Winter species often most targeted in winter from land are herring, and winter flounder once they open. Now if you can get to artificially warmer water, ie. Power plant out flows, you can hook resident bass and in rare occasions blues. But for the most part if you want to fish the salt in the winter head boats for tog, winter flounder, and mackrell are about your only choices in Jersey. You could run north and hit a cod boat as well. However, once the big bass reports have subsided and they are taken over by reports of schoolies, it's pretty much over till the spring. Barring any extreme cold temps in the next couple weeks, expect to catch bass through December.
