The largest striper weighed in at 4.17 lbs on a state certified scale. It was a great day to get away. I live across the river from BR and would like to try it. You can catch stripers in the river right near Southern. We catch White Bass mostly.
Stripers show up from time to time but that certainly more of the exception than the rule.
White Spinner baits and Rattle traps are what we use. Are you bank fishing or from a boat. Why do you think the catfish are at that spot. The Mississippi River certainly holds numbers of Stipped Bass but the best Stripper fishing believe it or not is in the Lake underneath the Causeway Bridge. The entire length is good but the cross overs, bridges especially the two large bridges, and other assorted structural oddities always hold them.
