Are you referring to 'Blowfish'? If so, GREAT EATING!!! Haven't caught any this year, however, several years ago while fishing at Cape Cod, Mass., I caught many! Don't know what happened to them, as I've already been fishing at Hyannis and haven't seen nor heard of anyone catching em (caught plenty of Seabass and Porgies with a 2 Blackfish aka Tautog). Weather has been so erratic, I decided to hit the Saltwater instead of the lake
As for Jersey... what part of Jersey? I've been to a lake called 'Farrington' (not to far off Rte 18 - East Brunswick). Nice crappie fishing there.
