We'll have to wait and see if they add the crabbing section to the site
As far as crab baitss goes. You can use just about anything.
I've used the below baits and have great results.....
Chicken necks and backs
Turkey necks
Bull lips
Bunker
Any fish
You want a tough bait that will last long and not break down/ fall apart fast.
I use drop lines & dip nets as well as a crab trap.
Let me know what area you are from and if I know of any areas, I let you know.
Good Luck!
