I would recommend going to the launches or slips closest to the areas you release and personally introduce yourself to the local crabbed and tell them about your program. If you have some T-Shirts give them one, if you have a cold beer offer them one, you really need them onboard for this program to flourish.

These crabbers may be running traps spread over 10+ miles; the ideal situation is they record the closest landmark, call you with info and release the crab. (GPS location is unlikely)
The rest of the possible scenarios will depend upon their willingness to participate in the program.
If you have some female colleagues I would recommend bringing them to the launches/landings when you talk to crabbers.

Your project is very interesting, and I wish you the best of luck.
