Well I wouldn't eat one,,, its all shell ,legs and innards,, However, blackfish certainly like them.. I used to dig them up for bait when I lived in NJ.. The price is right on them, thats for sure.. In 20 minutes with a pitchfork at low time, you can get enough bait to fish all day... LOTS of fish eat them including stripers , fluke and weaks...
