I did a lot of bunker chunk in fishing in the fall of the early 70's. There were some important thing I learned for south shore fishing on Long that would probably apply to New Jersey beaches and the clams you use for bait. You may already know them. I still use them as guidelines when I fish bait now. Remember I only fish mostly at night. If you want to know what I learned let me know. The same guidelines should work in the daytime.
