Many years ago, I ran into some very ingenious youngsters floundering at night with a Coleman lantern and a short stiff cane pole with a hook, line and shrimp. They were snatching flounder off the bottom of a muddy lake in Louisiana. I asked them why they didn't just gig the flounder and they explained that the flounder would fan the bottom and muddy the water when they were gigged. But when they used their method, they could jerk them off the bottom and have them in the wash tub they had in tow, before they had a chance to muddy the area. I don't know where they learned it, but I was impressed.
The last time I checked, the leader here in Texas was 9 lbs 10 ozs. That's going to be hard to beat using dynamite!
