I was just told that even if you just crab in NJ you have to sign up for the free NJ National Saltwater Angler Registry
I cryed Bull but it seams in NJ crabbing is fishing I am not sure if this is true but Since it is free I am not taking a chance Two years ago it was for people who fished for Stripers, sea bass and several others Now it looks like it is for anyone who fishes tidal waters
I also just saw it on a Bait store web site
http://tuckertonbait.com/ And since it is on the internet it must be true

Here is the web site to sign up and you must have it on your person
http://www.nj.gov/dep/saltwaterregistry/WHO NEEDS TO REGISTER?
NOTE: Anglers with a valid registration with the National Saltwater Angler Registry or have a valid license from another exempted state are required to register (for free) with the NJ Saltwater Recreational Registry Program. Registration with NJ will exempt you from having to register with the National Saltwater Angler Registry.
Individual saltwater anglers ages 16 and older MUST register if ANY of the following criteria are met:
•Recreationally fish with a hand line or rod and line, spearfish or fish by hand
•Recreationally fish in the marine and fresh tidal waters of the State of New Jersey
•Recreationally fish in marine waters outside the State of New Jersey but land the catch in New Jersey
