As for me... I haven't figured out how to do it yet, so I sure couldn't advise others!

I do remember in the 90's, my brother-in-law taught me to catch them by dragging a flatfish in the Fall Season at 17' down. But since then... They figured me out! I guess I need to learn other techniques? Catch them? Don't catch them, It's all the same to me. I love it!
