Marv Welcome to the Boards.
The Delaware is mostly a spring run after June 1st. The big cows spawn when the water temp hits sixty around late April. Your not supposed to target stripers during Spawning season. April 1st to May 31st . For each cow there are 5 or 6 males that follow. Some fish stay year round. Fingerlings wont migrate south with the schools until they are three years old and 18 inches. Most striped bass are caught in tidal parts of the river. The primary spawning area is the highly industrialized stretch between Wilmington De and Marcus Hook Pa. The majority of spawned adults will remain in the lower tidal portions but as the fishery has increased and the bigger guys get bigger they have been surging upriver in large schools. Stripers can be found in good numbers south of the Delaware Water Gap all the way to Trenton. There are large numbers of bass from Easton Pennsylvania on down to Trenton.
How inappropriate to call this planet Earth when it is quite clearly Ocean.
