I'm new to the area, what type of fish are in the area and what area some baits used for fishing? what type of license is needed for fishing?

Mostly striped bass (seasonal). Some white perch, red drum, black drum, occasional bluefish. Can't go wrong with bait. Blood worms or cut bait. You'll have to get a tidal license to fish the bay and can be purchased online.

Plenty of catfish. They like bloodworms, cut bait, chicken. White perch, striped bass (protected). During the summer there are runs of norfolk spot, croakers, bluefish, drum, sea trout. You can purchase the annual Maryland state fishing license at dnr.maryland.gov

Are fish safe to eat caught from there?

That. Is not bay water. I believe it is patapsco. River
