I got one for thought. A friend helps around my house and her husband goes fishing for crabs! He makes a tube out of PVC pipe, swivel as in fishing at the top, cap at each end then drills 1/4 inch holes in it. (lots of them) Then small eyes are attached to anchor plastic line hanging all around with hooks on the end.

So puts clams in them and with a beach rod throws it out as far as he can get it in the surf. After some time reels it in and the crabs trying to get to the clam bait are are tangled in the tube lines and get reeled in.

I have a picture if anyone doubts it but d--- I didnt know about this!!!
