This is a basic question but I am wanting to know the truth. Yesterday 9/11/15 I was out with some friends. Only 1 has ever fished before and is a "know it all" but some of what he stated was different than I remember from when I used to go out regularly (but that has been 15 years lol). We were catching many small sharks. I remember them being called sand sharks before. Can some one please inform me if that is the true name? Also is there a regulation on them? They seemed to be everywhere down off of Cape May. Some tiny about 12" others 16-18". I have heard them referred to as dogfish, sharks, sand sharks and just want to know what exactly they are and if you can keep them. My wife wants to try them, I want to try them and they seem to be very plentiful. Thank you for any help.
