not an issue when the fish is pulling the jugs, but when you grab the line and pull, a weak hook could/may straighten...break your heart...go to utube and google jug fishing...always have a sharp knife close by...may save your life...
Save the planet, it is my favorite place to fish...
