Is the public allowed to fish off the park's seawall? If fishing/crabbing is allowed, are there places where is is prohibited? Someone already asked, but I didn't see an answer.

Yes wall on Mathis Plaza & food Truck

Yes fishing is allowed off the wall side where "Mathis plaza" is - adjacent to huddy park near the hot dog trucks Lots of people there daily

I am not really sure. Most places along the river, they require a license. Call the police department and ask.

Yes
