Efforts have been taken to reduce the pollution and increase water quality. These actions have helped the resident fish population. These include largemouth bass, smallmouth bass, sunfish, catfish, trout, chain pickerel, american eels, carp and yellow perch. Some parts of the river include striped bass, fluke, winter flounder, weakfish and bluefish. Many birds live along the length of the river. Crustaceans such as blue claw crab, fiddler crabs and green crabs are also found in the tidal sections of the river. Crayfish can be found farther upstream.
