Chain pickerel are one of those funny gamefish that fall between the cracks of angling conversation. Perhaps they are slightly sexier than panfish. Perhaps they generate a baby buzz when East Coast ice fishermen are just happy something is tugging on their lines. But when that ice melts off the shallow cedar rivers and ponds in the New Jersey Pine Barrens, pickerel can save your sanity in that odd March "tweener" time when not many other fish have really woken up yet. Chasing them on the warm, marshy flats with a fly rod is a mix of bonefishing and muskie fishing on a mini scale. And to do it in the history-rich Wharton Tract, a 115,000-acre chunk of pineland in South Jersey, makes the quest that much more interesting.
