Some 36,328 striped bass were caught, with 99 percent being released. Striper catches were highest between April and July, with June being the top month.
The majority of striped bass catches in the Delaware occur in the tidal portion of the river between the Commodore Perry Bridge upriver to Trenton Falls. Most of the spawning activity takes place in the tidal Delaware. There is a closed season from April 1 through May 31 to protect these fish.
The number of fish that remain in the tidal river after the season reopens is dependent on the weather. A late spring, one with high water levels and cool water temperatures, will keep fish in the river longer. Spring and early summer stripers are found in shallow water, usually from 3 to 8 feet deep. Sand and gravel flats are the preferred habitat. Numbers of younger stripers often spend the year in the river and are typically found in the free-flowing river north of Trenton Falls. These fish run in the 18- to 20-inch class.
Public boat accesses in Delaware County include Linden Avenue, Frankford, Chester and Marcus Hook. Shore-fishing opportunities are limited in this greater Philadelphia area.
